Our take on the P.I.E Aux Input Adapter For GM

by Tim Sprinkle

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 GM12-AUXv2 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 connect the power and ground leads, plug the 12-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.

Note: Please enter your vehicle information then check the Installation Details to find out if this adapter is compatible with your vehicle. You can also call an Advisor at 1-888-955-6000 for help.

Our Product Research Team

At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere. That's because we have our own in-house Product Research team — they open the box, verify contents, check the owner's manual, and record dimensions, features and specs. We stay on top of new products and technologies to help people make informed choices.

Features

Overview: DPX 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. DPX Technology maintains full function of all factory steering wheel and rear seat controls.

Compatibility: The GM12-AUXv2 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. Please, use the Crutchfield Car Selector to determine if this adapter is compatible with your vehicle.

CD Changer/XM Radio: In nearly all cases the factory CD Changer, XM Radio, or rear seat entertainment system (when present) will work in combination with this auxiliary input adapter.

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 12-pin plug which connects to the factory radio. The included cable also has a third plug to accept the harness previously plugged into this 12-pin jack on the factory radio. In addition the OEM style harnesses, there are two individual wires that must be connected to constant 12 volts and ground respectively.

Aux input

Written By Henryb9, Newport News, VA on Tuesday, March 06, 2012
Crutchfield Customer Review (What's this?)
 
As I prepped by removing the dash, it wasn't hard to remove. After figuring out how I was going to run the cabling, next was connecting the power/gnd. After looking around, I noticed that you could use the hot-wire (from the wiring harness) from the radio, and I connected the GND to the back of the radio. Overall, not a bad install.
Pros:
Made my system in my truck sound as good as XM Radio, (Pandora, TuneIn Radio apps). I may be 43 years old, but it made me feel like a kid again by added audio equipment to a vehicle and turning it up because it sounded so good.
Cons:
As I was installing the GND on the back of the radio, I lost a screw that held the radio chassis together, so I used another one, but hung tight to that one, LOL.

Excellent Sound

Written By JustinP, Wales, ME on Saturday, February 18, 2012
Crutchfield Customer Review (What's this?)
 
This thing was a piece of cake to put in. I have a 2005 Chevy Trailblazer LT with the Bose system and the last thing i wanted to do was replace that beast with an aftermarket stereo, but unfortunately it didnt come with an AUX port. Thats when i found this... It fits perfectly and it works with XM (it actually uses the XM band function, but XM still works if you are not using your MP# player). In my case the only part that needed thinking was figuring exactly which wire to tap into, but in the TB's case it was the top orange wire on the harness, and for the ground i just found a bolt in the stereo enclosure itself and hooked it to that. I would highly recommend this to anyone. And as always Crutchfield gave me excellent service before i even purchased the product!!
Pros:
Great quality sound easy to install Crutchfield customer service
Cons:
None yet

Great way to get AUX into your car (2003 GMC Yukon)

Written By Zambini, Santa Cruz, CA on Monday, February 13, 2012
Crutchfield Customer Review (What's this?)
 
Don't forget the butt connector! (or some way to splice into your +12v line).

Installation was pretty simple, just took a bit to find the right way to power it. Works great and it was definitely better than replacing my entire head unit (cheaper, and I got to keep my head unit!).
Pros:
Inexpensive, easy to install
Cons:
Took a bit of research to find out how to power it.

2006 Pontiac Grand Prix

Written By Trashcat, Davenport, Iowa on Friday, February 03, 2012
Crutchfield Customer Review (What's this?)
 
Would have been great if it had worked. Reviews were insightful but none that pertained to me or my car. Crutchfield Staff was an excellent help, and their tech support was the only thing taht was keeping my from extracting the hair from my own head.

Would have been 5 stars if the product description would have informed me that in order for the adapter to work in my car, I need to have a car dealer (or a 3rd party car audio retailer) "activate my XM controller" in my OEM stereo. Unfortunately, the 5 dealerships that I was willing to drive to had absolutely no idea what I was talking about.

