Does it work with my system?

Select your car

Find what fits your car

You can take it with you. Just because you've got a factory radio in your General Motors car, doesn't mean you have to leave your iPod (and the hours and hours of music it contains) at home. Just install USA SPEC's iPod interface — it not only allows you to listen to all your favorite tunes through your car's speakers, it even lets you control song and playlist selections right from your radio. And with your iPhone® connected, you can even stream music from popular Internet services like PANDORA®, Livio Radio, iHeartRadio, and more.

Just mount the compact interface box in a hidden location in your vehicle, and connect the adapter cable to the CD changer input on your compatible GM factory radio. Plug your iPod into the interface — you can control volume, source, song selection, and up to five different play lists right from the radio. Or switch to "Direct Mode" and use your iPod to access all your songlists. And the interface charges your iPod while it's connected.

Please enter your vehicle information or call an Advisor at 1-888-955-6000 to find out if this adapter is compatible with your vehicle. As the iPod interface uses the CD changer port, any existing changer that you have must be disconnected.

Compatibility Note: Be sure to check "Details" for specific iPod model compatibility with this iPod adapter.

Product Highlights:

  • iPod connection adapter for select GM factory stereos
  • manage the iPod via your radio's CD changer controls
  • adjust volume, track up/down, fast forward/rewind
  • use up to five playlists (select five favorites, or Auto Playlist will let you choose from the first five on your iPod)
  • when iPhone is connected, you can stream tunes from popular Internet services like PANDORA®, Livo Radio, and iHeartRadio
  • Dual Mode allows you to control everything via the iPod itself, giving you access to all playlists
  • compatible with all iPod and iPod mini models equipped with a dock connector and iPod software update 2004-04-28, or higher
  • warranty: 1 year
  • Our 60-day money-back guarantee

Why would I need an iPod® adapter?

An iPod adapter allows you to connect your iPod to your car stereo, then access your playlists with your stereo's controls - a great idea for several reasons. One, you can scroll through your song titles on your stereo's larger display, instead of squinting down at your iPod. Two, you can route the adapter cable to your glove compartment or center console, so your iPod stays safely out of sight. Three, the iPod adapter keeps your iPod fully charged, so it's ready to rock when you leave your car. And last of all, some adapters bypass your iPod's internal digital-to-analog converter, using your stereo's superior DAC to turn your files back into music.

Extremely dissatisfied with this product

Written By JoeB, Albuquerque, NM on Sunday, December 11, 2011

Crutchfield Customer Review (What's this?)

Conceptually a great idea however in function it lacks reliability. When it does work the sound is acceptable and functions according to the user manual. Looking for a replacement for my wifes 2003 Tahoe.

Cons: The unit requires constant resetting to enable functionality, quite annoying! I wave went through two units both have similar issues.

2005 Yukon Bose

Written By Mark, Atlanta, GA on Sunday, March 21, 2010

Crutchfield Customer Review (What's this?)

Great product. GM has a history of leaving plenty of room to work around when installing extras. I mounted the unit underneath the cup holds, drilled a small hole in the base of the center console and ran the cable tat connects to the iPhone in there. What is nice is the lid to the center console does not seal completely on this model vehicle so I can have the cable out just enough to stay neat while leaving the iPhone in the cup holder or storage bins for easy access. It allows for use under cd changer or xm radio options.

The only problem is this unit will not charge an iPhone.

2006 Hummer H3

Written By John, Utah on Thursday, January 21, 2010

Crutchfield Customer Review (What's this?)

Returned first unit. It kept showing XM error and dropping offline. Both units would sound like a record skipping when switching bands. If you have to replace the box. The bliue XM wire can be difficult to disconnect. Large wire going to radio vibrated out several times until I rerouted the wire in a bog loop around the adapter.

Second unit started putting out poor quality sound from ipod after being installed just over 1 month and scratch noise when switching bands started to get worse. Got fed up and removed it.

Unit was installed on top of radio with heavy duty velcro so it did not move or vibrate. I would not recomend this adapter.

2005 Escalade

Written By Anonymous, Newberg, OR on Saturday, December 26, 2009

Crutchfield Customer Review (What's this?)

Information provided by Crutchfield for removing trim panel was spot on. As long as you get an edge started (by headlight knob) it is pretty easy to just pry it off by hand. I would suggest after removing the stereo to also remove the A/C controls (only 2 more screws) to access the rear of the radio even better.

I ended up locating the main unit under the dash near the gas pedal so I would have easy access to it in the future if needed, the cables were plenty long enough for it. The only trick was trying to get the connector for the XM radio to come off (still couldn't get it off, but was able to find the 'Data' wire and splice into it.

I was being extra careful during the installation, and it took me about 2-1/2 hours, that included testing it before I did the final assembly. Enjoy!

Simple, Effective Solution

Written By Anonymous, New Orleans on Wednesday, December 23, 2009

Crutchfield Customer Review (What's this?)

This product was easy to install and works as promised in my '06 Suburban with factory Nav and XM. I spliced the (tiny) XM output wire and mounted the unit behind the glove box. You'll need your own splicing stuff (butt splice, wire nut, or whatever) since it's not included in the package. I decided to run the iPod connector wire into the glove box, using the small left-hand section of the divided box. This required drilling one hole in the base of that compartment of the glove box, but the end result was an entirely clean, out-of-sight solution. The interface is a little quirky, but it's a great solution for a retro-fit. I made five new playlists in iTunes and titled them "a", "aa", etc., so that the unit would read them first and we can toggle through them with the steering wheel controls. It also lists the artist and song name on the screen. I removed the AC/heater control module when installing to give me easy access to the back of the radio when reinstalling head unit. This made the often-mentioned problems with getting the factory unit back in the dash a non-issue. I have zero experience installing car stereos, but am fairly handy -- this was easy. Removing the instrument panel cover in a Suburban is a breeze if you just take it slow. Sound is great. Excellent product, highly recommended.

2003 GMC Yukon Denali

Written By friedscorpion, Little Rock, AR on Thursday, November 19, 2009

Crutchfield Customer Review (What's this?)

You HAVE to follow directions EXACTLY. No shortcuts. My Yukon has AM/FM/XM/single CD/6 CD changer and I wanted to hook up my iPod and/or iphone 3G s. The "XM1" becomes the ipod/iphone; The "XM2" becomes your normal XM signal. The steering wheel controls volume up/down/next song. It re-charges perfect. My only complaint is that you HAVE to cut the "data" wire (LIME GREEN) in the no.7 position from the XM receiver which is located behind the glove compartment. Once the wire is cut, you have to tap-into this lime green wire with the provided blue XM wire. It's not a big deal, just a step I didn't anticipate. I mounted the interface behind the glove compartment and ran the wire to my ipod/iphone around the edge of the console so that it's lying next to my cigarette lighter for easy access. I recommend it.

Crutchfield Customer Review (What's this?)

