Select your car

Find what fits your car

You can take it with you! Just because you've got a factory radio in your GM 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 1994-02 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. The interface also 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.

2002 Silverado 2500HD

Written By Anonymous, Denver, CO on Thursday, January 08, 2015

Crutchfield Customer Review (What's this?)

No issues with installing this on my 2002 Silverado 2500HD with factory radio. This unit basically replaced the external tape deck that was in the center console (I also got the GM factory felt lined cubby from [offsiteUrl] to take the place of the tape player, part #15958735 for those of you who have the same tape deck and want to replace it with something useful). Despite what Crutchfield (and USA Spec) say, "The factory radio must have either a separate "AUX" or a separate "Source" button, not one button labeled CD/AUX," this does work with my radio that has one button for CD and AUX (CD is just above AUX on the button). Because my radio didn't come with an external 6-disc CD changer it doesn't have the icon on the preset 5 button for changing discs. However, pushing the number 5 preset button does change disc number for the USA Spec unit to know what I need it to do. I like the unit, does what I want it to do and would recommend this to anyone that wants to play through the factory radio without using FM transmitters or cassette adapters.

Pros: The Good: - Able to skip songs on iPod when connected through the 30-pin connection - Can connect what ever I want to the radio via the audio jack connector - Cheaper than aftermarket radios that can do the same thing (though an aftermarket radio can do a lot more obviously). Plus you can keep the factory dash look without ruining it with ugly aftermarket units.

Cons: The Not So Good: - It tricks the radio into thinking you have the external 6-disc CD changer. Each disc number does a different thing with the iPod (read the owner's manual). When changing disc number there is an annoying pop that comes out of the speakers. Not really loud enough to do damage, but annoying. - Must have the 30-pin to lightning adapter to hook up iPhone 5 and up - Would be nice to have an option to hook iPod/iPhone up via usb so you can charge and play with one cord

Got 2 adapters, both flakey. Avoid!!!

Crutchfield Customer Review (What's this?)

Have had a pretty horrible experience with this adapter, which I suspect is due to poor quality control by the manufacturer. The first adapter I bought worked well for the first few days but then the left channel audio started cutting out, replaced by a clicking sound. Crutchfield sent me a replacement adapter kit. I installed the cables and adapter, and found that the adapter software was very different than the software on my 1st adapter, which made it nearly unusable. I swapped in the 1st adapter and things worked great. I deduced the left channel issue was due to a bad cable. However, a month later, the left channel cutout issue is back and will not go away. I am going to rip out this stupid adapter and burn it.

2002 35th Anniversary SS Camaro Install

Written By Patrick, Fernandina Beach, FL on Tuesday, November 09, 2010

The install of this product on my camaro convertible with the Monsoon stereo was fairly easy with the instructions that came with the device. I found a way to conceal the device in the glove compartment, as it is said it was important to get to if I needed to reset it. All of the cords were long enough for me to route from the stereo to the box in the glove compartment back through my center console and up through the ash tray. Needless to say, it is fairly well hidden. I have seen a delay time between startup of the car and the syncing of the device, but it is no longer then a few seconds. The steering wheel controls work marvelously with my iPhone 4G. I found the best way to use it is put the CD changer to disc 6 which allow for hi-bred control, ie with iPhone and steering wheel controls, this allows me to pick the playlist and then cycle through with my steering wheel controls.

It is a great product and works extremely well.

USA Spec iPod® Interface for GM

Written By Anonymous, California on Tuesday, September 21, 2010

3 stars becuase of the price and my application. I had to order another adapter for my application and i did not use the radio harness that came with this product at all. So this much for a little white box and an ipod cable and another $30 for the cadillac adapter. If the radio harness adapter was removed and the price lowered to like $80 then it would have been 5 stars for me, but now i have an extra cable i can do nothing with.

Crutchfield Customer Review (What's this?)

