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 or iPhone® (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 rear of your compatible 2000-up GM factory radio — you won't have to disconnect your CD changer or satellite radio. Plug your iPod into the interface, and you can control volume, source, song selection, and up to five different playlists right from the radio or with your steering wheel audio controls. Or you can switch to "Direct Mode" and use your iPod to access all your songlists. The interface charges your iPod while it's connected.

Crutchfield Customer Review (What's this?)

Good product easy to install and does what it says it great with I-phone 5s, but haven't tried with I-pod as yet.. Install was less than 10 min, hiding the wires took the longest since I am particular as the way things go and the appearance.

Pros: Great customer service from USA spec regarding the set up on the switches on the back of the unit..

Cons: instructions are clear as mud regarding the toggle switches on the back of the unit and wires needing to be used..but see pros for the good stuff

I wish I would have purchased this years ago...

Written By Curtis, Casper, Wy on Friday, May 22, 2015

I wish I would have installed this years ago! Being a Denali with navigation and DVD integration, adding ipod integration was limited; until i found out this existed. Easy to install (about a half hour), and super easy to use it is a great investment if you have a large amount of music on your phone like I do. I installed this almost a year ago and have had no issues with the exception of having to reset it one time as our XM quit working. Other than that 1 issue (glitch?) it has been wonderful. Also, it seems to work with all models of iPod / iPhone that we have tried. We have a range of iProducts from 2nd gen nanos up to iPhone 6s, and it charges them while you use it! Note: if you plan on using this with a newer lightning port product, you will need a 30 pin to lightning adapter (be sure it has music/video capability as the cheap ones do not, they are charge only). Overall great product, would Definitely buy again!

Pros: Charges iPhone / iPod, Easy to use / install, steering wheel controls still work, does not interfere with factory radio / dvd

Cons: occasional reset, you will lose 1 bank of XM presets as this will now take the place of XM1.

Very easy install. Literally plug and play.

Good sound, intermittent connection

Written By Casey, Satellite Beach, FL on Saturday, January 25, 2014

Crutchfield Customer Review (What's this?)

Nice looking, sturdy metal device. Easy hookup, and I appreciated the inclusion of extension cables to make it easier to find a suitable location to tuck the device away.

Sound is crystal clear. I've had other iPod / satellite radio adapters in other cars, and this one's sound is far and away the best. Track info comes across the radio's display whether I'm listening to tracks from an iPod or iPhone or streaming from Spotify.

Huge negative is that the device will intermittently lose it's connection to the audio system. No rhyme or reason - sometimes it will happen multiple times in a short trip, sometimes it works for hours with no hiccups. It's not losing connection with the iPod - you can tell by the way the display behaves. Happens on everything from an old iPod classic to an iPhone 5 (w/ official Apple adapter). Not annoying enough to go through the trouble of yanking it out, returning, and putting something else in, but if I wouldn't buy this again for another car.

Pros: Nice construction, extension cables are a nice bonus, great audio quality.

Cons: Intermittently loses connection, cutting off the audio for ~5 seconds and ruining your favorite song.

Ipod interface

Written By Tony, Idaho on Saturday, September 21, 2013

Crutchfield Customer Review (What's this?)

Plays the ipod music just great. Running the playlists through the factory radio is a little slow and cumbersome, but in direct mode it works great. I wish you could switch from direct mode to playlist mode so the names of the songs showed up - but when I do that it switches songs and takes me out of the artist I was listening to in direct mode. Its nice to have the iPod/iphone listening capability!!!!

Pros: Plays the music well - sounds great. Love it in Direct ipod mode.

Cons: Kind of slow and hard to find a specific song in playlist mode or any other mode that works via the factory head unit.

Works great!

Works great with my 2006 H3

Written By Cosmo, Silva Bullet Ranch Rocksprings TX on Friday, August 30, 2013

Crutchfield Customer Review (What's this?)