I just installed this product this morning. so far it works great. i have it
going through the xm radio since and it works great. i have it in direct mode
mainly because i don't care if i can read the info on the radio screen and it
seems like it has the least problems from past reviews. first off read old
reviews they are very helpful, couldn't have done it without them. i found it
very helpful to use a coat hanger to run the wires. I'd run a coat hanger then
tape the wire and pull it through. as stated previously the hardest part really
is putting the radio head unit back into the slot. i put a coat hanger through
the gauge area to pull the wires to the back left as i slid the receiver back
in. also as stated before the xm receiver is behind the glove box which is
easily reached if you adjust the glove box stop latch and pull the glove box all
the way down. the xm wire you are looking for is green. all together took
about an hour. pretty easy and no problems so far.

Nearly Perfect

Written By ecrist, Minneapolis, MN on Wednesday, June 17, 2009

My wife purchased this for me for Father's Day 2009. I did quite a bit of research on this and the other (Peripheral) unit, and people seemed most happy with this one. I love this unit. It took me, for start to finish, less than 15 minutes to install. I installed this unit in my 2004 Chevrolet Silverado, and put the device in my glove box. On my model-year truck, the glove box is split into three sections, on the left is a narrow 'cubby' which is where I put this unit, with the iPod/AUX ports facing out. Looping the radio cabling over the back edge, it routed easily to the back of my factory stereo.

The reason for four stars versus five is that, in Hybrid mode, at least with my iPod Photo, it never leaves the 'GM - OK to disconnect' screen. My wife's iPod Nano leaves the screen, but after nearly 5 minutes. Direct mode is a great, and still allows me to use my steering wheel controls! Pause/Play on mode change and 1 hour of charging make this thing feature-complete.

'05 Colorado: Burned thru 2 of them

Written By Emily, Pittsburgh, PA on Sunday, May 17, 2009

Crutchfield Customer Review (What's this?)

Got a 2005 Chevy Colorado Crew Cab, factory installed radio with no USB port, iPod connections, or XM radio. I have a 5th gen 60BG iPod. I used to have an adapter that I had professionally installed which lasted for a year before it died. Bought this one in Jan'09 from everyone's recommendations here. I installed it myself (the instructions supplied were ok, included instructions to replace the door speakers which I didn't need & the manufacturer's choppy English instructions on connecting it to the radio). However the instructions to operate the iPod thru the radio or by the iPod didn't match what was happening - with the previous one I just hit CD/AUX to use it via iPod (it plugged into the headphone jack not the charge port.) This product I had to hit the BAND button to get to the iPod but my radio's readout said "XM 1". It worked for 3 months then the readout said "XM ERR" and stopped working. Installed the replacement Apr'09 and I'm getting the same error/dead adapter 5 weeks later. The 2nd one first worked via CD/AUX first time, then would only work via BAND. All white switches were ON, tried 1&2 ON, 3&4 OFF. Still isn't working. Very annoyed & I'm returning it too. The dashboard is almost broke from removing it so many times & the buttons for the A/C & circulating air are damaged from the radio. Now I'm going to have to pay more for a brand new radio just to play my iPod in my truck. My truck is driven on city/highway roads only.

05 Sierra - Factory XM not being used

Written By Billy, Grand Forks, ND on Friday, May 08, 2009

Crutchfield Customer Review (What's this?)

WOW - great product - excellent sound - couple of difficulties to share though.

1. - I used XM integration (instead of CD Changer) so I could get title/artist info on the display. - I have factory XM, but not activated (Too much $, not worth it). SO I disconnected the XM and only installed this device. - Radio had a hard time detecting the change - it kept wanting to connect to XM receiver. Wound up dropping the glovebox, disconnecting connector at XM receiver, then it seemed to lose the XM options - re-plugged in this kit and things started working as they should.

2. - XM Error would come up occasionally (2-3x so far) - I'm thinking it was due to static/something relating to hooking up the aux. jack. - Problem hasn't occurred since stopping using the jack. - I think things would show back up with a restart of the vehicle, but that's a pain.

3. - Title/Artist only show the first 5-10 characters - no big deal here.

4. - Playlist functionality, etc is excellent! - Steering wheel controls work as they should - only tip - move slowly when changing "Disks" - it must do some macros on the ipod and it can get confused if you jump too fast from "disk to disk", however you can seek up and down as fast as you like.

5. - Start/Stop, pause, etc. - AWESOME - super fast - shut off the radio - pauses your song - turn on the radio, it picks up where it left off faster than a CD would. - GREAT!

6. - Audio quality is perfect - did I say that before? - WOW

This is great, I had some questions about the install and the tech staff at Cruchfield were great. You dont need to cut the wires that the instructions indicate if you dont have XM in your vehicle. It is nice to have both my Ipod and an AUX hookup in my car now that is in the factory nice.

This is perfect

Crutchfield Customer Review (What's this?)

This was soo easy to install it's not funny (nothing compared to my other car's stuff). I think there were only 2-4 screws involved. Tip - move shifter around if automatic to get clearance when removing dash facing (for chevy and gmc applications). I set it to 2 off, 2 on (in that order) and Ipod / IPOHNE (they both work) shows as disc 5, I added an aux input which is now disc 6 (this unit shows up as an imaginary CD changer). Sound is perfect. Works exactly as it should and retained my rear DVD function :-) Very pleased with the product.

2004 GMC Yukon Denali (Bose, XM, CD Changer)

Written By Anonymous, Forest Lake, MN on Sunday, February 15, 2009

Crutchfield Customer Review (What's this?)

I only give this product 2 stars because I had so much trouble with getting it to work. Installing (removing dash trim, removing radio, hooking up wire harness, routing cable, reinstalling radio and trim) only took me about 1 1/2 hours. The problem was getting it to work. The din settings were a little confusing but my biggest problem was that every time I shut my car off and restarted it the USA SPEC wouldn't be recognized. I kept getting the message "NO CDX magazine" "no music disc." I would have to unplug and replug the USA SPEC in to get it to work. Big hassel since I mounted it behind my glove box.
I called Crutchfield and got a replacement sent to me no problem. The service at Crutchfield and product support was A+.
I then completely re-wired and reinstalled the new USA SPEC. SAME PROBLEM!!
Finally after hours of trouble shooting and research I read an earlier review in which the person had the same problem. Sure enough their solution worked. Now whenever I restart my car I have to unplug my Ipod (once, twice, maybe three times) to get my radio to recognize the USA SPEC. Not a big hassel but definately not the convenience or the performance I had hoped for.
GOOD LUCK if you own a 2004 GMC Yukon. I sure hope you have better luck than I did.

It works, But....

Crutchfield Customer Review (What's this?)

First I will say Crutchfield has come through with great customer service.

I recieved my first unit very fast, and when I tried to install had many problems. First the cable for the ipod would not even connect to the PA11 because it had the wrong connector. So right away I called crutchfield and after about 5 mins on the phone a new one was on the way. Shipped that day.