2000 Chevy Blazer, iPhone 3GS

- It works--you can play audio, either from your iPod or RCA inputs, via your GM factory radio
- Cables supplied are good quality, they are also longer than I expected
- Unit is fairly small--fit easily into a spot behind my radio
- Configuration is simple--only via 2 DIP switches

- It's expensive vs. a new head unit--unless you really love your GM radio, think hard about this; there are a lot new head units that are available for not that much more money
- It pops--when switching "disks" there is a very loud POP from your speakers
- It's flaky--
*It takes 15-20 seconds to start up, and during that time your iPhone will flash between home screen and "accessory connected" and the display may go blank on the phone until you tap it
*It does something that makes your iPhone battery die faster... yes, it charges when plugged in, but after you unplug your iPhone it will consume battery 4-5X faster then normal ; if you power down iPhone and then back up after using this your phone doesn't discharge as fast ... I don't know why, maybe it starts up a background process that consumes CPU cycles and so runs down the battery, or maybe it gets the iPhone into a weird mode where it doesn't sleep correctly?

Because of the issues above I plan to abandon using the iPod cable with this unit and start using the AUX input connected to the headphone jack of my iPhone.

If I had it to do over again I'd have bought a new head unit

Not Compatible with 3rd Gen iPod

Written By John, Stoneham, MA on Sunday, June 14, 2009

Crutchfield Customer Review (What's this?)

The description of this adapter says it works with 3rd generation and newer
ipod, but below that in the actual list of ipods it supports, 3rd gen ipod is not

So I bought one anyway. It arrived and was completely whacked out. Nothing
would work. Crutchfield sent out a replacement, and the replacement worked
with a new iPod Nano, and an iPhone 2G. But it wouldn't work with my old
school 3rd Gen iPod. So Im returning both for a full refund. I'm not going to buy
a new iPod when this old one works perfectly fine. Car iPod sit in you center
console, you never even see them or touch them. So it's stupid to replace one
that's not broken. And it's actually very easy to replace the hard drive with a
larger one if this pod's HD every dies. So i'll likely have this iPod for... EVER.

This was an install for GMC Yukon XL with factory built in CD player and auxiliary tape cassette player. Unplugged negative from battery. Put on p-brake, put in drive to remove dash trim, pressed down plastic clips and slipped out radio. Unplugged wires in back of radio and plugged in new ones. Put the box in the glove and fed wires back through to the glove to plug in box. Easy as 1, 2, 3.

Good concept, but has bugs

Written By Dan, Austin, TX on Friday, July 11, 2008

Crutchfield Customer Review (What's this?)

'01 Tahoe, OnStar(deactivated), external factory amp, iPod Nano 3G
firmware 1.1.2; On first connect, USASPEC unit was set to Playlist mode,
and my factory stereo displayed "Err" after being on for around 20 seconds.
Unplugged everything and tried again, same result. Unplugged everything
again, switched to Direct mode, and everything works now. I have the Aux
In enabled and it works great too, but it did not work when the unit was in
Playlist mode. Note: The "Random/RDM" button on the factory radio will
cause weird things to happen. The end result of this product is good: I can
listen to my ipod through the radio with a clean sound connection, and i can
skip to the next song by pressing "Seek -->" on my factory radio. Picking
playlists and turning on random play must still be done directly on the ipod,
but I don't mind. Overall, I'm satisfied because I got it to work but I still
have a fear in the back of my mind that the unit will stop working one day
based on my experience with its bugs and based on other reviews where
people have said their unit stopped working. My car didn't have a CD
changer from the factory, so my stereo doesn't have the "Disc" label on
the "5" preset button. The "5" changes discs (which changes between
ipod and aux in) but I knew that because I have friends with GM CD
changers. The USASPEC manual might mention that "5" changes discs, but
I'm not sure.

Worke for a little while

Written By Ryan, Bay Area, CA on Tuesday, May 06, 2008

Crutchfield Customer Review (What's this?)

Really easy to install. Worked great (except for the RF interference was annoying on low songs) for about a week. Then the thing would only recognize the aux input and not the iPod. Which was great if i wanted to listen to my Sirius 24/7.

So I called the AMAZING customer care at Crutchfield.

They sent me another one out right away. Plugged it in and it worked great right off the bat

2 days later it died all the way. No input or iPod!!! All it did was flash the clock on and off. Couldn't even turn on the radio.