I ordered the PA15GM for my H3. The OEM{Monsoon} radio in my H3 looked and performed great, and I didn't want to change the look. This product was a perfect fit for me. I choose to hook up to my XM receiver, which was located above the glove box. When I was done, I just pushed it back into place, with a snap. I just removed the glove box lid, and pulled down on the top and the XM receiver was exposed. The connections fit perfectly. I put the module underneath the radio by pulling the center console out by inserting my fingers into the cigarette lighter and pulling, It popped right out. I then ran the "charging" cord along the drivers side door and up to the windshield where I mounted a suction cup cell phone mount attached to the glass. I ordered a marine type aux. input out of Amazon and attached it to the RCA outputs on the PA15GM. I mounted it through the ciggerete lighter {H3 has two} and it looks really professional. No exposed wires for me. This product works great. Does what it says it will. For my particular set up, DIP switches 1 and 4 are the setting I used. The whole setup looks great and this coming for a guy who knows absolutely nothing about car audio. The whole thing took about 1 hour with snaking the wires taking the longest. I've had it installed in my H3 for almost a month with no issues.

Pros: Installs easily, does what it says it will.

Cons: None as of this review.

Written By Colorado_Reviewer, Denver, CO on Monday, July 08, 2013

Crutchfield Customer Review (What's this?)

I installed it on a Chevy Silverado with the Bose XM option. It took less than 20 minutes. Simply pressed the glove box a bit to allow it to swing down lower, disconnected a connector and inserted the harness for this device between the two separated connectors. The only inconvenience is that the IPOD Playlists it can access are restricted. So, it is desirable to set up your IPOD so that the music you wish to listen to are located at the top end of your Playlists. The sound quality is excellent and the device allows you to use existing XM and Chevy radio controls. I recommend the device..

Pros: Ease of install and sound quality.

Great product. Works as advertised.

Written By Tsquare, Ashburn, VA on Monday, July 08, 2013

Crutchfield Customer Review (What's this?)

Received the item in 1 day (as always!) from Crutchfield. Hardest part of the install was finding the XM receiver in my vehicle (2006 Chevy Colorado). It was not located where the instructions that came from USA Spec indicated. Turns out it was behind a drop-down plastic panel on the passenger side of the truck near the center of the dash. The panel is attached with two clips towards the firewall side of the panel, and just swings down out of the way. Once I found this, it was a 10 minute job. Sound quality is awesome, and all the controls are via the OEM head unit. Definitely worth it if you want to retain your factory stereo and have iPhone/Pod capability.

Pros: High quality cables that plug straight in to the head unit. Very simple installation. Awesome sound quality and good integration with the factory controls. It comes from Crutchfield - what else would you expect!

Cons: Instructions could have been a little clearer on the specific connection location for my vehicle.

I love this interface! It maintains all stock functions, and gives you so much! I love the user friendly settings/functionality of this unit! Installed in my 05 Sierra in 20 min! All iPod info of displayed on stock radio and steering wheel buttons operate it too! (big bonus for me). But best of all is the iPod direct feature, where you use the iPod as if it were mobile, allowing you to play games, browse internet while still listening to music through my truck! This product is the best!

Pros: IPod direct mode, maintains ALL stock features, super easy install.

Cons: A bit spendy but well worth it!

This was a super easy add on to 2005 Avalanche with the Bose system with XM. I didn't want to swap my stereo so this was a perfect way to get my mp3 music available and was super easy to install, especially if you have the XM receiver built in.

Pros: Easy installation, high quality components

Cons: A little pricey, some of the navigation through your iPod folders is confusing but that seems to be typical

Worked as good as Addvertised in my 07 Chevy Classic with factory XM! Read over the instructions and after setting the DIP switches it took a whole 5 minutes to install! I just left the unit and wiring in the glove box, set it to direct mode and the ipod to shuffle. I never see my ipod or any wiring. Sterring wheel controls work great!

Pros: SUPER EASY INSTALL! The hardest part was unplugging the factory XM unit.