Tried using AUX settings until new one arrived, and it worked for all of about half a day. Then quit, not sure why. So just waited and installed new. Works great so far. Only problem we are having now is some where in the process we lost the CD player all together. There are 6 disks in it, and the radio says no disk. Oh well I guess. Something to figure out later. Still hoping this thing works for more than a day.

Only lasted 16 months

Written By greg, Pawleys Island,SC on Tuesday, December 16, 2008

Crutchfield Customer Review (What's this?)

I really enjoyed the unit while it was working, but it only lasted 16 months.
That's approximately $10.00 a month. You would expect a quality
electronic devise to last for years and years, like a car radio.

I'm looking for something else to try now!

Installation gliches

Written By Lawrence, New York on Saturday, November 08, 2008

It is not as hard as it might seem to install. One thing is make sure you put the shifter in neutral or lower on the console before disconnecting the battery since you won't be able to remove the panel on the console. The product is not as versatile as I had hoped as far as choosing what you want to listen to on your ipod. You need to select many things on the ipod itself before just using the cd controls. If you make playlists then it would be easier for choosing but you have to do everything in a linear way i.e. you can't just go to the bottom of your list, you have to go one at a time to get there.

Didn't work for me

Written By Keith, Maryland on Tuesday, October 21, 2008

Crutchfield Customer Review (What's this?)

The rating is not a reflection on Crutchfield. They weren't aware of the problems with the product, and have been very helpful. I intend to buy a replacement solution from them this week.

Purchased this device for a 04 Chevy Silverado w/factory Bose. I opened the box to find 3 supplemental notes notices inside. One warned me Hybrid Mode doesn't work with some iPhone/iPod Touch devices, a 2nd warned me the product will not charge some iPhone/iTouch models, and a 3rd warned me about the availability of an extension cable.

Basically only one of the major features works. In the end, I couldn't justify paying this much for a simple direct connect (auxillary input connector) when I can get one for less. Very disappointing. There are no USA Spec managers or execs in the US to speak with, so there was no way to escalate my concerns. I was simply told the company was in process of designing a replacement cable that would allow the unit to charge my device, and that it would cost another $20. The new cable still wouldn't enable the Hybrid Mode or the other missing features.

Won't charge my iPod
Doesn't work in Hybrid Mode
Can't manage the device from radio or use steering wheel controls
Works only in Direct Mode

The Crutchfield Support people in Virginia were terrific, and understood the situation. They issued a return ticket within minutes of my decision to send it back.

Doesn't work with iPhone

Great product - easy install

Written By Robert, Seacoast, NH on Tuesday, August 05, 2008

Crutchfield Customer Review (What's this?)

I ordered this IPOD adapter for my 2004 GMC Yukon XL. I had previously been using an FM transmiter type adapter which always had static and had sounded lousy. The product showed up quickly.

I do consider myself at least at the moderate skill level when it comes to installing things like this. I find the install manual adequate at best, some of the directions were vague and it could use a re-write and better graphics. The actual install took about 2 hours, and I wasn't rushing and being very meticulas. The onyl minor hitch was splicing into my XM receiver box which is located behind the glove box. The wire that comes with the kit is around 12-14" long and the length you actually need is about 36". No problem, just splice in a longer cable. But given the price of 20g wire, come one folks and just give us a longer wire.

I only hesitate to give 5 stars because of the manual and wire issues. My Ipod never sounded so good and I control it from the factory controls on my stearing wheel.


As advertised!

Written By Michael, Baltimore, Md on Friday, July 25, 2008

Crutchfield Customer Review (What's this?)

My order arrived yesterday afternoon, only 36 hours after it was placed.

Almost immediately I read through the installation manual and then started the install on my 2006 Yukon XL. In under an hour, I had the install completed and the vehicle dash completely reassembled. The instructions were right on.

The product works exactly as advertised. In short, it works great! No more crummy FM transmitters, I am very pleased!

The only caution I would add is that, contrary to what would seem typical, the DIP switch positions are reversed, that is, down is ON, and up is OFF. I almost set them incorrectly because of this. However, closer attention to detail on my part would have prevented this near mistake.

Great product for someone with an older vehicle that wants to retain the factory radio.

USA Spec GM / IPOD interface

Crutchfield Customer Review (What's this?)

I installed this in my 05 GMC Sierra 2500HD with factory 6 CD head unit with Bose. I also have Onstar and XM. I wouldn't consider myself a mechanic or anything, but the install was essentially plug and play with the exception of finding and splicing one wire on the XM receiver. A little clearer instructions on finding and identifying the XM box would have been helpful. On my truck, I needed to cut and splice the green wire. Operationally, the unit works great on XM 1 band. (You'll lose half of your pre sets on XM but a small price to pay). As others have said, it sounds awesome, just like you'd expect coming from your IPOD, although it won't display song or artist info. Also as usual, Crutchfield steered me right on this purchase. I'm sorry I waited so long to get this. A must have if you have a GM radio and an IPOD.

Crutchfield Customer Review (What's this?)

Let me start off by saying the sound from this is AWESOME!! I had been
using a Belkin FM Transmitter, but it always had a lot of static. This unit
provides crystal clear CD quality sound.

I installed this in a 2003 Impala and getting the dash off and the radio out
were a breeze with the instructions provided. Getting the wires all tucked
back in was another story. It took me over an hour and all kinds of
manipulation to get the unit back in properly. There is just not enough
room in there for the extra wires. Total install time was about three hours.

My only disappointment is that it doesn't display the title on my radio
display, but the sound is great and that makes up for it.

I would definitely recommend this unit to anyone looking to enjoy their iPod
in their vehicle.

Another nice plus is that it has an extra input for connecting another device
via two RCA style plugs. I have an external (Delphi) XM radio that has a
built in FM transmitter that was better than the Belkin, but still would have
static and was a pain as I travel quite a bit and would have to always
change the station. I can now plug that into the extra input and play it
directly to the radio.

I have a 2005 GMC Envoy SLT w/ BOSE & XM, and I tried the "OTHER" only Ipod interface our there for GM's. Don't even bother with that other one. It was nothing but Data Noise, and I could not get the volume up enough to really sound good.

The USA-SPEC is the best out there. Like other reviews state, it sounds awesome. Like the inside your car was the inside of your head with ear buds on. It's that good.

Read the all the other GM reviews and the install is just like they say. Not hard at all. Be sure to drop the panel down & remove the XM unit for the harness mod. Trust Me you'll be happy with this interface. IT ROCKS!