It just works - 2003 Chevrolet 2500HD w/Bose

Written By Marc, Dallas, Tx on Sunday, January 22, 2012
Crutchfield Customer Review (What's this?)
 
Installed in a 2003 Chevrolet 2500HD with Bose+Aux - works great! you have to toggle the seek button back and forth to switch between XM and Aux input and sometimes this takes a couple of trys. Works fine with iPhone and Samsung Galaxy S as source. Does not require you to disable internal CD player.
Pros:
easily adds Aux/iPod input to factory Bose system.
Cons:
none so far - hope it lasts

Junk

Written By DPM, AZ on Sunday, December 18, 2011
Crutchfield Customer Review (What's this?)
 
First one I bought quit working after about a 2 years. It produced nothing but garbled static and distortion out of just one speaker. I figured it lasted a good while, so I bought another one to replace it, and it only lasted 5 months before ending in the same fate. Should have known the quality was poor since they only warrantee the product for 90 days. Will not buy a third. Stay away from this product and just buy an aftermarket radio that's already got the iPod hookup integrated.
Pros:
Works great...until they break.
Cons:
They don't last. Poor quality product. Purchased two in the last two years and both are now dead. Will not buy a third.

GREAT Interface

Written By Dave, Cheyenne, WY on Thursday, December 08, 2011
Crutchfield Customer Review (What's this?)
 
'07 Pontiac Grand Prix GXP. Factory; Monsoon system, On-Star, XM , 6-disk in-dash CD player. Also have steering wheel controls, and steering wheel pattle shifters. Only thing missing factory litteraly was the NAV, and the garage door opener (LOL). Installation from start to finish took only 30 minutes. Left jumper in the 'XM position'. Removed a screw from the radio to ground to, 'T-tapped' in to the constant orange wire for radio for power. Ran the phono jack down and cut a small hole in the top-back-right side of the cubby to have cable come out. Seek up then down relatively quick and it's 'ON', do it again and its 'OFF'. Shows that I am still listening to XM though. You have to 'turn it 'OFF' though for XM to work again, even if you turn vehicle off. Everything still works as well. Even if you cycle through other parts of the stereo if the Aux was 'ON' it will be 'ON' when you go back to XM. GREAT GREAT GREAT Product!!!!!
Pros:
Quick, SIMPLE, cost efective sollution!!! So that I can retain my factory system!!!
Cons:
Having to wait for the shipping.

It Simply Just Works!

Written By vondoom88, nowheresville,IL on Wednesday, November 30, 2011
 
Install was on a 2008 Pontiac Grand Prix. I received this as a gift from my brother this year and the install was pretty easy. Hardest part was finding a 12v source and a good ground. Other than that straight forward plugs inline with the radios harness. add a 3.5mm to stereo rca cable and your all set.
Pros:
A simple solution to adding ipod/mp3 to your factory radio.
Cons:
Can't charge my ipod. Not a deal breaker for me.

This is a great product installed in 2005 Chevy Tahoe, Bose, in-dash 6CD changer, no XM. I was hooking up my Zune through the RSE DVD player, but now no wires hanging down and I can keep the factory radio look. I added a AUX-IN jack near the console to give my vehicle a finished appearance.
Pros:
Works as advertised. Able to keep factory radio and play Zune.

Amazing product!!

Written By DRMami72, Washington DC on Sunday, October 16, 2011
Crutchfield Customer Review (What's this?)
 
This product it's the best solution, do not use an FM transmitter if you have the option of using this instead. I'm a female and installed it myself, and that should tell you how simple it is to install. Sounds just as stereo CD quality. In my system sounds INSANELY clear since its on a 2004 Chevy Tahoe with Bose System....I wish I had known this product was around since 2005, could have saved hundreds I wasted with FM transmitters. Thank you for such great product and Crutchfield for carrying this reliable product. Your install instructions are flawless!!