Cons: None that I encountered.

Crutchfield Customer Review (What's this?)

The adapter works just like it should. I was able to install it and have my dash back together within 45 minutes. The sound is amazing through my bose speakers. Even better than my cd player. I like the fact that I can still use my steering wheel controls and be able to display the songs on my existing stereo.

Pros: installation is easy using the existing connections without having to cut any additional wires. instructions are clear and easy to follow.

Cons: none.

Slick device (2003 Avalanche, Bose, XM)

Written By Jason, Minneapolis, MN on Tuesday, May 15, 2012

Crutchfield Customer Review (What's this?)

Since I had a factory-installed XM receiver, installation was really easy. Once I understood exactly what I had to do, it took less than five minutes to plug everything in for testing with my iPhone. It took me longer to run the cables back through the dash and figure out where to store everything than to actually get it working. Sound quality is very good and everything (including the controls on the steering wheel) seems to work. Plus it charges the phone at the same time, which I wasn't expecting for some reason.

The one nit I have is that it doesn't seem to reliably pick up whatever the most recent thing played on the iPhone. This might just be something I need to work through the details of; I tend to play a lot of sound through things other than the iTunes app (e.g. Audacity, iHeartRadio) and that might be part of the issue). Even if I can't figure out a way around it, it's not a big deal; once I switch to preset 5 to get control back to the iPhone it's just a couple of button clicks.

Pros: Easy installation, good sound quality, preserves all existing stereo controls.

Cons: Doesn't always remember what was just playing upon a disconnect and reconnect.

Nice to have iPhone working on my 2004 Tahoe, music sounds fantastic!!

Pros: Music and Navigation work great thru factory radio. Music turns down when giving turn by turn directions and returns to original volume.

Cons: iPhone calls do not work thru Tahoe speakers must pick up the phone, illegal here in MD if driving. It does turn down the music for you.

Sounds great

Crutchfield Customer Review (What's this?)

Received my order this afternoon and had it installed in under an hour. The sound is great and it works as advertised. My Tahoe has the XM receiver behind the glove box so installation was easy. It took longer to decide where to run the iPod cord. The plug on the cord was a little large and I wound up trimming the covers on the phones to make it easier to connect.

Pros: great sound, like the control options

Cons: would like a plug that works well with phone cover

Well worth it

Written By FredM, Charleston, SC on Wednesday, February 22, 2012

Crutchfield Customer Review (What's this?)

Does exactly what it claims to do. I decided a while back to replace the head unit on my 2004 Avalanche, thinking a "modern" system would be superior. I realized that what I really wanted most was to have access to my music collection, contained entirely on my iPhone. The factory system sounds great. Replacing the head unit requires an adapter to ensure that the vehicle's safety chimes function. This iPod interface was the right product for my needs.

I'm glad I read the reviews before attempting to install the unit. A most helpful tip was to READ THE INSTALLATION INSTRUCTIONS COMPLETELY before starting the work. In my case (Avalanche), there is no need to remove the radio or even dash. The instructions tell how to set the small switches on the unit before installing. The settings will differ depending on your display and operation preference.

In my case, the unit is connected into the XM receiver. Again, thanks to the instructions provided, I knew that the XM receiver is in plain view behind the glove box. Merely pressing in the rubber catch inside the glove box gives complete access. The supplied connector is identical to the factory connector, so there is no way to mess up the connection. I spent about 15 minutes at the kitchen table studying the install instructions and setting the switches on the unit. Once in the truck, it took literally five minutes to hook up the unit and run the iPod connector cable to an inconspicuous area of exit under the dash. Cool!

Pros: Easy installation. Uses existing stereo, gives full access to iPod/iPhone music collection. As good or better-than-CD sound quality. Can use factory steering-wheel radio controls to advance. Song info shown on radio screen. Still able to use factory XM radio.