USA Spec iPod® Interface

Written By Mark, Chicago, IL. on Monday, April 28, 2008

I installed it in my 05 GMC Canyon, factory radio with CD, XM ready but no XM receiver (so I didn't need to do any splicing), no CD changer.
Installation was easy about 1 hr, removing the dash trim plate & radio was easy with Crutchfields instructions. Harness worked great, just plugs right in, only needed to attached 3 of the 5 harness ends. Using it as XM in playlist mode (locks out ipod) hybrid mode does not work with my 3rd generation Nano.
Sound is awesome, works great. I've had it for over a month now with no problems. I would recommed this product for it's great sound.
The seek, scan, fast fwd, rev, #6 random, #5 playlist, buttons control the ipod.
The only flaws (for me), it does not display the artist and song constantly on the radio, you have to press the DISPLAY button (INFO button does nothing) to see what's playing, and
there is no way to speed through the playlists (1000 songs) in playlist mode, to get to the song or artist you want. (You can in the direct mode via the ipod).
Those are only it's MINOR flaws, otherwise it's a great product, you won't be disappointed.

Works great but beware of things they dont tell you.

............................Things They Dont tell you about this unit............................
if you i-pod is firmware version 1.2.3 or version 1.1, you will not be able to
control your ipod via radio controls(hybrid Mode) new ipods are now at firmware 1.3 For new ipod owners,buy at your own risk.
I could not get the unit to display song names or artist even though I hooked it up via XM installation proceedure and had dip switches correct.
Beware: the harness they give you has two matching black connectors to
plug you module into, the module will plug into both of them but they are
wired differently and the instructions say nothing about this. Plugging into one made my radio display my i-pod as a CD showing disc,track and elap time. the other connector made it display I-Pod,artist and song so test it first before you put it together.
The good news,once I got around the above issues,I have been very pleased with this system, perfect signal quality,control of my I-pod and
can read my songs via radio display. I hide the I-pod and none of the car thiefs can tell I have anything in my car while I am sporting over 3000 songs
onboard at my fingertips..... Good bye CD's,XM,Radio,poor signals,static and
comercials(unless I want to hear them).
Overall a Great unit,very pleased with it and would recomend it.

2005 GMC Yukon XL Denali, Nav, CD and XM

Written By Goran, Richmond, VA on Thursday, March 13, 2008

Crutchfield Customer Review (What's this?)

Installed into my 2005 GMC Yukon XL Denali with Navigation System, 6-disc CD-Changer, and XM. The previous reviews are absolutely correct. If you follow the excellent installation procedures for your particular car provided by Crutchfield, it will be installed correctly.

First step was to remove the front panel of the dashboard. This is simply snapped on, and you can remove it by pulling it towards you, gripping firmly from one end of the panel to the other. Make sure your steering wheel is in the lowest position, and your gear shift is in the lowest ("1") position.

Second step was to remove the navigation system (radio). Three screws holds it in. After removing all three screws, carefully pull the unit out. Mine felt like it was in there pretty snug, and I was very careful to slowly pull it out, trying to feel for any "snags". I was able to pull it out just enough to get my hands in behind it to disconnect the four connectors into the unit. One connector is the antenna that you can pull straight out (located on the very right, looking from above), one connector is a single green wire that you need to push a release button to disconnect (I assume this is the ground, which is located second from the right), the two connectors on the left are what I assume connects your CD changer and XM receiver. These two connectors are snapped in, and you need to pinch these to unlatch them from the navigation unit.

Third step is to figure out where you want to put the iPod interface unit. In this particular car, there is a convenient place for it in the glove box. To the very left in the glove box, there is a seperate compartment that does a pretty good job holding the interface unit. From this location you need to feed the cable that goes from the interface to the Nav Unit and the blue wire from the interface to the XM receiver. The XM receiver is located behind the glove box to the right. With some fine motor skills, you can feed the cable from the interface box to the Nav Unit behind the dash board. The wire to the XM box can be taped to the wall behind the glove box. On the XM box, on my car, I found that the data wire for XM1 was the "GREEN" wire. I cut it, and connected it with the blue XM data wire from the ipod interface.

Fourth step is to connect the iPod to the interface. Use the supplied cables, and it will work like a breeze. The switches on my unit are set to 1-On, 2-On, 3-Off, 4-Off. This is "Hybrid" mode, using XM1 to access the iPod. I can see the text of the artist and song on the nav unit, and use the steering wheel controls to forward/reverse, etc.

Oh, and when pushing your Nav unit back in, be careful of all the cable harnesses in the back. There's some room to the left where you can kind of guide all the cables towards as you push the unit back in.

The dashboard panel snaps in as easily as you took it off.

I have superb sound quality using this interface!!! It's really cool!

Hope this helps!

Crutchfield Customer Review (What's this?)

I researched for approx. 3 months before buying this product and have no regrets. It did not work after install...and I called the tech support whom helped me diagnose that I locked up the factory stereo by changing dip switches with the power still on. Tech support showed me how to reset the factory stereo and It works great.


Written By James, Oklahoma on Thursday, February 21, 2008

This is a great unit. I looked around for about 4 weeks before buying this. I have a 2003 GMC..... factory radio CD6-with out XM.
The install was very easy. connections easy as well. come with all the wire harness needed. I mounted the unit under the cup holder in the front console.I ran the Ipod cable thru a hole I drilled at the top of the lowere cubby hole . When Im not using the IPOD I just roll the wire up and leave it in the cubby. I set the switches to work with xm, which I didnt know I had..and set the aux switch to on. I mounted a 3.5 plug to the dash and connected the rca 's to the unit's aux. now I can connect my GPS unit to the trucks radio as well as the IPOD. Works with the sterring wheel controls and direct from the IPOD. It displays the song title and name of song on the factory radio... Great deal and grreat price

2005 Yukon XM, 6 disc,Bose

Crutchfield Customer Review (What's this?)

This product is perfect for what I was looking for. Please read the other reviews prior to installing this device. I found everything very easy once I read the instructions. Total install took about 2 hrs. I had one problem after I installed it. I had no right side speakers. I called Crutchfield and they suggested that they send me a new unit. I just got the new one installed and everything works great. I am even able to use the cd player. Buy this unit and you will not be disappointed. I was a little nervous about hooking up the blue wire to the XM box. I used a butt splice for the connection. It was very easy. If you are at all mechanically inclined this will be simple. The only reason I gave it a 4 was that I had to wait a week for the new one to come. Crutchfield was excellent all the way through. I will buy from them again and again.


2003 GMC Yukon Denali install

Written By Ed, Cupertino, CA on Tuesday, February 05, 2008

Crutchfield Customer Review (What's this?)

I purchased the USA Spec Ipod interface for my 2003 GMC Yukon Denali. Installation was very easy and was a plug and play installation with only XM data wire needing to be spliced. Everything was easy to get to and the unit tucked in nicely behind my glove box. I had been using the Monster FM transmitter to play Ipod in the vehicle but results were unsatisfatory. The USA Spec unit allows a direct connection and the sound is terrific. The bonus of having another audio input is a plus for future expansion. I was especially pleased that I did not lose the functions of my factory installed XM, Navigation, On Star, or CD changer.