'02 Pontiac Sunfire w/ Factory Monsoon System

Written By Daniel C, Raleigh, NC on Thursday, September 22, 2011
Crutchfield Customer Review (What's this?)
 
I bought this product from Crutchfield so I could play my ipod through the factory stereo system, but all did not go as planned. The installation was extremely easy, tapped into factory harness for power and ground, plugged everything in and....nothing. Quadruple checked power and ground, moved the internal "short" peg to every different position per PIE instruction sheet and still nothing . Finally gave in and called tech support to find out that early to mid '02 Sunfires have a different radio that is not compatible with the PIE aux adapter. I just wanted to post this so that anyone with my same vehicle hopefully calls tech support to find out if they have the compatible radio or not before purchasing; when I was searching through the reviews I didn't see one '02 Sunfire that had posted. But, Crutchfield's friendly staff have been completely understanding and are doing an exchange for an aftermarket Kenwood receiver as I type. I can't speak for the products performance (although if Crutchfield puts their name behind it, you can rest assure its good quality), but Crutchfield's awesome staff get five stars from me!

I bought this for my 05 Grand Prix with the monsoon stereo. Shipping was fast and installation was easy. The hardest part was getting power for the unit. I ended up stripping part of the power wire for the headunit and just using that. Still works great after 2 weeks.

2006 Pontiac Grand Prix

Written By redhead, Tucson, AZ on Monday, September 05, 2011
Crutchfield Customer Review (What's this?)
 
Couldn't be easier to install, removed radio, tapped into large orange wire for power and used a screw on the back of the radio for the ground. The cable was long enough that I was able to mount the box with Velcro to the back of the On Star box near the floor at the bottom of the console. That way if my cable ever goes bad, I can literally reach down under the dash at the front of the center console and unplug/plug in a new cable. It works perfect. I just push the band button to cycle thru the fm/am and then to the Aux input. I have the single disc cd player non-monsoon system.

P.I.E Aux Input Adapter For GM

Written By SMaz, Boston, MA on Friday, August 26, 2011
Crutchfield Customer Review (What's this?)
 
Worked exactly as advertised. Took less than a half hour to install. That's mostly due to easy access to the radio. Was able to wire in the power and ground right to the harness going to the radio with no problems.

Put it into a 2005 Pontiac Grand Prix GT with single disc factory radio. The CD/Aux button toggles between the CD player and the unit seamlessly. Partnered the unit with the Monster Mini Stereo - Dual RCA cable and dropped it down through the accessory tray under the radio.

Sounds just as good as the CD player. Strongly recommend this product if you are looking to keep your factory stereo.

The first adapter kit that I received gave me trouble. I contacted Crutchfield who guided me through some trouble shooting. When that was inconclusive, they put me in contact with the manufacturer's technical support, and determined that it should be returned. I contacted Crutchfield to tell them and I had a replacement received the next day. That one worked. I returned the first one and all is fine. The adapter installed just as they said and it performs just as they said. Very pleased. - Len

Works Great in my 03 Suburban

Written By Scott G, North Salt Lake, Utah on Saturday, July 23, 2011
Crutchfield Customer Review (What's this?)
 
Works perfectly in my 2003 Suburban. Easy install. The only issues I had were with the Suburban. Removing the radio was slightly a hassle as the wiring to the back was hard to pull making me worry that I was going to break something, However I did finally get it out and hooked the PIE unit right up. I ran power from the extra cigarette lighter wires which were easily accessible after popping the lower compartment display out. Once I was powered up I selected the accessory on the band switch plugged it into my Iphone and began listening to music immediately. happy with the result. The only thing I might have done differently is pay the extra for two day shipping as it took 7 days get get here. Sometimes I dislike UPS tracking because it tracks through 3 destinations in 2 days then disapears off the radar screen for the next 4 or even 5 then suddenly shows up. I know this is not a crutchfield issue and I am happy with their service.

2002 Trailblazer owners - BEWARE!

Written By JimB, NJ on Thursday, July 14, 2011
Crutchfield Customer Review (What's this?)
 