Cons: If you choose to use the setting which gives full control to vehicle radio buttons, the iPhone/iPod does not display music info. Likewise, choosing complete control from iPhone/iPod disables some control via the radio buttons.

Crutchfield Customer Review (What's this?)

I had a number of problems with the unit. First, a number of people commmented on the difficulty of mounting this unit; they are correct. The adapter harness is only about 6 inches long and it was very difficult to find a suitable mounting location(I never really did)in my 2006 Colorado that didn't interfere with the factory radio. I also had an intermittency in my unit that caused the entire audio system to shut down after about 30 minutes of the playing time. Note that it shut down the whole system and not just the iPod. I checked the connections several times before removing and restoring the factory connections. I also found the iPod controls to be be confusing. (Note, Crutchfield offered to immediately replace the defective unit, but given I had already had the dash apart several times mounting and debugging this unit and didn't really like the controls, I declined.)

Pros: You can play your iPod through the factory stereo

Cons: Unit was difficult to mount Unit was intermittent iPod control was confusing

Crutchfield Customer Review (What's this?)

Very easy to install. There is NO wire cutting or splicing involved! Plug in and go!! I have an 06 GMC Sierra, w/o cd changer or xm, my factory radio recognizes my iPhone 4 as either XM radio or a cd changer (optional during installation), charges my phone at anytime as long as it is plugged in, I can control my iPod using my steering wheel controls, on the factory radio, or directly on my phone. The sound quality of my music from my phone playing over the radio is crystal clear and it gets as loud as i want it (unlike with the tape player with a cord plugging into my phone which made Lady Gaga sound like she were on a cassette tape). I feel like they thought of everything with this product!! Now I feel like my factory radio is somewhat up to date for 2012 and my truck is actually worth something.

Pros: SUPER easy to install, even easier to use, very very great to have with my iPhone

Cons: I honestly can not think of any cons

Good and Bad, 2008 Envoy-Denali

Written By Dan K., Milwaukee, WI on Tuesday, January 31, 2012

Crutchfield Customer Review (What's this?)

The install went okay once you know how to do it. My SUV has the XM hookup so you need to get at it from behind the glove compartment and remove the 2 screws to get at it. Attaching the adapter and running the cable went easier. It uses one of the 2 XM bands and the one it uses displays AUX. I do not know if this is common but my both my XM radio bands (XM1 and XM2) go into AUX mode after different periods of time and the XM receiver no longer plays. Sometimes it is months others a few days before it does that. I found by pulling the fuse that handles the radio I am able to reset the radio and the XM radio works for a while after that.

Pros: Easy install if you have XM radio. Pandora can stream thru it and display song info as well as music on the iPhone 4.

Cons: It streams iHeart radio but when switching stations it defaults back to the music on the iPhone until the next station loads. It would be better if it would just stick to the app when loading.

I-Pod Interface 2006 Silverado

Written By Felix, New Lenox, IL on Sunday, January 29, 2012

Crutchfield Customer Review (What's this?)

The I-Pod interface works great on my 2006 Silverado. Installation instructions were excellent. I did not have the XM module behind the glove compartment, so you need to remove the radio to install the wire harnesses provided with in the package. Still the installation was relatively easy. I suggest leaving the interface module accessable until you have used the unit for a while and figure out your prefernce for I-pod/I-phone connection cables.

The sound quality is awsome, and the interface allows I-pod control from your radio buttons. Much more convenient/safer than operating your I-Pod while driving.Much better quality than the wireless interface I was using before. I also purchased a blue tooth that plugs into the cigarette lighter which gives me hands free phone operation that plays through the radio.

Pros: Easily installed, clear and detailed installation and set up instructions, excellent sound quality.

Cons: The unit quit working entirely after two weeks. Crutchfield tech support had me unplug the unit and recycle all the dip switches. Crutchfield support is excellent. Anyway, the unit started working again and I have not had any other problems since. Working OK for about 4 months now.

Awesome Product

Written By Matt, Uxbridge, MA on Sunday, January 29, 2012

Crutchfield Customer Review (What's this?)