Just sent both back for a full refund. Thanks for the help Crutchfield, but the product just isn't up to standards of your company.

good while it lasted

Written By Jukka, Pittsburgh, PA on Saturday, April 12, 2008

Crutchfield Customer Review (What's this?)

Installing the USA Spec iPod interface was very easy. Hook up cables, and
securely mount the interface box in a convenient location. I was using the
interface with both my iPhone, and the AUX connectors, and found the head
unit integration reasonably good. The only, minor annoyance is how the iPod
cable causes the iPhone to suggest the airline mode every time it is connected.

Unfortunately, after using the inteface for approximately one week, it stopped
working for no apparent reason. The technical advice I have received has so far
amounted to, disconnect the cables from the interface box and try different DIP
switch settings, and later, disconnect the wires on the back of the radio to see if
that helps. Apparently these devices are known to randomly lock up, and in my
case, one can wonder if they simply are not rugged enough to withstand the
automotive environment.

Extremely Happy

Written By Derek, Tucker, GA on Wednesday, March 05, 2008

Just installed it in my 2002 Yukon XL, still can't believe how easy it was to install.
I'm very happy with Crutchfield for supplying the product as well as a breakdown
of my truck. Made it very easy to install the unit and get it up and running. I
drove around my neighborhood for a few minutes just randomly pulling up songs
to test it out. Thanks Crutchfield, you guys rock!!!!!

Works perfect. Exactly as advertised. Extremely easy to install - 20 minutes total. I bought the unit in order to utilize the AUX port with my cell phone/PDA MP3 player. Great sound. I also tested my son's IPOD. It's even better since the radio controls can operate the IPOD. I may buy an IPOD now......

2002 Chevy Tahoe, Cassette Player in Console, OnStar without Bose

Written By Sean, Pittsburgh, PA on Wednesday, December 05, 2007

Crutchfield Customer Review (What's this?)

When I called to order the PA11-GM45 I was on the phone for 10 minutes max, placed my order and received the product in the mail 2 days later. I pulled off my dash cover, clicked the radio out, unplugged the cassette connector, plugged in the cables to the back of my radio, plugged the cassette into the other connector, fed the wire down behind the radio and under the console cup holder. I took me maybe 10 minutes.

I used it with my wife's Ipod Mini and it worked flawlessly. I am getting the Ipod Touch for Christmas and I hope that it works just as smooth.

Seriously if you are somewhat mechanically inclined, this product can be installed from start to finish in less than 20 minutes. The hardest part was feeding the wire down the back of the dash.

Great implementation with a caveat

Written By erj, Scottsdale, AZ on Tuesday, October 30, 2007

This is why I ordered from Crutchfield... Received the iPod interface for my '02 Chevy crew-cab, installed it in about 15 minutes using the (mostly) excellent instructions. After giving my radio and the iPod about 20 seconds to sync up, worked like a champ, CD-quality sound, I love it! ... for about 3 weeks.

Then it started dropping either the left or right (or even both) channels of the output. Traced the problem to the box or its connections (the instructions said to keep it in a location where you can get to it. Glad I did!) When I would lose a channel I'd tap the box and it would come back immediately. Called Crutchfield tech support today, and they VOLUNTARILY suggested a replacement box be sent, gave me a RA number for my unit with instructions to send mine back when the new one arrives.

I wish all companies were this customer oriented! Will try to update when I get the new box, whether it solves the problem or not.

A few quirks, but still a great option

Written By Bryan, Denver, Colorado on Sunday, August 26, 2007

Crutchfield Customer Review (What's this?)

I installed this unit in a 1997 Pontiac Grand AM with Factory Cassette stereo, which was simple and straight forward. I have been using it for about 6 months. This review will focus on some quirks I've experienced and can reproduce:

1) Random mode will play a song at random, then a few seconds of the next song in the playlist, then jump to the next random song. This behavior is kind of annoying, so I don't use random mode.

2) Another quirk, if I don't drive my car for more than 24 hours or so, the stereo looses it's connection to the iPod and I need to physically turn the iPod on by pressing the center button. It's not that big of a deal, and I haven't invested any time to investigate how to resolve this.

