Find what fits your car

Listen to your iPod — including newer models, like the nano, classic, and iPhone — and access all of its playlists using the controls on your General Motors factory stereo. This iSGM73 kit from iSimple includes a PXDP iPod2Car iPod interface and all the cables needed to hook it up to select GM car stereos. Just connect the interface to the back of your factory stereo via the included GM-specific cable, then plug in your iPod and go.

This iPod2Car interface lets you control the music with your radio buttons — even steering wheel controls if you have them — including controls for track up/down, fast-forward, and reverse. If you prefer, you can use the iPod's Click Wheel instead of the radio buttons. You won't have to worry about sound quality in either case — the wired connection ensures the best possible performance from your music. The iPod interface will even charge your iPod while it's plugged in. Warranty: 1 year.

Note: If you haven't already, please enter your vehicle information or call an Advisor at 1-888-955-6000 to find out if the included adapter cables will work with your vehicle.

Crutchfield Customer Review (What's this?)

I wanted to add an iPod adapter to my GM van after doing the same to my Toyota and Mazda. This unit was the most expensive and least functional of the three. At least for my vehicle, no control whatsoever other than volume from the factory radio. The iSimple manual confirms this.

Pros: Crutchfield support

Cons: No functionality or control of iPod from factory radio.

Works great on Camaro SS 2002

Written By Rick, Mount Prospect, Il. on Monday, March 09, 2015

Crutchfield Customer Review (What's this?)

I purchased the iSimple iPod Kit for my 2002 Camaro after chatting with Tech Support. The product was delivered quickly. The installation to my surprise was simple and took about 1 hour. The result is fantastic. I can now use my iPod Nano in my Camaro with control on my Monsoon radio or using the iPod. The only issue was that I have a 7th Gen iPod Nano with the Lightning interface. I had to purchase a Apple Lightning to 30-Pin Adapter to make the connection between my iPod and the iSimple interface since the kit only supports the 30-pin connection. However, it all works great.

Pros: Simple and quick to install. Works as advertised.

Cons: None

Basic Functionality with Factory Stereo

Written By VEC, Fletcher, NC on Wednesday, June 04, 2014

Crutchfield Customer Review (What's this?)

2002 Camaro Z28 with Monsoon stereo. Wanted to keep factory stereo since it plays great, just wanted to add Ipod capability. Since the info states that you can retain your steering wheel controls I ordered this unit. Unfortunately, the only controls you retain for music selection is seek forward and backward. With the CD changer I could select disks, songs within discs, etc. I was hoping to use the disk selector as a playlist selector, but that doesn't work. I'm still glad to have Ipod playback on the factory stereo, but don't think you'll retain all your radio controls as on a CD changer. The only way to have more control is to start the Ipod manually on whatever playlist you want, select "shuffle songs" if that's what you want, then let it rip.

Pros: Ipod playback

Cons: very limited radio controls, really need to use Ipod controls.

iPod adapter for Factory Radio

Written By JPorter, Dallas, TX on Saturday, August 18, 2012

Crutchfield Customer Review (What's this?)

Ordered this adapter to hook my iPod to my factory radio. I had used an RF adapter previously, but that wouldn't work in the city due to the large number of radio stations that would overpower the adapter signal. I used a cassette adapter for a while but eventually it started adding distortion and noise to the signal, I guessing due to magnetizing the tape heads. This product was fairly simple to install (clear instructions included). Had all the needed wiring harnesses. This was supposedly going to disable my cassette player, but it still worked. The radio had an imput for a CD changer in addition to the built in single disk player in the head unit and that is the one taken by the adapter.

Sound quality is great,. I even get some limited info on the radio display (problem is radio, not adapter) and can control basic functions from the radio. The cord to plug in the iPod is plenty long to allow lots of flexibility of where you want to place and connect your iPod. I have a small compartment under the cassette player at the bottom of the center console that has a door that lets me close it. I can put my iPod in there and have additional length of cord to allow me to easily navigate on my iPod but still see the road.

Would be a nice bonus if the cord had a built-in mic that would allow you to connect your iPhone and use it to do hands-free calls. Who knows. Haven't tried it with my iPhone.

Pros: Easity install. Great Sound. Retain full functionality of the radio, cassette and CD. Charges iPod.

Cons: Can't think of any.

Works as advertised!

Crutchfield Customer Review (What's this?)