I installed this in a 2006 GMC Yukon Denali in about 20 minutes. Make sure you read the directions since it should be connected at the satellite receiver side of the XM cable and not the stereo side of the cable. I brought this to a dealer to have it installed and they didn't install in correctly (they used the CD hookup instead). While the interface was okay in that configuration, it is far superior to hook it up via the XM interface. With the XM interface the song, artist, and track all display. You can control the iPod from the touch screen, selecting playlists, artists, albums, etc...

Pros: Nice touch screen interface utilizing the existing XM interface on the navigation system. Sound quality is great. iPod can be hidden in glove box. Sound quality is great. One of the modes is "Direct" mode which enables you to still use the iPods controls. This lets you use other applications like Pandora. Also, when in that mode, if you are still using the iPod music app then it is controllable by both the iPod and nav touch screen at the same time.

Cons: The touch interface is a little sluggish when moving between playlists, artists, albums. It seems the first song has to start playing before you can proceed to the next list. No graphics are display - this isn't a deal breaker but it would have been nice.

Just not woth it

Written By Bob, Knoxville TN on Thursday, January 12, 2012

I was so anxious that this product was going to work on my 2003 GMC Sierra 2500HD. The install was as easy as it could be, little confusing in terms of how to set dip switches but got that figured out. Got everything wired up and back in place (made sure I could get to control box easy). After the hard install my hopes for a great product quickly dissappeared. Day four after the install I came out to a dead battery, I did not drive it day prior (lights were not left on, recharged battery and all well again). Crutchfield issued a RMA and sent a replacement due to a possible defective interface. I just swapped the electronic box and gave it another shot. The music plays great and you can control everything by the radio or steering wheel. The issue is I want the iPod to play random all the time. I have a iPod classic with over 16k songs and I do not want to select certain music. This unit will not do this, you have to select functions every cycle if truck sat for over an hour, it does not retain functions in memory such as random or direct mode. Everytime you start the truck the function resets and sometimes resets the whole iPod thus your greeted with the same song again. I called USA Spec and they confirmed that is how it is to function. Had I known that I would not have wasted my time. Thank you Crutchfield for alllowing me to return this for a refund. Just wish a little more R&D and voice of customer went into the design.

This product went together just as written in the book. The manufacturer gave me all the information I needed to find my XM module to hook up to. A little time planning this installation, and it all came together without a hitch. I like how you can press "5" on your radio and maintain control of your iPod,for instance when listening to podcasts, or let this unit control it. I've recommended this unit to other folks and wouldn't hesitate to purchase another unit.

Easy Install in a Tahoe. Works Great.

Written By PowerSurferNJ, NJ on Sunday, October 09, 2011

Crutchfield Customer Review (What's this?)

Would recommend this to anyone with a GM car that this fits.

Easiest install I've done, of about a dozen installs over 35 years. The Tahoe dash came apart easily, the connectors all fit perfectly. I was able to snake the wires exactly where I wanted everything.

Since the adapter works with a lot of factory radio variations like XM and Nav, you have to read the manual very carefully to figure out which section applies to your setup. I found final configuration a little confusing so I called Crutchfield Tech support. The technician quickly understood the problem and walked me through the final setup. With a flick of a dipswitch and resetting the system everything worked. Factory radio and steering wheel controls all work as designed and described in the manual.

The sound from my Ipod is brighter than playing a CD. Depending on your taste, minor tweaks of the treble/bass (or ipod EQ) may be required, depending upon the music.

The only other comment is that the adaptor box has no flanges, brackets or holes to secure it. I hid it under the cupholders, which lift right out of the Tahoe's console, making it readily accessible. I'll probably use velcro to secure the adaptor box since it's light.

Crutchfield Customer Review (What's this?)