I used the Outfit My Car option on the website to find a unit that would allow me to add a portable device to my stock Bose system (with the in-dash 6 CD changer). The system told me that this unit would work with my stereo system. It does not work. I then went to the PIE website and read a blog from someone who had a similar problem and attached a picture of their stereo. It was the same unit that was in my Trailblazer, and the adpater didn't work with it. So, if you do consider buying this, do yourself a favor and check out the PIE website, as well, before ordering.

I chose to install this product in my 2007 Grand Prix, because no other "hard- wired" products were available. I am impressed with the construction of the product, including the new harness and connectors. Everything fits like it was meant to - from the factory! It is easily concealed behind my dashboard and the sound quality is wonderful. No FM modulator could come close. The Crutchfield Team helped w/ the process and also does a wonderful job of packing and shipping with INSTRUCTIONS specifically for your car - which is awesome. Def an all-around success!!

The Crutchfield website said it would work with my 2007 Chevy Express van. It is not compatible. I didn't find out until I had the radio out. The product seemed nice, wish it would have worked...

Your radio needs to have an external device capability like XM or a CD changer for this to work with a 2007 Express.

Written By ChrisK, Next to Nowhere, SD on Saturday, May 21, 2011
Crutchfield Customer Review (What's this?)
 
My factory Delco/Dephi unit has 4 speakers, single CD, no tape, no XM or Sirius. Do yourself a favor and READ these REVIEWS! Very helpful! ESPECIALLY the guy who mentioned the the product now comes with a spade on the yellow power wire that you SIMPLY can slide in next to the Thick Orange power cable on your existing wiring and it WILL STAY put AND power your AUX adapter. Pulled a screw out of the back of factory Delco radio and hooked ground up to that screw. Drilled a hole in the back of my 3" x 3" 'cubby hole' storage space next to radio in dash and put in a rubber grommet, fed my 6 foot RCA to 1/8" adapter cable thru hole and VOILA! Did not have to change any jumpers, don't even know where those are for sure?? My Band button now cycles FM1, FM2, AM, 1/Aux 1, and 2. Sounds very good! No more alternator interference like with the FM transmitter. Highly recommend this product...

I ordered this for my wife's 2004 Trailblazer so we could listen to our iPhones on
road trips. The installation was a breeze. I spliced into the ground and power
wires on the factory harness using a butt connector. The head unit automatically
recognized the auxiliary input.

I wish the unit was a little cheaper but it's worth the money.

excellent aux input

Written By Jerry, Chicago, Illinois on Sunday, May 01, 2011
Crutchfield Customer Review (What's this?)
 
Wasn't sure about compatibility so I contacted Crutchfield to Make sure. 2005
Chevrolet Colorado Crew Cab Z71 4x4. Factory in-dash 6 cd changer, no xm
or onstar. Device delivered in 4 days via UPS. Easy to understand instructions
except it didn't tell me which wires on factory harness were constant power and
ground. Called Crutchfield tech support and verified orange-constant power,
black w/ white stripe-ground. Pulled center off dash, used 7mm socket to
remove factory radio. Installed in under 1 hour. I just wish Crutchfield sold a
dash mount aux input. Bought a dash mount female input plug from another
vender for a factory look. Sounds exactly as if I am playing a cd. RDS
displays "aux in" while using my iphone4's ipod. Easier solution than replacing
the nice factory radio. Would recommend to anyone looking to outfit any car
with their own source of music without the crappy static from fm transmitters.
Thank you Crutchfield!

connector and tapped in to the orange wire from the factory wires. Reinstalled the
radio and hit the band button and hooked up my iPhone and it worked like a
charm. Great way to have an aux hook up. Great product and super fast shipping
from crutchfield once again.

Crutchfield Customer Review (What's this?)
 
