Overview

Our take on the Precision Interface Electronics GM9-AUX

Got a portable music player? Then you probably know that a direct connection to your vehicle's radio will give you the best possible sound quality. The Precision Interface Electronics GM9-AUX adapter lets you convert the CD changer port on your General Motors factory stereo into an auxiliary input, suitable for connecting an add-on satellite radio tuner, portable music player, or other audio source.

Got a portable music player? Then you probably know that a direct connection to your vehicle's radio will give you the best possible sound quality. The Precision Interface Electronics GM9-AUX adapter lets you convert the CD changer port on your General Motors factory stereo into an auxiliary input, suitable for connecting an add-on satellite radio tuner, portable music player, or other audio source.

Just plug the 9-pin data connector on the adapter cable into the factory radio's changer port, connect your portable player to the adapter's RCA inputs, press "CD" on the radio, and go! This adapter uses the CD changer port — once connected, you can't use a changer with your factory radio. Warranty: 90 days.

I used this interface in my 2000 Camaro with Monsoon single cd stereo to plug in my IRiver H10 mp3 player. It was extremely easy to install and it works just as advertised. The only reason I gave it 4 stars instead of 5 was how much it cost for how simple it is.

Tried others - this is the best!

Randy from Winston-Salem, NC on 8/10/2005

If this device fits your vehicle, buy it! I've tried TuneCast and cassette adapters - both stink up the place compared to this device. A little pricey but I'm convinced there's nothing better. 30 - 40 minutes to install, no tools required for an 02 Suburban and it works PERFECTLY. Anything with a miniplug jack can now play through my factory sound system. iPod sounds GREAT and I can't wait to hear my talking GPS over the stereo on my next road trip!

Perfect for Satellite Radio

Crutchfield Customer Review (What's this?)

This is a must have if you need an auxilary input for your factory radio. I used it to change the input of my skyfi2 xm radio on my 2001 Tahoe in order to eliminate the necessity of going through the FM on my factory radio. The XM programming is great, but the FM reception is awful, even with the wired antenna. If you are going to install satellite radio, buy this product. It installs in about 10 minutes , and you eliminate the static that you get from FM.The sound difference is amazing with this product. The XM will play through the CD/aux on the radio. You also never have to change the FM frequency from town to town to get the best reception.

Great Product!

Kent from Marietta, GA on 5/25/2005

This product is so simple to install (30 mins) and the quality of sound is impeccable. I installed mine in 2002 Chevy Tahoe and I have an IPOD mini. I also purchased the MONSTOR "Y" adater for use with my IPOD.<BR><BR>I was using a MONSTOR cassette interface before with good results, however the p.i.e. "aux in" product is incrementally better. The sonic difference is very noticeable especially in the bass notes.<BR><BR>

2002 Suburban Video Aux

Shannon from Atlanta, GA on 5/18/2005

Outstanding sound. I know this is advertised for IPOD or MP3 players, but I decided to try it for my Video system. I had an overhead DVD installed and the installer used an RF modulator. The sound was terrible, sporadic, and had the dreaded hiss. When the installers added the filters, it cause a sound loss in some speakers and didn't get rid of the hiss. You might think it was a bad ground loop, but I watched them try 3 different filters made by 3 different manufacturers. They also tried 3 different RF mods as well to no avail. I gave up and decided to try Crutchfield. Found this product, ordered it, rcvd it 2 days later, and spent 15 minutes installing in the port on my head unit that was used for my tape player (separate from the head unit). Wasn't sure it would work since it notes CD changer, but apparently the external tape port is the same 9 pin as the CD changer (assuming interchangeable)! Due to the extra wiring it's a bit cramped in getting the head unit back into the provided space, but it was well worth the price. I would recommend this to anyone with a video system. Forget saving a few bucks on a RF modulator and get great sound with less frustration.

Wonderful

Crutchfield Customer Review (What's this?)

I had my doubts, but after spending less than 30 minutes installing this baby my doubts were vanquished! It works much better than I expected - no hiss, no static, no interference from the local radio stations. The other reviewer was right on the money about the FM modulator, this fixed that issue and was so easy to install that I'm kicking myself for not doing it long ago! If you're thinking about buying this product, you won't be disappointed.

Great Product!!!

james from Ladera Ranch, Ca (South Orange County) on 3/18/2005

2002 Chevrolet Silverado 1500

I have a 02 silverado and the installation was really easy. It took me about 45 min. The Sound is GREAT! CD quality. Now I can enjoy my ipod in my car. I was using the Belkin TuneCast II Mobile FM Transmitter, what a waste of money!!!! Static or a hiss all the time. If your still using wireless your stupid. BUY THIS PRODUCT! And smash your FM Transmitter or sell it to some poor sucker on ebay.

Features

Overview: DPXTM Auxiliary input converters by PIE (Precision Interface Electronics) are designed to convert the CD Changer port of the OEM radio (with CD Changer controls) into an auxiliary input. Devices such as Satellite Radios, DVD Players, VCRs, MP3 Players, and Game Systems can be added the the OEM radio without an FM Modulator. DPXTM Technology maintains full function of all factory steering wheel and rear seat controls.

Compatibility: The GM9-AUX allows you to add an auxiliary input to the factory radio in select General Motors vehicles. The adapter plugs into the factory system using the supplied cable, avoiding wire splicing and modifications.

Note: In most cases the adapter takes the place of the CD changer or in-dash slave unit, so you cannot have a CD changer and the aux input adapter connected to your factory radio at the same time.

Mounting: The adapter can be secured to any flat surface.

Connections: The adapter has two RCA (left and right audio) inputs on one side. On the other side of the adapter is a rectangular 10-pin jack that interfaces with the supplied cable. The adapter end of the cable has the 10-pin plug and the other end has a 9-pin plug which plugs into the factory radio. If there is already a harness plugged into this 9-pin jack on the OEM radio (CD Changer/Data connector), the cable included with the GM9-AUX has a plug to accept this harness (this pass through connection allows full On-Star function but in most cases does not allow for CD Changer function).