The install was pretty easy, hooking it up to my factory satellite module behind my glove box. So you know, the iPod function replaces all your XM1 and you only have your 6 XM2 presets to use. After I installed it when I listened to XM it has a very annoying static in the background. Forget listening to talk radio it sounds terrible.. The iPod function worked great. That right WORKED great. After about a week it has completely stopped working. Oh yeah one more thing on a regular basis I would have to power off and on the radio to get it to pick up onany signal. Good idea but the product is junk.

All I have to say is WOW! Installation was ten minutes, out of box and into vehicle (2004 Yukon Denali). Great sound, no static. Took a little more time, maybe 15 minutes to comprehend the display functions on my screen but all in all great product. I have a Lexus GS400 also, I wish they made an interface for it as well. Thumbs Up

Just Awesome!

Took me longer to read included instructions than to install. If you read and pay attention you won't remove the radio if you don't have to, NO power or grounds to chase, just plugged it into sat. box behind glove box ran wire where I wanted ipod to go and Ipod rockin!! 10 minutes tops. Most incredible car audio product I've ever installed. Steering wheel controls and sound quality tops! Used double sided foam to mount. Only thing I would add is, removable mounting tabs but ty straps work too. THANX!!!!!!!!!!!!!!!

I had to send it back to USA SPEC to get a software upgrade. I had to pay shipping 1 way and it was kind of a hassle dealing with their preapproval prosess. Other than that I love it.

Received this afternoon and had it installed in my '05 Suburban (factory stereo +DVD +Nav) in about 1 hour. Cable connection to XM stereo took ~5 minutes, remainder of time was spent routing the iPod/iPhone cable through dash. I drilled holes (1/2 inch), 1 in dash and 1 in bottom rear of glove box, to hide the cable. Works great!

fantastic. did exactly what i wanted. installed it in my 2005 h2 (very easily i might add) using the cable that went to my sat radio receiver which is mounted right behind the glove box. i can now see what is playing from my ipod on the touch screen. can change playlists right on it. can skip songs with my steering wheel controls. excellent part, as usual, from crutchfield.

Works, pricey

Crutchfield Customer Review (What's this?)

An easy way to get an iPhone working in my 2004 Tahoe (with factory XM). Install literally took about 10 minutes, took much longer to route the iPhone cable somewhere hidden.

One disappointment, if you use 'direct control' (where you control playback with the iPhone, rather than using the factory radio controls), you don't get anything on the display of the radio, only on your iPhone. No HUGE issue, but too bad.

The price is pretty steep, but not many alternatives right now.

Would recommend to everyone

Crutchfield Customer Review (What's this?)

This is the perfect addition to my 04 Silverado. I already have the Bose sound system from the factory and I didn't want to install an aftermarket head unit because I like how my factory unit matches the interior perfectly. This was the perfect option for hooking up my iphone and since it uses the ipod dock connector, it sounds much better than my wife's bluetooth sync system in her Ford. The music sounds perfect through the bose speakers and it only took a few minutes to install. I drilled a single hole (optional) through the tray by the cup holder for the cord. And I removed the rubber tray insert prior, so that if I ever remove the ipod cord the insert goes back and covers the 1/2" hole completely. Great purchase, works exactly as advertised, simple installation.

Easy installation and sound quality is great! The only hiccup is that
the "shuffle" setting on my Ipod Classic gets turned off everytime I connect to

feature. Only a slight inconvience and well worth it to have premium sound!

This product works great! the only little complaint I have is that I wish it had a longer
cable that plugs into the back of the stero if it would have been a few inched longer It
would have been easier to install. I do not have XM so I had to plug itinto the back of the
radio and it was difficult to finds a good place to install the box. Other than that it works
great just like it said!

Crutchfield Customer Review (What's this?)

Purchased and installed without a hitch.

Produuct arrived the following day (24hrs) on my door step.

I initially found this product to be overpriced for some cabling and plugs,however, I have
purchased and installed items from Crutchfield previously and found the product and
instruction packet to be dead on as described. So I went for the reliability of Crutchfield
and willingly paid for their experience.