Everything was fine testing this in my 2004 Traiblazer until I shorted out 2
wires and popped a fuse. Replaced fuse and it wouldn't work, spent way to much
time troubleshooting it to find out that inside the p.i.e. harness 2 grounds
broke that were connected only by a few strands of wire to begin with o_O. If it
wasn't for that this is a great product. My radio I just hit the band button
until it goes to aux1/2.

Installation was easy and works like a charm. Just make sure you have the right
jumper settings for the stereo you are connecting it to. After putting
everything back together I realized I forgot to change the jumper from XM to aux
(XM is the default). Other than that everything went smooth.

Great Accessory!

Crutchfield Customer Review (What's this?)
 
This worked fantastically with my 2004 Silverado 2500HD with factory Bose
system. Easy to install. To tap into a constant 12V source, I used an "Add-A-
Circuit" that I picked up from my local auto parts house in my fuse block .
Shipping from Crutchfield was speedy, and my order was packaged very well.
The sound from my Zune is much better now, compared to the cheap FM
modulator that I was using. I will definitely use Crutchfield again!

PIE GM12-AUXv2

Written By Fred P, Washington, MI on Monday, March 07, 2011
Crutchfield Customer Review (What's this?)
 
This item was EXACTLY what was described on the website and shipped ahead of
schedule. After reading through all of the reviews, I installed this in my 2004 Chevy
Silverado in 45 minutes. I have the Band/Aux button on my radio, no factory XM, no multi
CD changer. It worked great for me right out of the box. There is a ton of good
information in the reviews, do yourself a favor and read them.
Must have info:
Get a couple of wire splice connectors for the power and ground wires, I used the fat
orange wire for the power and the black with white stripe for the ground (check with a
meter to verify yours)
Get a piece of two-sided tape to hold the unit in place under the dash
You are also going to need a stereo mini-to-RCA adapter cable, spend the extra few
dollars and buy the Monster brand cable (Crutcfield $20). You dont want to have to take
everything apart in a few months when the cheap cable fails
Tape the adapter cable to the unit to prevent the RCA plugs from pulling out of the jacks
after you put the dash back together
Test the unit out before putting the dashboard back together, you may need to
change the jumper to match your radio. Also test the heater and A/C controls, you may
have knocked a wire loose while removing the radio
Turn the volume on your portable device all the way up. After doing this, the sound level
of the radio matched the sound level of my i-pod
If you have a problem, call Crutchfield, these guys are awesome!

2006 Tahoe

Written By Anonymous, Oceanside, CA on Sunday, March 06, 2011
Crutchfield Customer Review (What's this?)
 
Just isnstalled this device so I could plug my droid X into the stereo system to listen to
Pandora. Before that I was using the rear seat entertainment with the cables dangling
from the the dvd player. Anyway, the instructions provided were excellent. I had read
several blogs prior to buying so I already had quite a bit of info. Some concerns from
other buyers were they had trouble finding a ground. I actually just attached the ground
wire to one of the screws on the back of the actual stero housing which worked great.
The stearo has a built in ground attaching to the wireing harness. Also I already knew
the
largest orange wire in the harness was the hot/power lead. I had thought that installing
this would disable my XM, however, it does not. It does use that port in the back, but has
its own pigtail plug so for some crazy reason you did still want to pay for XM you can
still use it just fine. Still really don't understand why the system didn't already have an
MP3 jack from the begining! I certainly do not have any real knowledge or training other
than what I have taught myself and learned over the years. If you are wondering about it,
it really wasn't hard at all. Stuffing everything back in was a bit challenging. Also I ran my
leads behind and down and then through the bottom of the center consol.

Be Wary of Compatibility!

Written By A.J., Plymouth Meeting, PA on Thursday, February 24, 2011
Crutchfield Customer Review (What's this?)
 