3) Very annoying behavior related to using the RCA inputs. Connect a RCA to 3.5 mm mini plug cable, flip a dip switch and Disc 6 will play whatever you connect your line level input to. This option is perfect for an iPod Shuffle, or if a passenger wants to play DJ with the iPod in hand. The only drawback to this was the unit is extremely susceptible to what I am assuming is static discharge. If I would touch or accidentally brush my hand against the headphone jack connector's exposed metal connections, sometimes the interface would lock up and stop working. I would have to get under the dash and disconnect and reconnect the cable connecting the unit to the stereo to fix this. The manual recommends installing it in an "easy to get to location," in case you have to reset it, and I would agree.

USA Spec is a great product

Written By Scott, Denver, CO on Monday, July 16, 2007

Crutchfield Customer Review (What's this?)

I was tired of the RF "noise" when using my DLO Transpod - in general it worked well, but not enough volume, and always fighting radio station overlap. the USA Spec fixed all that - installed in 30 minutes (hardest part was pulling the cable up to the back of the radio - use a string & key and drop it down from the radio hole once the radio is out - then pull cable back up!) - the USA SPec box itself sits under the drink holder (pops out with a little pull - snaps back when you are done), and the cable comes out the side by the drivers foot (there is even a notch to feed the cable through). The only challenge you have is where to put the iPod - I liked the location of the DLO, but for this setup, you have to use a cup holder, or "manufactur" something to stick in your cigarette lighter. Those are all minor compared to the sound you get by pumping the iPod directly to the radio - I love it!! Now I want to upgrade all my speakers - the stock ones are sounding a little tired...........!

Crutchfield Customer Review (What's this?)

I have absolutely zero skills in installing anything and this product is a snap to do. It took 1 minute to get the dash cover off, 2 minutes to hook to the back of the car stereo and then 30 minutes to jam everything back in. It worked great from the beginning.

Only suggestion I have is to make sure you have it hooked up correctly before attempting to cram everything back in the dash.

This product is all it is cracked up to be.

2002 Suburban w/factory am/fm single CD

Written By Jim, Southern, Maryland on Saturday, June 23, 2007

Crutchfield Customer Review (What's this?)

Installed in less than 20 minutes. I interfaced the unit
with the "line out" jack of my Garmin Street Pilot 2730
GPS (also purhased at Crutchfield) using the aux jack. I have a GXM-30 XM Satellite antenna/radio connected to this GPS. I receive CD quality satellite music, driving directions, weather, and traffic alerts.
Device worked 1st time. Instructions that were provided were correct to the smallest detail. My major problem (about 15 minutes)was finding a place to work the radio to device cable through the dash to my mounting position. I have the ability to now connect an IPOD to the device with minimum effort.

Great Product that Gave life to my old factory head unit

Written By Night_Sailor, Easton Connecticut on Tuesday, March 06, 2007

Crutchfield Customer Review (What's this?)

My factory CD player started skipping. The ridiculous number of commercials on AM and FM meant constant channel flipping. So I decided to eliminate commercials from my life forever.

My factory four speaker head unit was loud and clean sounding but not easy enough to hook up using the Aux interface. It is VERY easy, if you buy this kit.

I decided to remove the dash panel and install the interface myself. Crutchfield's great Customer Support made this easy--without tools, it took 15 minutes. With practice you could do it in 5 minutes. Routing the cable down through the dash took most of the time. Everything snapped together in seconds. A screwdriver is only needed to mount the box, or you could use velcro or a couple of tie wraps to hold it in place.

My iPod car interface has transformed my life. I now have great sounding music and the well laid out factory CD changer controls make operating the iPod fun. I can skip ahead or behind ten (10) songs or one (1), and find any song I want in seconds. Printing out and numbering your playlist's make it easy find songs in a hurry. Eventually you will be able to memorize Disk and Track information to quickly find any song. I've read that newer XM radios factory heads will display the title and artist information. That would make the product perfect.

NOTE: My factory head unit is for a single CD-player. The unlabeled "5" button is used to change iPod playlist's. I labeled it so other drivers will know how to change playlist's.

Highly Recommend!