USA Spec iPod® Interface

Written By lw85215, Phoenix, AZ on Monday, January 28, 2008

I installed the interface in a 2007 2500hd chevy silverado. The installation instructions from usa-spec were very detailed and helpful. My interface resides on the xm1 band since I have xm and onstar in the truck. I only had one glitch with the unit. It gets a secondary power from the radio on a yellow wire that chevy calls "retained accesory power", if you turn the key off for the vehicle and turn off the radio and then turn the radio back on sometimes you get a "xm error" on the display of the radio, and your xm bands are gone. The problem is still hit or miss though, it doesn't do it everytime. You can fix this by pulling the fuse to the radio which resets the radio and the usa-spec box and everything works fine again. I found that if I just leave the radio on and never mess with the power button and let the radio turn off when the doors open everything works fine all the time. I also run my overhead dvd audio into the aux audio jacks on this box and it sounds great. I am very pleased with this interface and would recommend it to anyone. Hope the review helps some of the chevy folks out there.

Good Product

Crutchfield Customer Review (What's this?)

Bought it about a month ago and installed it. The hardest part for me was getting the connections off of the radio, once I got them off about 40min. later I installed the adapter and stuck everything back into place, believe it or not I didn't have any trouble getting it back in. Since I couldn't find the XM receiver even though I know it's behind the glove box ( there are like two different "receiver" looking things back there that I don't know which one is which) Anyways I connected my iPod and I switched it to XM1 and it started playing. So I didn't even have to splice into the XM receiver and I can still use my 6 disc CD player. Only bad thing about this and the sole reason I gave it a 4 star rating is for the simple fact that the name of the songs don't show on the radio. Even switching it to playlist mode. But other then that this is an awesome accessory for any iPod owner.

Chevy Colorado w/XM

Written By Frank, Houston, TX on Wednesday, December 26, 2007

Crutchfield Customer Review (What's this?)

I am a big fan of these devices. This is my 2nd one. Nothing beats the sound quality. I had tried FM transmitters and they were horrible. My first USA Spec IPOD Adapter went in my '01 Suburban (single cd, OnStar, no XM). I simply used the CD changer port on my head unit. The install sheets from Crutchfield made it easy. The 2nd USA Spec IPOD Adapter went in my '06 Colorado (6 disc changer, OnStar, FM). The hardest part on the Colorado install was finding the XM receiver. In the Colorado it is located above the roof of the glove box. Take the glove box out and then pull the roof down and towards the front seat. Its plastic, made to bend and is held in place with two clips. If you don't have an XM subscription you don't have to splice anything - simply disconnect the antenna lead and you're all set. In both vehicles I put the adapter under the consoles. In the Suburban the cup holder easily pulls out and in the Colorado the tray easily pulls out of the console.

Crutchfield Customer Review (What's this?)

This product works great. I have a 2006 GMC Envoy with the base factory stereo (No XM, No Bose, No Nav, and No CD Changer). I first took my car to have the peripheral electronics model ipod adapter "professionally" installed - What a joke!!! The guy installed in completely and then told me that it wasn't compatible because i don't have the CD changer and he couldn't get it to work. They took it all back apart and told me i was out of luck. I had my doubts that it was the end of the line and found this great product on Crutchfield. I installed this myself in an hour and 15 minutes and had no problems. Followed Crutchfield's great install instructions just popped it in, turned it on and worked the first time, no problem at all. Thanks to Crutchfield and USA Spec i'm loving my new ipod hook up!!!! Great product, great service, great instructions - i couldn't be happier!!!

Things to know for Impala Owners

Written By Tony, Palmyra, PA on Monday, December 10, 2007

Let my start off by saying I couldn't be happier with this product!!! For Impala (00-05) owners with XM, the XM receiver is located in the trunk on the passenger's side. The head unit is quite a pain to re-install because of the limited space for the new wire harness. I managed to move the smaller connectors of the harness over to the right (with the unit itself) behind the air duct. I then used a ruler to hold the bigger connector to the left side while pushing on the head unit. That part probably took longer than actually connecting the iPod interface. You'll also have to splice the XM data wire in the trunk and run a wire up to the iPod interface, which isn't as hard as it seems. Thankfully Crutchfield sent instructions to take out the back seat. Overall, is wasn't that hard of an install, and it was VERY well worth it!

Works well with flaws

Written By Sarah, Denton, TX on Saturday, December 01, 2007

2005 Yukon Denali with Bose and XM.

This unit works mostly as described except for a few flaws that other reviews have already pointed out.
+ Great sound quality (after playing with the stereo and iPod eq's)
+ Retains steering wheel and factory head unit controls
+ Playlist and direct mode
+ Random in direct mode works well.

- Random in playlist mode must be used with the ipod controls, the factory stereo controls usually pick the first song in the list.
- I wasn't aware that I would lose the use of my CD changer
- Everytime I turn the car off and on I have to disconnect and reconnect the iPod, this is annoying for quick stops like gas.
- Currently the unit is interfering with XM even though I have it set up for CD changer. (playing songs and XM channels at the same time) I think Crutchfield will help resolve this.
- Slight feedback whine, usually covered up by music.

The unit is certainly not perfect, but I think it is as good as you can find right now. Being able to use my iPod all the time with quality sound makes up for the flaws.

Works in SSRs with factory Bose/6 CD system

Written By William, D/FW, Texas on Tuesday, September 25, 2007

I have 2 Chevrolet SSRs: an '05 and an '06, both with in-dash 6 CD changer and Bose system. I bought one last week and installed it today, and it works great. The reported inability to advance to the next track using head unit or steering wheel controls, without taking the iPod out of shuffle mode, is the only drawback I've heard of so far (haven't confirmed it firsthand yet).

I'm going to buy another one today for the other SSR. It's a pain to install, but that's Chevy's fault, not the manufacturer of this device.

If you have an SSR and a dockable iPod, I highly recommend this upgrade. I placed the unit in the glovebox (secured by velcro), and that's where I store the iPod as well.

2005 Silverado with Bose and XM

Written By Steven, Lincoln, CA on Sunday, September 23, 2007

Crutchfield Customer Review (What's this?)

The only reason I didn't rate this as a 5 is because I have only had it installed for 1 day. The installation process was fairly easy (after reading these reviews) I tried to take a short cut and not cut/splice the XM data line but that caused the XM signal to be played in addition to the ipod signal. So I cut/spliced the cable (easily found behind the glove box) and all is well.

2003 Chevy Tahoe with Bose in Dash 6CD Changer, XM and OnStar

Written By Gregg, ny state on Thursday, September 13, 2007

I opted to have the unit professionally installed for the sake of time, and I am very happy with it.
Sound quality is superb and I have it hooked up to the XM1 band and set for hybrid mode(this allows playlist and direct mode via ipod controls). Similar to James, Edinburg, Texas on August 17, 2007 review, ..random works but if you try to "skip" to the next random song it goes back to playing songs in order. Song titles display in a non-scrolling manner on the radio display, and if you press info you can get the artist as well.

as a quick tip...the 3-4 buttons on your radio will be the rew-ff control in XM mode, respectively. Hit the button once and it goes into REW(3) or FF(4), hit it again and it goes back to normal play.