Installation is a snap once you realize that the instructions are not particularly specific. Its pretty simple to pop of the dash trim, three screws and the radio comes out. Snap in the adapter harness, selected the dip switches per the manual, hook up a ground and constant 12volt source that thats it. The ground and constant 12volt were easy to find on my vehicle, '04 Chevrolet Silverado, the cigarette lighter is right below the radio/climate controls so it was no big deal to tap in there. I extended the ground/constant wires about 1ft to make things easy. Working in the dash of the truck is a bit difficult but if you take your time its not bad.

Crutchfield Customer Review (What's this?)

The unit was easy to install and to operate. It works just like the overview says, with one exception. I purchased the "adapter cable" to charge my Ipod. The "adapter cable" is the exact same one that came in the box with the unit. It has the same part numbers and is identical, but cost me an extra $25.99. The cable that came with the unit charged my Ipod just fine, so don't waste your $$$. It took me about 30 minutes to install in my 2007 GMC Classic. On the manufactures web site and the install manual it says that you will not retain your XM or CD changer. both of mine work just fine, and the Ipod works off the CD/AUX button. There is no display on the factory radio, which I though there would be, but as I look over the web site and the install manual they neither one say that, so my bad. The steeringwheel controls do operate the Ipod as far as changing songs and volume. So far I like the product.

Pros: Installs easy and works like it says in the description

Cons: You don't need to waste your $ on the "adapter cable" for a cable that is included in the kit!

Written By Brian, Lake City, Florida on Sunday, September 12, 2010

Crutchfield Customer Review (What's this?)

Instructions are very detailed and easy to follow and the installing it in my 2004 Aztek factory stereo went smoothly. I have an iPhone 3GS and it did charge it. However there are two issues with it. First and this may not be the fault of PAC is the iPhone prompts that the dock is not compatible and you have to press "Dismiss" every time you plug in. Second and more of an issue was, at least on my Aztek OEM stereo, every time I started the car it would default to radio instead of the multi-disk CD changer which this adapter uses to get the iPhone audio into the stereo. This is really a major issue for me. I contacted support and there was no way to avoid this behavior. Before installing this one I un-installed an old RCA input adapter which used the AUX in and it works as expected. I'm returning this and ordering a replacement head unit for my car. Time to move on and upgrade my OEM stereo.

Crutchfield Customer Review (What's this?)

Product works well in a C5 Corvette. Not giving it 5 stars because there is some lag in controlling the iPod thru the factory deck and sometimes the commands from the factory deck are not recognized by the iPod. Product works best when the iPod is controlled manually and not by the factory deck. Overall the product works well and it charges the iPod, which is a plus.

Didn't work well for me

Written By bunywail, Indianapolis, IN on Wednesday, July 01, 2009

Crutchfield Customer Review (What's this?)

I purchased this adaptor about 1 year ago - it worked OK - but I noticed
some problems with the audio coming from my factory installed CD player -
lots of crackling and distortion.

The way this installs is to interrupt where the CD player plugs in. In other
words - the CD player now plugs into this ipod adaptor - and the ipod
adaptor plugs in where the CD plug was.

I decided to live with it because I was much more apt to be listening to
the ipod than a CD. This adaptor would allow you to advance between
ipod songs from the factory stereo - but when you did this - there was an
unpleasant scratching noise associated with pushing the "next" button.
Again - I chose to live with it.

Anyway - about 2 week ago - I was listening to the ipod in my car and it
started to make a horrible screaching noise. As it turned out - the ipod had
been damaged and would no longer play anything normally - whether
plugged into this audio adaptor or not. Had to send the ipod off to Apple
and pay around $150 for repair. I have no idea if the adaptor caused this
issue - but to be safe I removed it last night and now I'm back to square 1 -
with no more ipod in the car.

Generally, I would give this product a thumbs down.

No Problem

Have a 2003 Chevrolet Avalanche, it took me longer to get the dash apart and get the radio out than to plug the Peripheral iPod® adapter in. The instructions provided for disassembly of the dash were exact to my project. Made it very nice. I had to tie into a power source and instead of taping into the radio harness, I found it just as easy to access the wiring from the accessories power adapter and cigarette lighter for my source. Whole project start to finish less than 45 minutes. Works great and has better sound quality than the plug in fm adapters I tried previously. Glad I made this purchase.

Crutchfield Customer Review (What's this?)

Easy to install. Customer service rocks! The other reviews here claim you
lose your XM and CD changer but that was not the case with mine. As I flip
through my sources on the steering wheel, it was like a new source was
created between the CD source and FM1. I do not like the fact that the
head unit won't display the songs and for some reason when I seek
backwards for a prior song it pauses the Ipod (Classic) but everything else
works fine. I found a clip for the vent that holds the Ipod to solve the lack
of head unit display and I am puzzled on the pausing when you seek
backwards but overall I am very pleased with this product for the price. I
will agree that flipping the 6 switch does help the sound. Easy to splice in
the ground and 12v wires into the charger socket just below the heater
controls, jsut be prepared to add wire because the yellow and black wires
out of the peripheral are entirely too short.