This product is great and with crutchfields easy to follow installation intructions I had it installed in 20 minutes start to finish. The product works great and the sound quality is second to none. I've had an FM transmitter and had all kinds of problems with reception and fuzzy songs. With the USA Spec interface there is no static and you never have to worry about changing the station or looking for a new one. I'd recommend this product to anyone who listens to their ipod in the car

Best on the market for factory head unit

Written By Christopher, Nashville, TN on Friday, December 01, 2006

Crutchfield Customer Review (What's this?)

Nashville - Music City... with all the radio stations around here, an FM modulator or transmitter is out of the question. So a direct connect was essential for my iPod needs. This product works great in my 2002 Tahoe. However it is not with out its limitations.

The good:
Excellent sound quality, very easy installation, works as designed.

The not so good:
A) When using it to control the iPod via radio buttons, you really have no idea what song is where, unless you have memorized your GM1, GM2, etc. play list.
B) Every now and then the iPod will not go to the next track, or it will skip a track when you press the next button... not an issue as pressing the next button again seems to take... guess you have to press it like you mean it.
C) Sometime it takes a minute for the IPod to load and the head unit to see the "CD iChanger". I've had to unplug and re-plug the iPod from the cable a time or two.

Over all I am very pleased with this unit... so much so that I purchased one for my brother and wife for their vehicles.

Installed it in a 97 Suburban with the large factory radio with casette, and the remote single CD below the radio in the dash. There is a 9-pin plug that connects into the back of the CD unit and runs up to the radio. When you pull out the CD unit you will see it hanging in the back of the space where the CD unit used to be.

This little device comes with a cord that plugs right into the 9 pin plug. I already had taken the dash apart and removed the remote CD unit when the device arrived in the mail, and it literally took about 40 seconds to hook up and start playing iPod music! Amazing

I don't own an i-pod. I installed this in my 2001 Chevy Blazer, in order to connect my laptop through the Factory Delco In-Dash CD Player. WORKED THE FIRST TIME! I installed it in the glove compartment with velcro. Took about an hour and a half, most of it being taking the dash apart. Didn't even have to select a track--as soon as I hit the AUX button, it activated the unit! WORKS WONDERFULLY, and NO MORE STATIC from the crappy FM Transmitter I was using!

Crutchfield Customer Review (What's this?)

This is a great product. Application for 1999 Tahoe. The Tahoe comes factory with radio/cassette and the CD unit is separate. I invested in a 2002 Tahoe radio that looks the same with the CD player in the radio unit (via ebay-cheap) and removed the existing CD player and bought the GM 'cubby hole' accessory which fits right in and adds additional storage in dash.

The entire application was super easy and the quality of the IPOD playing thru the radio (using Auxiliary setting) is awesome. If you are looking for a solution that will fit your 99, or later model Tahoe, this is it.

So cool to control your IPOD via your radio (fst fwd/rewind, next song/prior song, playlists/etc. Just plug in IPOD, throw it in glove box or console, and it is easy. Switch to radio and IPOD unit pauses/switch back to AUX and IPOD is starts....and it charges.

Well worth the price for a seemless solution considering some of the FM modulators are half the costs and half the quality.

Can run XM, ON Star and 6 CD changer with BOSE system in 05 Avalanche

Written By The Magician, Orange County, CA on Monday, June 26, 2006

Yes indeed, you CAN run your iPod, 6 CD changer, ON-Star AND XM radio without conflict!

After confirming this detail with USA Spec I ordered and installed the iPod interface without any problems... The XM-1 (band) now commands the iPod giving me only 6 pre-sets for my XM tuner on XM-2 (band). The package says that the USA Spec IPOD Interface WILL support artist and title info on the stock GM head unit, but I can't make that happen... I only get track numbers and playlist numbers...

You can also set the adapter via dip-switches to allow full controll of the iPod via the iPod's thumb-wheel or deal with "limited" controll over playlists using only the GM stock head-unit... The back-seat radio controller for my kids requires that I "boot-up" the XM receiver first to give them controll of the XM receiver remotely.

Think about it; You purchased an iPod because of it's ease of navigation and indexing and NOTHING can replace that in a head unit... I set the dip-switches to give me controll of the iPod on the iPod itself.