If you pick shuffle from the ipod controls you will get true shuffle play..if you want to "skip" a song, use the ipod buttons not the steering wheel controls or radio controls, and you will still be in shuffle mode.

As I mentioned, sound quality is truly stunning and I am delighted to be able to play my ipod on my Bose System. I highly reccomend the PA-11 and suggest you connect it in the new hybrid mode for the best of both worlds!

03 Tahoe Tips

Written By Dan, Austin, TX on Tuesday, August 28, 2007

Crutchfield Customer Review (What's this?)

My advice is to remove the a/c head unit in addition to the radio head unit. This will give you additional room to manipulate the wiring harness behind the radio. In my case, I could not remove the radio without this step; however it proved to be very beneficial when reinstalling the radio with the additional harness attached. As other reviewers stated, it is a very tight space when pushing the unit back into place. My solution was to move the Tahoe's factory 12-pin connection and the PA11's radio hookup behind the rear metal backstop in the empty cavity to the left of the unit where the 24-pin factory connector was located. Thus all original and add on wiring was in the deep left cavity, allowing the radio head unit to slide right into place.

Also, I mounted the PA11 unit in the cavity to the bottom right of the cavity under the cubby hole (to the right bottom of my a/c headunit and in between the glove compartment and directly behind the console). I used double sided foam tape to secure the unit to the sidewall. Then I ran the iPod cable in between the console and a/c headunit in a space where the console meets the bottom part of the dashboard. There is a perfect gap even when the faceplate is reattached.

I chose the direct mode and it works great. I do no have an XM unit, so installion was a snap once I figured out the a/c trick. Good luck to all - this is a great device.

Sounds great but can't do Random in playlist mode

Crutchfield Customer Review (What's this?)

I was wanting to keep my ipod in the glove box and use playlist mode to access 4 different playlists or go to disc 5 and shuffle my entire lib. The random feature does not work in playlist mode, only in direct mode. By the way, I'm using the disc changer method. Well, I called USA Spec and they told me that they were having problems with the random feature and they didn't think it would be solved anytime soon.(software problem)
I'm surprised no one has mentioned this problem, or am I the only one?
Crutchfield has been great, and I may return this thing, although it does sound good.

2005 Chevy Silverado - XM capable but no XM installed - No CD Changer

Written By cduchon, Ohio on Tuesday, June 19, 2007

Crutchfield Customer Review (What's this?)

According to Cruthfield I would have to cut out the OEM mounting bracket to accommodate an aftermarket radio.

With that in mind I am very pleased with the PA-11. It allowed me to get iPod integration without modifying the truck.

If an aftermarket unit with built in iPod controls would have fit WITHOUT modifying the truck I would have gone with that option.


+ Easy to install, decent sound quality, price

+ Will randomly select songs from the entire iPod library

+ Displays Artist/Song Title on radio although it cuts both short on my radio and there's a slight delay while it gets the info from the iPod to the radio.

+ Has an option for Direct Mode where you can control "basic" iPod functions from the radio and still retain "full" control at the iPod. (No ability to show artist/title on radio in this mode)


- Only displays partial song title and artist on my radio

- Only displays songs in Playlist Mode.

- Playlists are played sequentially... no ability to randomize songs in a playlist (It will select random songs from the entire library though)

- There is no "easy" way to find a specific song unless you are using the Direct Mode and you search on the actual iPod.

Overall, if you want to retain your OEM radio and add iPod capabilities I would recommend the PA-11.

Vehicle....................2003 Chevy Silverado SS w/ Bose package and XM
Total Install Time....1 hour and 30 minutes

I purchased this item after having bad experiences with a variety of mp3 solutions over the past four years. Let me tell you, this does what it says, and then some!

Having popped the dash off numerous times, I knew the sweet spots so I didn't have the same problems a first-time installer might. Also, the harness was very easy to hook up because you couldn't get it wrong. The majority of the time was spent seeing my Dremel tool give its last gasps of breath (it has served me well) making a few holes in the cigarette lighter console for a nice, neat fit.

They even sent me an upgraded version for free. This upgrade gives you the "Hybrid Mode", which is like the Playlist mode described in other reviews/information, but you also have the power of Direct Mode simultaneously.

Sound Quality is digital greatness. iPod vibrates the mirrors when hardly turned up at all instead of on full blast with lots of static from a RoadMate.

I'd give this thing 6 stars if they'd let me!

Sounds great, and I can bring all my music with me...

Written By Anthony, Anchorage, Alaska on Saturday, May 26, 2007

Crutchfield Customer Review (What's this?)

I recommend reading ALL the reviews before purchasing or installing the product... with that said, like everbody else, the hardest part is getting the headunit back in because of the additional wiring harness.I used a small diameter cardboard tube from a laundrymat clothes hanger to guide/push the wiring harness in the direction I wanted it to go (the big harness to the left and the rest right). I used the direct mode, as it seems to be best suited for the intended use of my Ipod. I have an 2003 Avalanche with the premium BOSE sound system w/6 DisK CD and no XM or On Star, and there is not a whole lot of room behind the glove box, but thats where I mounted the interface unit, with zip ties to another wiring harness, until I'm sure it will work flawlessly. I also got the Pro-Fit grip mount and vehicle specific mounting plate, for the professional install "look", but it would be just as well sitting on the center console, if you'd like to save sixty bucks. The Ipod cable that came with mine, dosen't seem to go in all the way into the interface unit, which causes a poor connection and a channel to cut out occasionally, and I intend to ask for another on Monday.

Good Luck!

‘06 GMC Sierra 1500 Crew-Cab, factory AM/FM/1-CD/XM radio. My first recommendation is to print all of these reviews so you can reference them. The help from these other reviews was great, especially as far as the location of the XM unit - behind the glove box, as mentioned. Ill try not to repeat what has already been said. The R & R of the head unit was easy, even getting it back in was simple - just pay attention to wire-routing and take your time. I put the USA unit right next to the XM unit, and ran the iPod cable inbetween the console and the dash - just slid it thru the gap between the two panels, and let it sit on my center console. If any cables will POSSIBLY rub against any of the sharp metal edges present under the dash make sure you protect the wires with a shield of some type to prevent a future problem. My USA unit is easy to access if I want to change the dip-switches or add the RCA input - which you probably dont need. I opted for the "Playlist Mode" install, where you cut the XM wire. After doing this and testing it, I reset the dip-switches and now use it in "Direct Mode". I prefer this because it gives me much more control over the song selection - you still have full control independently over the iPod (to pick a specific song/artist/album/playlist/etc.), and you can still skip forward or backward over songs thru the GM head unit and/or steering wheel controls. Often Ill set the iPod on "Shuffle" and leave it alone and just skip over songs I may not want to hear. In Playlist mode, the only way I could “read the song info” on the head unit was by touching the “Info” button on the head unit

USA Spec iPod® Interface

Written By Sean, Durham, NC on Friday, March 09, 2007

Crutchfield Customer Review (What's this?)