Written By Kristen, Seattle, WA on Sunday, January 25, 2009

Crutchfield Customer Review (What's this?)

This is a fairly straight forward item to install Simply pull your factory radio,
connect this to your Xm/or CD changer port, and if you want it to charge
splice it into your constant 12v wire. Pretty easy.

Obviously if you are plugging it into the back of your stereo into one of the
ports, than you will NOT be able to use that port for anything else. That is
also pretty straight forward. My radio had an optional cd changer that was
not being used, so I was able to use that port and not lose any of my
functions at all. It charges. Its easy to hook up.

And an added note. Even though the DIP settings say to leave #6 off. I
recommend turning it on. It is sort of an "internal boost" for the sound. If
you turn it on the sound from the interface will be much louder. Some
people dont mind having to crank the radio up to hear, but I prefer to not
have to adjust the volume when i switch between cd/fm/ipod.

Goodluck! And its a good product.

iSimple iPod® Interface Kit for GM

Written By Harry, Saint Cloud, MN on Saturday, January 24, 2009

Crutchfield Customer Review (What's this?)

After much research this interface seemed like the one to buy. I was really looking forward to using this in my 2001 GMC Sierra. I got it and installed it to find that it worked perfectly. For a day. Now I cannot control my iPod from the factory head unit, and I am getting a high pitched hiss whenever I listen to the iPod. The problem is in the connection between the iPod and interface, but I can't tell which is the problem. Overall it works good as long as you don't mind controlling the music with your iPod. A cassette adapter is way cheaper and the sound quality is equal. Maybe this would work better with a different vehicle...
To sum up:
easy to install
doesn't do what it claims (could be vehicle specific)
For the money, you could have a decent down payment on a nice aftermarket head unit with iPod controls built in. If you can install this interface, you certainly could install a new head unit.

Not Good

Written By Mike, Omaha, NE on Sunday, January 04, 2009

Crutchfield Customer Review (What's this?)

I ordered this unit after speaking with someone in sales here at Crutchfield. I asked several questions wanting to make sure this would work with all my factory items, (dvd, XM and changer). I got it and installed it. It worked well and was easy to install. Problem was I lost completly my XM1 XM2 as well as my CD changer. Not worth it in my eyes. So I took it back out, put everything back factory and shipped this back in for a refund.

Unit works well if you don't care about your factory CD changer or factory XM

Crutchfield Customer Review (What's this?)

Couldn't decide between Periferal or USA Spec ipod interface as a Xmas gift for my son. He has a 2001 Camaro, with Monsoon sound system. Have no regrets for choosing Periferal! Delivery was super fast! Only issue was trying to find the dip switch settings on as instructions said. After finally finding the settings, my car wasn't listed.

Installation was a breeze. 1st gen ipod Touch and a regular ipod work gr at. Didn't have to download latest firmware for the touch, I guess we had the latest already. Sound is awesome. Controls on the radio work the ipod as advertised. Plenty of room behind radio in the Camaro to mount the unit and stuff excess wires. I used automotive double stick tape to mount the unit.

Completely satisfied with Periferal and Crutchfield! Thank you Crutchfield once again!

Great sound

Crutchfield Customer Review (What's this?)

I installed this in my wife's 2004 Trailblazer. The Crutchfield instructions for taking apart the vehicle are wonderful. Step by step with good illustrations made it go easy. It took a little while for the stereo to recognize the peripheral so I'd recommend waiting for a while before thinking something is wrong with it. After several times of turning the stereo on and off it finally just started working and has worked great ever since. The sound is just as good as the CD's and when you shut the ignition off, it autmotically shuts the iPod off. I'm very happy with the purchase.

Great item, but....

Written By Royce, Sugar Land, Texas on Sunday, October 19, 2008

Crutchfield Customer Review (What's this?)

This item works pretty well, and is an outstanding unit for what I needed. That being said, I took a star away because the display on the radio doesn't show anything, and it gives a funny little noise when starting the vehicle. My truck is a 2000 Suburban, so results may vary. The first issue with the display doesn't make any difference to me, as I bought one of the Pro Fit mounting brackets and used the belt clip on the back of my iPod touch case to mount it right where I can see it, use it, etc. All I really use the peripheral unit for is to get the music to the radio. I've already gotten used to the funny little noise on startup. I wish the unit would pause and play when I leave the iPod in my car, also, but that's a small issue. Great sound is really all I wanted, without having to change the factory system, and it's what I got. If you want a true, full function unit, and you have an older radio, you may be disappointed, but that's just my opinion. Cheers!