The unit is a bit "quirky" but the adavtages out-way the disadvantages!

I subtracted one star because of incorrect information in the manual and slow email response from USA Spec.
For my 2001 Pontiac Grand Prix GTP they say my radio has to be AM/FM/TAPE radio with AUX only.Slave unit must be disconnected. This is not true. It does require the radio that supports the external CD Changer. The changer is disconnected and the adapter works fine when you press the CD button. My radio was the single internal CD and that didn't work. I swapped it with the Delco Monsoon version that supports the CD changer.
It now seems to function as advertised and I'm using it in Direct mode. One thing I've found is that I can't put the iPod in shuffle mode. Not sure what's happening there. I'm taking a road trip to Michigan in a couple weeks and I'll give it a real work out. Maybe post another report. Have Fun. -phil

Outstanding Solution For Factory Radio

Written By Jack from Texas, Austin, Texas on Sunday, May 28, 2006

Crutchfield Customer Review (What's this?)

I always wanted to hook up my ipod to my Tahoe, and the first mistake I made ever was trying to use a FM Modulator for it. The sound quality was absolutely horrid and it was just awful to listen to. I searched Crutchfield and matched this interface for my Tahoe and ordered it mainly because I also wanted to keep the GM factory radio in there. When I got this item installation of it was absolutely easy, the only hard part of it was removing the radio and fitting wires back in but no problem. I also used the extra jacks on the interface to hook up a XM Satellite radio along with it so now I'm enjoying great sound from both through the radio with no unsightly wires running all over. This product is wonderful to just hook into your radio and you can also plug along with your ipod any other device ( DVD Player or Satellite Radio) and play through the CD Changer controls on the radio. This interface should have been my first choice for the ipod in my car through the factory radio.

Fantastic Product

Crutchfield Customer Review (What's this?)

Thisis a great product! I was using the monster FM modulator (with 8 preselected stations) and could not find a clear station to use. This little beauty makes my IPOD sound a 1000 times better. A big plus is that it has an auxillary input (for your portable satellite radio receiver perhaps?) or an additional item. I highly recommend this product.

Excellent Product, Excellent Value

Crutchfield Customer Review (What's this?)

Installed the USA Spec device into my 2000 Chevy S-10. I seldom bother to write reviews such as these, but it was such a simple install -- and to such good effect -- that I had to write in here.

Total install time was about 45 minutes, and most of that was wrangling with the awkwardly designed S-10 dashboard cover. Once I figured out how to lift that out -- thanks to the excellent Crutchfield-supplied instructions -- pulling the factory stereo, inserting the USA Spec cable into the unused CD-changer slot, and then threading the cable to the proper location were all quite simple.

On an older factory stereo such as mine, you don't get much by way of title display, of course. But you get good iPod control (FF, Rev, Skip track, etc.), CD quality sound--and an AUX line-in input if you decide to get an XM or Sirius receiver. Anyone with a qualifying GM setup would be silly to buy an expensive FM transmitter/charger system instead of this simple and elegant system. I replaced a Monster iCarPlay with this because the Monster picked up alternator whine from the GM electrical system.

USA Spec iPod® Interface for GM

Written By Anonymous, Las Vegas, NV on Monday, January 16, 2006

This is a great product for people who want to use their ipod with a factory radio and prefer the best sound quality they can get. It also allows you to use your factory radio and steering wheel controls to control your ipod. What makes this stand out from the other ipod interfaces is that it allows the option of direct or radio control of songs, adds rca inputs great for people who have a rear seat monitors, and also allows you to keep your slave deck in your gm vehicle despite what said in the description.

Crutchfield Customer Review (What's this?)

I was told twice if my radio didn't have the "SOURCE" or "AUX" button this unit will not work on my car. This is not true! The CD/PLAY button does the trick.

I have a 2001 Trans Am WS6 w/ the monsoon sound system. And this unit plugged right into it and started working immediately. The only trouble was at first was getting the radio out of the dash; and to solve this all i needed to do was to reach under the dash (by the gas pedal) and help the radio out by wriggling the wires in the back. The radio does come all the way out.