Please be careful when buying this product! It is not compatible with my 2002 Pontiac Grand Am with the Monsoon sound system. When installed, the radio will not switch to AUX. I tried both the "XM" setting on the unit and the "Changer" setting. Neither worked. The adapter just went completely unnoticed by my radio. I tried two different head units, and two different GM12-AUXV2 units (Crutchfield determined that my first one must have been defective, and sent me another one). I tested my connections (which were soldered) with a multimeter. I'm a member of a forum for my specific car, and people there have said that, despite the 2002 and older Grand Am's having the 12 pin connector necessary, the radios don't have the internals to use them. Apparently, for the Grand Am, you need a radio that has "XM" printed on it somewhere. I'm told that 2003's and newer are capable. The manufacturer doesn't even seem to know that this product is not compatible with my car, so I certainly don't blame Crutchfield. They were very helpful with the troubleshooting, and I am completely satisfied with their customer support. It's unfortunate that this product just does not work with my car... now I'm waiting on my wired FM modulator.

2007 Envoy Denali

Written By WentPunk, Chicago, IL on Monday, February 14, 2011
 
Installed one of these in my 2007 Envoy Denali over the weekend. My stereo has
the XM radio, 6 CD built-in and onstar. It was NOT the navigation touchscreen
version. It does have the band button option. It took some time to pull the
radio but I followed the instructions included and it was dead on. You have to
remove a bunch of screws to move the center console back just a bit to get to
the screws holding instrument bezel in place and followed the rest of the
instructions. I tapped into the 12v adapter and used the truck chassis to attach
my ground and then put everything back into place. Overall, about 1 hour. I do
NOT have a XM license so I was not worried about that. I can hear XM if I don't
plug/play anything into the 1/8 jack.

The sound on this system is just amazing, just as good as a CD or anything else.
I did purchase a gold-platted RCA wire so I would have the best connection
possible.

I totally recommend this for anyone wanting an external adapter.

Nice piece

Written By W. Lindermann, Dover, PA on Monday, November 01, 2010
 
2004 GMC YUKON SLT
I took my advisor's recommendation and (Thanks Blake) bought, and installed the adapter.
As I had previously removed the dash cover and the radio a few times, it was a snap;
although this may be challenging for the first-timer. Installation was fast. Found a good
source of power right from the radio's plug in, and with a quick splice it was done. Now for
the ground................this was trickier. There is no metal, nearby to make a ground to! I
ended up undoing a small bolt on the chassis of the radio, itself, as it had to have it's own
ground.....somewhere! The bigger problem was to STUFF all that wiring and tuck the unit
away somewhere. This was finally accomplished by getting my hand behind the unit and
moving things until a good fit was made. Just a litlle cursing and about 45 min. and it was
done. Seems to work well, with good sound quality and little to no static. Output from my
MP3 is small so the volume on it had to be pretty well up.

What can I say, it works great in my 05 Monte Carlo with the factory CD player.
Hardest part of the install was getting the dash off, which was not too hard
because the Crutchfield directions were right on the money. I am using it with
my XM Skydock and my iPod. Much better than trying to find a empty FM station.

Best way to add an Aux audio input to your factory radio

Written By Christopher, Birmingham, AL on Monday, October 04, 2010
Crutchfield Customer Review (What's this?)
 
Easy to install once you have removed your radio. Simply plug in the wire harnesses, tap into a power source and ground and your ready to reinstall the radio. The only reason I didn't give this product a 5-star rating is because there's no indicator to let you know that the aux audio input source is active. Not a big deal but would be nice feature to have. Do NOT waste your money on a FM transmitter. Adding an aux audio input interface like this one is the ONLY way to go.

This unit IS compatible with Hummer H3.

Awesome product - follow others tips!

Written By Clint, Savannah, GA on Wednesday, September 15, 2010
Crutchfield Customer Review (What's this?)
 
I installed this in my 2003 Chevy Tahoe - Bose system with no XM, does have in-dash CD changer. The best tip I found was to use the wire taps. I picked some and it made all the difference. I also found a topic on another message board where a guy was installing it into his Avalanche and the pictures he posted assured me I was tapping into the right wires. I also wrapped plenty of electrical tape around the jumper cable's attachment to the unit to ensure it didn't pop out. Getting everything stuffed back in was the hardest part, but it finally fit and now I am rocking the iPod and XM radio in clear sound. The FM Transmitter is now just an in-car iPod charger. Awesome product!