The instructions lead me to believe I would have to disasemble the dash and remove
the radio and also make access to the XM box. I did so without any problems, simply
followed the instructions provided. I did find that it was not nessasay to remove the
radio though, the connections were performed at the XM Box.

One dissapointment is that once I plug the IPod into the cabling ,I lose the use of the
IPod screen and using the radio controls are not as easy as the touch screen on the

Works great 2004 chevy suburban (bose, indash cd, xm, onstar)

Written By DM, CA on Sunday, January 09, 2011

Crutchfield Customer Review (What's this?)

Works great! 25 min to get plugged in and functioning.

The hands on research on the main PA15-GM page indicates this unit does not work
with the 6-cd in-dash changer of my 2004 Chevy Suburban (bose + xm + onstar +
indash 6 cd). But there is another place on Crutchfield's site saying it does.
I checked the manufacturer site which says it works fine, and I even called
Crutchfield to see if they could reconcile the difference, which they couldn't.
I ordered anyway, confident I could return it if Crutchfield's warning about the
cd changer was wrong.

I'm happy to report this unit works perfectly for me and all functions of my
factory radio are retained. The only thing you trade in this scenario is the
XM1 band is now used to select the ipod rather than used for XM presets. Since I
don't subscribe to XM radio, this is no loss. Then
within the XM1 band, I can move through the songs by song, playlist, artist or
album. This really is a plug-n-play unit and I'm very happy. It is as if it
came with the car from the factory.

The only thing I'm still trying to figure out is the best place to put the
little box. I've seen recommendations to put it above the xm receiver behind
the glovebox with the ipod in the glovebox. But I like keeping papers there and
it is a small glovebox. It will fit, but I think I can actually put it below
the cupholder in the lower console with velcro and then add an aux jack as well
to plug in something else.

All in all a very good purchase.

I purchased this item after much research. It was a snap to install and was
completed within a few minutes. Instruction manual is rather good though there
are a few misspellings. Everything worked as described initially but on occasion
the XM radio does not play as it should when the iPod is not connected. So far I
have not walked through the troubleshooting process with tech support. We'll see
how that goes. Overall, I am pleased and impressed and would do it again, even
knowing now about this one issue. Good product.

Crutchfield Customer Review (What's this?)

I've had this wired in to my 2003 Chevy Tahoe and it's been working great. The
staff at Crutchfield was awesome, and the order came with pictures on how to
install the cable. I had an installation question, called Crutchfield, and was
back at it about 5 minutes later. The tech rep was very helpful and knew what I
was asking.
The interface itself is easy to install, just 3 easy steps. Remove the factory
stereo, plug the interface into the existing radio plug, and replace the stereo.
The interface charges my Ipod as I use it, and saved me some money instead of
having to buy a new stereo with an auxiliary plug. Highly recommend!

Great Unit, Great Sound Quality

Written By Scott, Sacramento, CA on Saturday, October 30, 2010

To start, my application was different than in the other reviews. I have an '04 Tahoe
without XM (but I do have the factory Bose 6 disc in dash changer with the band button)
so it took about an hour to install. Installation was simple, i.e. you just plug in cables to
the factory harnesses. But I did have to take the main bezel off the dash and remove a
few other panels to route the cables so a warning to others: If you aren't
familiar/comfortable pulling the dash apart -Get a shop to install it.

Otherwise it works as advertised: The sound quality is great (good dynamic rage) and
my factory steering wheel controls work (program = playlist, seek = track). NOTE: On my
model car/stereo the radio does NOT display the song. I expected this (you have to have
the XM option for this), but I offer it as a heads up to others.

Fairly easy to install. I have a 2005 Tahoe and it took some fancy work to get the radio out enough to disconnect all the connections from the factory radio. After a few scratches and standing on my head i finally got it out and 5 minutes later I was done. Adapter works great. Doesn't work on iPads though. So don't get your hopes up like I did. Works perfect on iPod though.