A little tricky to setup but works great after figuring out some discrepencies in the instructions. I emailed Crutchfield with questions and the answers cleared up most of the problems. The setup listed for my vehicle was wrong but after looking at part numbers and discriptions I was able to figure it out.

Not for iPhone 3G!

Written By Scott, San Francisco, CA on Wednesday, July 16, 2008

This product will not charge the iPhone 3G. Peripheral tech support has confirmed this and says they have no solution at this time. Music playback still works.

For my regular iPod video (5G) the product works acceptably well, but is flaky. Skipping tracks via the head unit sometimes works but often doesn't. Or sometimes an attempt to skip one track forward results in it skipping backward 5 or 10 tracks instead! Powering on and off the iPod is also not entirely reliable.

Unfortunately it is the best solution for many applications. You can keep the factory look.

Looks great, should be easy to install. Only problem - if you have a GM vehicle, you will lose your XM radio unless you find the XM box and install a toggle switch (to switch between XM and the iPod). I have a 2008 Trailblazer SS and to get to the XM box, the air blower is in the way. I returned the product and hopefully something that allows the XM to work without much trouble will come out in the futue.

Works decent

Written By Patrick, KCMO on Friday, June 20, 2008

Crutchfield Customer Review (What's this?)

After trying this unit and the USASpec (one right after the other), I decided to go with the Peripheral. Here are a couple things I found out through my ordeal.

- Crutchfield tech support is great. This has got to be one of the EASIEST companies to purchase from online. Never worry about having to make a return. Customer service matters to these folks.

- Both units sound great.

- The Peripheral unit gives you more control over the iPod than the USASpec one does (FF, RW), but neither display song title on the head unit if you want to have full control of the iPod

- The Peripheral version requires splicing (constant power and ground), but the harness takes up much less room than the USASpec. The hardest part truly is getting the head unit back in the dash. This one is much easier.

- If you have added an XM kit to your vehicle (XM Direct), be sure to remove the add on harness. Everything will connect with it in there, but the unit won't play.

- This unit has an 11' iPod cable vs about 3' with the USASpec

All in all, there are positives and negatives to both units. This one, for me at least was the least complicated overall.

Crutchfield Customer Review (What's this?)

Product is flawless!!! Very easy to install and hook up, it came with several types of adaptors so having the one you need is probable. It also charges the ipod when connected. You can create a special playlist for the ipod that is for traveling in car and set it up before you pull away. Then just plug it in and dirve. The stereo will allow you to skip, fast forward, rewind and set to random.

The web site you have to go to, to get the dip switch settings for the device is the only hick up. its a little difficult to navigate to exactly what you need but not impossible.

Highly recommend this product.

Peripheral iPod adapter for 2002 Z06 Corvette

Written By Steven, Cincinnati, OH on Friday, June 06, 2008

Crutchfield Customer Review (What's this?)

The adaptor kit came with a GM wiring harness that plugged into the factory radio and allowed one of the three included peripheral harnesses to connect to the peripheral box. Once the dip switches were set (had to go to the internet) for the the correct peripheral harness everything worked.

The included instructions were too generic to be of any use, so I had to call Cruthfield to get help (they were great), but once that was done everything was easy. My 2002 Z06 Corvette now has iPod tunes that sound great!!!

If you're looking to connect your iPod to your factory stereo, this is the way to go!

I purchased this item, half expecting it to work. Also, half expecting I would be able to easily and successfully install it... However, when it came time to install, I wasted more time opening the box and unwrapping the contents than I did installing. It literally just simply plugged into the rear of my factory radio in my 2000 Camaro SS. As soon as it was plugged in, it worked. Simple as that. ( I did have to refer to the item's web site for a code for the item, which was easy as well) Also, the sound quality is excellent, and I can now control my Ipod through the radio and steering wheel audio controls!!! I HIGHLY recommend this to other frustrated users of FM transmitters, and to those seeking CD quality sound!!!!!!!!!!! I LOVE CRUTCHFIELD!!!!

This is a great product. I purchased the other GM I-Pod unit. It had to many limitations. With this unit, you can use your I-Pod as if it weren't hooked up to your car.

This is the best product out there for GM factory radio's!