Awesome, finally using my Zune thru my factory radio, sound awesome and works as advertised. The Crutchfield paper work was right on, as usual & this installation could not have been easier, a little over an hour, mostly because I didn't take my time dressing the new wiring in behind the radio. Used with the Soundgate Zune core package routed thru the glovebox , so I have the option to stor the cable and Zune out of sight. Would highly recommend. Now I can toss the zune car pack that never worked write.

very fast shipping and not to mention the free shipping was awesome. Pricy item just to

seek up once then down to switch from xm to phone. It is seek up 3 times then once
down, I would have not known that If I had not read the reviews. Took a little while for it to
work. It did it right the first time, but then didnt want to do it anymore. But it works fine
now, It just seems like it's tricking the system and bypassing something in there for the

Great instructions

Written By Wingnut, State College, PA on Sunday, August 22, 2010
Crutchfield Customer Review (What's this?)
 
This is my 2nd GM12-AUXV2. The 1st one died after about 1.5 years. The vehicle-
specific instructions that Crutchfield provides are fantastic. They are vital for figuring out
where to pry on the trim pieces; you can break things if you don't know what you're
doing. I had no problems installing either the 1st or 2nd adapter. We have (2) vehicles
with this adapter; on one, it's been working for 3+ years; on the other, it died after 1.5
years (out of warranty, naturally). Once installed, it worked great. It's so much better
than the default FM transmitter way of getting XM into the factory radio; in our area, the FM
spectrum is really crowded, and it's difficult to find an unused station. The direct method
is definitely the way to go. I'd give this a 5 if the 1st one hadn't died.

Sounds great

Written By Andy, Emmaus, PA on Saturday, May 22, 2010
Crutchfield Customer Review (What's this?)
 
I have a 2007 Trailblazer and the only think missing which always drove me crazy was an aux port. Finished installing this earlier today and the sound is great, compared to a wireless FM transmitter it's like night and day. Thankfully, the days of constant searching for a clear FM station and static filled music are over! I had an issue getting the power to work with mine the first time around, but solved my problem on the second try. Besides the normal struggle getting the dashboard apart after I found all the hidden screws, the installation was pretty easy.

The reviews here helped a LOT, if it wasn't for so many people sharing their information I would have thought my adapter was broke. Like others have mentioned in their review, I have to press seek up 3 times in a row, and then down once to get it to switch to my iPod, not once up and once down like the instructions state. There is nothing on my display that states the new aux port is active either, it just shows up as XM. If the instructions had been clearer and included this kind of information, they would have been much more helpful. All in all though, looks and sounds like a great product.

Precision Interface Electronics GM12-AUXv2

Written By rick, Milwaukee, WI on Friday, April 30, 2010
Crutchfield Customer Review (What's this?)
 
The installation of the unit took ~20 minutes. I had to call Crutchfield support to find a good place to ground the unit and I was told that I could use one of the screws on the back of the radio. The person who owned the car before me must have tapped into the power (fatter orange cable, not the skinny orange cable) on the radio harness (2006 Grand Prix w/6 disc changer. I reused this tap location and everything worked flawlessly thereafter. Make sure the jumper is in the correct position inside the box (XM or changer). All in all, the sound quality is ALMOST as good as a CD but beats wireless FM transmitters hands down. Now, I can play any song I want off of my mp3 player instead of having to rely on CD's. Very good product for the money. By the way, a big brand store (will remain nameless) wanted to install an FM modulator for $180. Buy this unit and install it yourself.

P.I.E Aux Input Adapter For GM

Written By Karl, Germantown, MD on Wednesday, March 31, 2010
Crutchfield Customer Review (What's this?)
 