This is exactly what I needed to interface my IPOD with the factory stereo in my 03 Silverado.

Be advised that you do not need the mini stereo to dual RCA cable. Music will play via the charging cable supplied with the kit. I wish I would have known this as it would have saved me 20$.

Out of the box,my 581PA11GM was set to display the Song info on the stereo but I didnt care for that to happen and I wanted to be able to change the song via the steeringwheel controls. This was accomplished by a simple dip switch change on the back of the device.

Bottom line... If you have an ipod and you want to connect it to your stock head unit, get this!

I'm sure you're wondering how it would work for you. The installation is very easy - the hardest part is getting the factory connectors apart, and that's not very hard! I have a 2005 Chevy Colorado, with no XM or CD changer. Pretty basic CD radio. I took off the trim panel, removed the radio, connected the wiring harness and the USA Spec iPod interface, and then checked it before reassembling the dash. It didn't work. I checked everything, and discovered I hadn't completely connected one connection. Check again, and voila! I've got iPod through my radio. For some reason, I had set it to see the iPod as the CD changer, but it came through as XM. No biggie. I reassembled everything, installed the bracket I also bought, and routed the cable. Once the dash is back together, I check again, and now the radio sees the iPod as a CD changer. Whatever - it still works great!

They gave great instruction on how to pull apart the whole dash for that install and I found a great place to mount the unit on a dash support beam behind the head unit.

Great product and a helpful install tip

Written By Matthew, Gaithersburg, MD on Wednesday, February 14, 2007

Crutchfield Customer Review (What's this?)

I highly recommend this product first and foremost. I have a 2005 GMC Denali. When I bought the truck, I tried to bargain with the dealer to install an Ipod adapter to no avail. I searched Crutchfield and sure enough they had what I was looking for in the USA Spec.

Removing the head unit is a breeze, like any GMC. HOWEVER, if you have XM PLEASE PLEASE PLEASE, make sure that when you remove the head unit, SLOWLY pull it out of the slot. Hold it just out of the slot, and look on the back. You will see a wire with what looks like a phone jack (its green) running into the back. TAKE YOUR TIME removing this chord. It is your XM/FM modulator, and you will not find this piece by itself anywhere. As I found it the hard way, I ripped the chord from the jack in my haste, and the whole wiring harness costs $700 to replace. You dont have to have it if you dont want XM or want to run the interface through your CD player, but as I found out, you will not have any bass if you run it through the CD player and the sound seems distant. The XM is the way to go for the best sound with the interface.

Putting the head unit back in is a bit tricky like all the other reviews will tell you. The big harness should be pushed back to the left. The little harness, connected to the thick chord running to the interface can be pulled from behind the glove box. Just take your time, I promise you it will work. After bending the wires to the aforementioned directions, all of a sudden it just fit for me.

Just be careful if you have XM, and enjoy. I was debating between this product and the others on Crutchfield and I am so happy I got this. It works great!!!! - M

Crutchfield Customer Review (What's this?)

This item was installed in a 2006 GMC Sierra 2500HD with a factory GM/Bose system with XM radio and in-dash 6 disc CD changer (built into the head unit). Since the CD changer is part of the head unit, I had to opt for the XM radio version of the installation. First, I want to say THANKS to the many reviewers that made note of the location of the XM receiver. There is no way I would have found it on my own. The easiest way to access it was to open the glove box, and release the door stop, allowing the glove box door to flop down. The receiver is on the right hand side, directly behind it. It is not labeled at all. It has a 12-pin connector, and a single orange wire going to it (presumably for the antenna).

As for the rest of the installation, it was as simple as plugging in the supplied harness in between the factory harness and the radio, and then routing the cables to the spot where you mounted the adapter box. I found and ideal spot just inside and to the right of the glove box opening. This makes it accessible if you need it, and all the cables are long enough. And soldering in the blue XM data wire was simple enough, but be careful not to cut adjacent wires (like I did). If you have trouble getting the head unit in/out, take out the heater controls below the head unit. 2 screws and it pops right out. Makes it much easier to get your hands in there.

I opted for using the direct mode. It works perfectly, sounds great, and the XM still works fine on the XM2 band. Get the Crutchfield recommended mounts as well. They work perfectly. This is a must-have item.

Installation in 2006 Envoy

Written By Daniel, Sterling Hts., MI on Sunday, December 03, 2006

Crutchfield Customer Review (What's this?)

Since I found previous reviews helpful, but not completely for my vehicle, here's my experience installing in a 2006 Envoy with Bose system, integrated 6 CD changer and XM. You cannot use the iPod through the CD with this system. I wanted to use CD so I didn't have to install the blue "data" line. Tried without first, but iPod would only play on top of XM2 so that I could hear both iPod and XM. Called Crutchfield Tech Support, who was very helpful. Because the CD is integrated into the radio, I had to go through XM and attach blue wire to the white XM "data" line in Pin 7 (not hard to find if you unplug from XM). XM receiver is in it's own panel under the glove box (only two screws to remove panel, two nuts for the receiver). The blue wire was not long enough to get to XM receiver, so I had to splice in a length because I put the adaptor by the radio.
Installation was pretty easy otherwise. Crutchfield instructions were very helpful. I did lose XM1 to the iPod, but I'm not a huge fan of XM anyway so just XM2 is fine with me. Running direct mode, works very nicely so far.

Disappointed in Playlist Mode Only

Crutchfield Customer Review (What's this?)

I installed my USA Spec PA11-GM adapter to a 2003 GMC Sierra truck with a GM XM Ready radio without an OEM XM receiver installed.

I am very disappointed with PA11-GM adapter because the playlist mode does not work as I hoped. My plan was to use the iPod as a disk changer hidden away somewhere and scroll thru the playlists from my steering wheel and see the song titles on the radio, WRONG. I choose the PA11-GM adapter because I have a Sirius FM radio that I move back and forth between my work truck and my personal vehicle. The FM Modulated Radio sounds like crap until I connect it to the Auxiliary Input of the PA11-GM adapter. It shows up as "P6 T0001", but I'm ok with that as long as I have quality sound without static.

The Crutchfield Tech Support was very helpful, in fact I think they were the best Tech Support I've had even though it was unsuccessful. Crutchfield immediately called USA Spec and returned back to me with some new information that made some progress, but I still don't have a song title or artist. It only changed the display info from "D1 T1" to "P1 T0001". Since I do not have an XM receiver I can't do anything with the data wire, although the Radio now shows the XM bands.

I should have just bought an Auxiliary Input Adapter for half the price and plugged in the iPod or Satellite FM Radio as needed. I will probably install an XM Direct Satellite Radio after my Sirius subscription runs out.