Caused Lots of Problems

Written By Mike, Macon, Georgia on Wednesday, November 28, 2007

I purchased this product in December 2006 and had it professionally installed in our 2003 Suburban (factory Bose system w/ Onstar). Shortly afterward I began using this, the battery died in not one, but two, of my IPOD Nanos. I was suspicious that this was overcharging my Nanos and burning up the batteries. To try and determine which gave me better service, I returned one Nano to Apple and has the battery replaced and sent the other off for service. I received both Nanos back and within a month neither would hold a charge again. Once again, this adapter was the prime suspect.

Works just well enough, but not as good as expected

Written By TobeZ, Massachusetts on Wednesday, April 11, 2007

Crutchfield Customer Review (What's this?)

If your expectations aren't too high, you'll be satisfied.
Pros: Install of Peripheral PDXP was *very quick* in my 1999 Cadillac Seville. Two screws to remove old CD changer, and one connector pull. Set 2 DIP switches on unit and tncluded harness plugged right in. *No splicing required for my car! Nice! (Note: Install instructions indicate that some other cars require splicing.) Audio level is correct and sound is much better than any modulator.
Cons: Control is less than perfect. "Next Track" works but "Prevous Track" usually doesn't. Pause/Play state can get confused. In both cases, I need to intervene on iPod.
Overall: Even though I was disappointed by the imperfect control integration, I'm not returning the device. Because the PDXP has an iPod dock connector, it charges the iPod, and because it replaces CD changer, it gives a direct line-in. These attributes alone make it worth buying and keeping.

Overview: The iSimple Interface allows you to control an iPod directly from your factory radio in select vehicles. The iSimple delivers CD quality sound directly into the factory system via the CD changer port and eliminates the use of RF modulators. The factory radio enables track selection and fast forward/rewind just like using a CD changer. In addition, the iSimple allows you to keep full control of the iPod from the click wheel. The iSimple also keeps the batteries in the iPod charged. If the OEM CD changer is present, you will have to disconnect it to install the iSimple adapter.

Vehicle Compatibility: The supplied harnesses are compatible with select GM vehicles, including Buick, Cadillac, Chevrolet, GMC, Hummer, Oldsmobile, Pontiac, and Saturn.

Note: Please use the Crutchfield Car Selector to verify compatibility with your vehicle.

Vehicle Specific Harnesses: Depending on your vehicle, you will need one of the following harnesses:

  • PXHGM1: One end of the harness connects to the iSimple Interface and one end connects to the factory system. On the interface end, the cable has a translucent rectangular 22-pin (6 pins present) female connector that plugs into the iSimple Interface. On the opposite end, the cable has an 12" jumper section that interfaces with the factory system. The jumper section has a black rectangular 9-pin female connector on one end and a white rectangular 9-pin male connector on the other end.
  • PXHGM2: One end of the harness connects to the iSimple Interface and one end connects to the factory system. On the interface end, the cable has a translucent rectangular 22-pin (7 pins present) female connector that plugs into the iSimple Interface. On the opposite end, the cable has a white rectangular 21-pin (7 pins present) male connector that interfaces with the factory system.
  • PXHGM3: One end of the harness connects to the iSimple Interface and one end connects to the factory system. On the interface end, the cable has a translucent rectangular 22-pin (6 pins present) female connector that plugs into the iSimple Interface, and 8" constant power and ground leads. On the opposite end, the cable has a 7" jumper section that interfaces with the factory system. The jumper section has a black rectangular 12-pin (10 pins present) female connector on one end and a gray rectangular 12-pin (10 pins present) male connector on the other end.

Note: Apple iPod/iPhone software updates may change functionality results. If you download a newer software version, you may need to reset the factory radio and your iPod/iPhone to regain functionality. If this doesn't work, you may need to wait until an newer software update is available.

Radio Display During iPod Operation: The iSimple Interface does not send any information from the iPod to the radio. This means that the disc and track numbers shown on the display will not reflect the song number on the iPod due to the complex nature of the music library.

Steering Wheel Controls: If your vehicle's steering wheel controls have the ability to select track and control the forward and rewind functions of your factory CD changer, then they will also control these same functions on the iPod.

Programming the iSimple: The interface has eight dip switches on the side. Different vehicles require different switch configurations. A chart on Peripheral's web site shows the correct harness and dip switch configuration for your vehicle.

Note: The dip switches must be set before the interface is plugged into the vehicle.

Installation Location: Most installations will require you to remove the factory radio in order to plug in the vehicle specific harness. Some vehicles may require you to connect the interface to a factory pre-run CD changer cable. The location of these CD changer cables will vary by vehicle. Some common locations of these cables are in the trunk, behind the glove box, and in or under a center console.