Oh by the way; it sounds awesome!!

Crutchfield Customer Review (What's this?)

After trying out a $100 fm transmitter and then only a few months down the line having it break, I decided that for nearly the same price I could have better sound quality. I installed this device into the glove department of my 2000 Chevy S-10 pickup. I have it setup so that I can use both the controls of my radio and my ipod. I like to know what song is playing so I mounted the ipod right next to my vents. This product works great and was easy to install.

Great Product, Better price than most

This adapter works great with my 2001 camaro w/ monsoon system. I like having control from the stereo/steering wheel, and from the IPOD itself. Install was a piece of cake, and by running the wire throught the center console to the storage box between the driver and passenger seats, the IPOD is secure and readily accessible, while staying plugged in. The price is much better than the competitors, with the same features.

great product, CD quality sound. All the controls work great such as track up and down. I would deffinately recomend this product. very easy installation. The only downside is that sometimes it doesn't charge. The problem is simply solved though by disconnecting the ipod and reconnecting it.

  • *Requires Apple Lightning to 30-pin Adapter (472LTN230P, sold separately) or cable (472LT30PAD, sold separately).
  • Apple iPod/iPhone software updates may change functionality results. If you download a newer software version, you may need to reset the head unit and your iPod/iPhone to regain functionality. If this doesn't work, you may need to wait until a newer software update is available.

Control Modes: The iPod interface adapter features the following control modes.

  • Playlist Mode: You can create up to 5 favorite mobile playlist then use your radio's CD changer controls to access and control your playlist.
  • Direct Mode: Gives you complete control of your iPod while it is connected to the factory radio. Your iPod is not locked out while connected to the radio and you are able to manually access your complete iPod content. The Radio still can adjust song up/down random or shuffle play but you can manually control your iPod and select any playlist, genre or Artist of your choice.
  • Dual Mode: Combines features of Direct Mode and Playlist Mode. You can create and access your favorite mobile playlist or directly access all your iPod content manually on your iPod. Your iPod displays song title information and iPod is not locked, so the iPod can be operated manually at all times. (May be referred to as Hybrid Mode in some manuals)

App Streaming (in Direct Mode): Direct mode also lets you listen to the sound from your iPhone's downloaded music apps (such as Pandora, iHeart Radio, SiriusXM, etc.) through your factory head unit & speakers. You will continue to control your iPhone's apps & view song/artist information from its touchscreen.

Note: Your iPhone will need an active Data Plan account with connection to the Internet via 3G, EDGE, or WiFi. You will also need applicable music service accounts.

Playlist Names: In order for the adapter/factory radio to recognize a playlist, it should be named GM2... through GM6... Text can follow the GM name and number, such as GM4_artistname or GM3-jazz. For a given disc slot (2-6), if there is no playlist named GM followed by that number, that disc slot will play the first available playlist on the iPod (the second blank slot will play the second available playlist, etc).

Auxiliary Input: In addition to the iPod input on the PA11-GM45 there is an auxiliary input (RCA) for use with another source, such as a DVD system, satellite radio, etc. The aux input is accessed at disc 6 track 1 using the factory radio controls. This aux input can be used with or without the iPod connected.

Playlist Mode Controls: In Playlist Mode the iPod is controlled using the CD Changer commands on the factory radio. Use the Radio's Disc Select controls to access the 5 custom mobile playlists, the Play All mode, or the auxiliary input. Track select, forward and backward, works just like on a CD. Other commands include shuffle play, scan (plays first 10 seconds of each track), Fast Track Search (skips forward or backward 10 tracks), and Fast Forward/Fast Reverse within a song (available in shuffle mode only).

Battery Charge: The PA11-GM45 charges iPod battery when connected. Charging stops after 1 hour of non-use to prevent draining the vehicle's battery.

CD Changer Port: The adapter uses the factory radio's CD Changer port so if the vehicle has an existing outboard CD Changer it must be disconnected.

Pause: When a non-iPod source is selected on the radio (AM/FM/Cass/CD) the iPod pauses.

Resume: If the iPod is not disconnected after use, it will resume playing where it left off when you restart the vehicle.