Crutchfield Customer Review (What's this?)

I installed this device on a 2006 Chevrolet Suburban with a factory 6 disc CD changer and factory installed XM radio. I had previously used an FM modulator and was very disappointed with the sound quality from that device. I can not imagine better sound quality possible from anything other than the PA11-GM.

The installation was not as difficult as I would have expected after reading these reviews. Getting the radio back in with the harness attached is a task. Dont get frustrated with this until you've worked at it for at least an hour!

I connected this device as instructed by the directions. It is important to decide what mode you wish to use during playback, ie direct mode or playlist mode. To use playlist mode you must cut and splice the data wire from the XM reciever. As you will read, finding the XM receiver and locating the correct wire is not an easy task. All you get from the playlist mode is that your radio will display the song title/artist. This display is not scrolling so you only see what will fit. If you put this music on your iPod, you should know what is playing anyways. Playlist mode does not allow you to access ALL your songs and is very disappointing. When I cut my data wire, some of the stations on my XM band no longer display the XM station name. If you use direct mode, you do not have to deal with your XM receiver at all. I verified this with the tech support people for the interface unit. I will soon be re-splicing my data wire back to the XM reciever.

This unit is a must buy if you want to use an iPod in your vehicle.

No Song Title Info on 2004 Yukon Denali w/Nav

Written By jgile, Green Bay, WI on Wednesday, November 01, 2006

Crutchfield Customer Review (What's this?)

I purchased this unit for my 2004 Yukon Denali w/factory navigation.

My unit came with a sticker that stated it supported song title information.

This unit will not display song info!

I had it professionally installed. The installer had some questions about the XM connection. We called USA Spec tech support. The guy denied that it could not show song information on my factory head unit.

Crutchfield Tech Support was great and shipped me a second unit, but this unit still doesn't show song information.

It also occasionally shuts off and requires disconnection from power. When this happen the XM receiver is disabled too.

This thing ROCKS

You have got to get this thing! The sound is incredible! Just like previous reviewers the Artist and Song Title will not display even though the instructions and advertisements say so. But don't worry, the sound quality is so awesome you won't care. I tried the Playlist mode but couldn't get the random mode of the radio to actually shuffle the songs. I switched to the Direct mode and the problem was solved as long as the iPod was in shuffle mode.

Just like others reported getting the radio back in is a struggle - about 1.5 hours worth of struggle for me. In the 2004 Tahoe you can remove the little cubbyhole below the center vent (just to the right of the climate control). Once that is removed you can reach through behind the radio and pull the wiring harness back as you slide the radio in. After many tries you can get it. Watch out for some rough edges - I came up with a number small cuts.

Simple to install, works very well

Crutchfield Customer Review (What's this?)

Absolutely love this device. Has revolutionized our car audio experience. Took about 90 min to put into our 2003 Yukon Denali with factory navigation radio. Radio was tricky to get back into the dash after the harness install, but that was expected because of previous reviewer's comments so I just took it slow and all went well.

It was actually harder for me to find the right location to mount the new interface box behind the dash. You have to find a location where cable length is not an issue for either the iPod cable, the splice into the XM box behind the glove, and the harness. I didn't want to drill it in anywhere so decided to use velcro to mount it near the XM box behind the glove. Then ran the iPod cable around the dash, and into the small hinged compartment next to the cigarrette lighter where I had drilled a hole for the cable (as another reviewer had suggested.) Very clean, cable stows away when not in use, can get to the box to change dip switches or add an AUX device down the road.

I'm NOT a car guy. I've never taken the dash apart before this. The instructions from Crutchfield and the advice from the reviewers on this site were extremely helpful and gave me the confidence to pull this install off!

2006 GMC Sierra 6 disc in dash, Bose without XM

Written By Jeff, San Francisco, CA on Thursday, September 14, 2006

Crutchfield Customer Review (What's this?)

It only took 30 minutes to install, works great in Play List mode or Direct mode. Play List mode is nice because it allows the simple use of Play Lists, but can be cumbersome to use. It does display Artist and title. I'm currently using it in Direct mode now, and find that easier due to my large number of songs on my iPod. This is the best iPod interface for a GM car or truck bar none. I've tried others that were real junk. This was very easy to install.

Doesn't deliver on it's promises

Crutchfield Customer Review (What's this?)

The product is good if your looking for a decent interface to connect you iPod and another auxilary device (XM Roady) to your factory GM radio. It sounds great. However, none of the great 'radio controlled' features promised work with my particular radio (2003 Suburban). All I can do is swap between 5 playlists (and the auxilary) and skip to the next/previous track. I cannot shuffle, ff/rw, or display the track info. Additionally, the connection to the radio gets lost frequently and I have to reset it. Crutchfield has be great trying to help me solve the problem - they sent me a replacement. The manufacture has offered to check the software upgrade, but I figure I should have gotten that with the replacement. Either it's not designed to work with my radio or support has not been able to help me figure out what is installed incorrectly.

I wish I knew about this product when I had my Nissan. Was so simple to install. Excellent installation manuals from Crutchfield! Sound is terrific. Controling the iPod is easy. Would recommend this over aftermarket radio and adapter.

Crutchfield Customer Review (What's this?)

before you buy this product realize that it only does as advertised. the hardest part is fitting the harness and receiver back into the dash of '04 tahoe. the ff seek within a track only works in random mode. I notice a high pitched noise in the background of playback. playlist mode is a deal breaker and a longer ipod cord & brackets would make direct mode more practical and safer. the best case scenario is that I still have my changer intact w/ the push of a button. this unit only works w/ the vehicle engine running. this unit would receive higher marks if direct mode functions were available w/ receiver control, the background noise issue and true ff and skip. Wait for better technology but if you need ipod in your car (GM) at the time this is the best offer.

iPod and XM SkyFi2 with factory Bose in 04 TrailBlazer

Written By Mark, Van Wert, OH on Saturday, July 29, 2006

Crutchfield Customer Review (What's this?)

2004 TrailBlazer LT EXT w/ Bose, internal 6 disc changer, OnStar, rear DVD.
Although Crutchfield advisor, Bill, warned that this may not work with my specific vehicle, he offered to let me give it a try. Hardest part of install was getting dash apart, installing power and antenna for SkyFi2 (didn't want to just plug into external 12V plug). The install of the USA Spec PA11-GM was easier than I could have imagined -- just unplug cables on back of factory head unit, plug into adapter, set couple dip switches per manual, and I had music from my iPod (and song titles displaying!). Pushed the button on the steering wheel a few times and, Presto, there was my XM from my SkyFi2.
I had tried FM modulators for the iPod and built-in one for the SkyFi2, but installing this adapter was like going from cassette tapes to CD in quality.
If this unit will work for your application, BUY IT NOW!!! Thanks for a great system CRUTCHFIELD!!!

(Please note that my vehicle does not have XM built in - not sure if this install would have worked if it did.)