Generally a very easy install on my 2007 Silverado Classic HD. The only problem I had was finding the correct hot wire to splice into for power from the radio's wiring harness. I assumed I should connect yellow to yellow. Wrong! I called Crutchfield and the tech was able to tell me that it is one of the orange wires. There are two orange wires, so I used my voltmeter to identify the hot one (the other is the computer) and re-did the connections. As another reviewer noted, the instructions on which jumper setting to use are not quite correct, so test it before you put the dash back together. And you do have to have the device output volume all the way up.

Crutchfield Customer Review (What's this?)
 
I received my adapter yesterday and installed it as soon as I was able. It went
in without a hitch, took maybe 45 minutest total and that was because I spent
time routing the cable for my zune. I had been using an FM transmitter adapter
that while it was okay, it did leave a bit to be desired. I was amazed at the
sound quality out of this adapter and couldn't believe how clear and crisp the
sound came through on my stereo. My zune has a spinning hard drive that caused
noise over the FM transmitter, but is quiet through this adapter. It's like
having XM back in my truck only I decide what music gets played.

Good Product. Works as I had hopped. Now don't have to use the FM signal from my iPod adaptor or from the XM unit I have in the truck. Just plug in the 3.5mm phone jack I routed out of the console. Kind of crowded behind the radio to make this fit.
One drawback, if I turn the truck on and the radio was already on and in one of the Aux settings, there is no display on the radio as if the radio is off. Little annoying, but I'll survive.

My Vehicle: 2004 GMC Canyon. My Radio: Stock w/single CD. Has a Band/Cd/Aux toggle button in the lower left corner. Easy install. Used orange wire in main radio harness for power, and used a nut on knee bar dash brace for ground. Did not move jumper, it was on CD Changer. Now the Band button goes through FM1, FM2, AM, Aux1 &Aux2. My Sirius radio plays on Aux1 and Aux2. Works way better than with the RF modulator.

2006 Chevy Trailblazer LT w/ Bose 6CD Changer

Written By Anonymous, Portland, MI on Monday, August 24, 2009
Crutchfield Customer Review (What's this?)
 
I was a little upset and surprised that crutchfield doesn't have vehicle specific instalation instructions for this unit, however once I had the dash apart it was fairly simple. I spliced into a 12v power outlet for my hot lead, and then got ground from a bolt in the dash. I did have to splice new ends on the adapter leads for 12V and ground. After that it was plug and play. I routed my RCA to headphone cord under the carpet and through the center console, so the wiring is completely out of sight.

Sound Quality is 200% better than with my old FM transmitter. It plays through the XM tuner on my stereo. I also like the fact that I still have the function on Factory XM radio as well as my CD Changer.

I didnt feel it was worth the price to get the adapter to be able to play my iPod using headunit controls, however for someone without mechanical aptitude, installation would be much easier with the high dollar unit, because they eliminate the need for splicing wires.

2005 Chevy Silverado 1500 Install Review

Written By Bryan, Wisconsin Rapids, WI on Sunday, August 02, 2009
Crutchfield Customer Review (What's this?)
 
I have a GM radio with CD and Tape deck in built in, BAND button but no CD changer or XM support. I also own an XPressRC XM radio and will be connecting that to the AUX input.

The info from Crutchfield was perfect for disassembling the dash. I removed the radio and HVAC controls so that I could have a little more room to work. I sourced power and ground from the cig lighters that are just above the center console, that panel pulls straight off. I used wire taps and ran extensions from those wires to the GM12-AUXv2.

My dash configuration has a large vent to the right of the radio and a storage area about 3" x 3" below it. I went to a local store and picked up a 1/8" female phono plug mount. I took a 1/8" male phono to 2 RCA male cord and cut off the 1/8" male end and soldered the wires to the female mount. I had to run a ground wire from the female mount to a ground location. I then drilled a small hole in the back of the storage area (that pulls out as well) and mounted the female phono mount. I then plugged the RCA plugs into the GM12-AUXv2.

I shoved all cables and the GM12-AUXv2 into the vacant area under the 3x3 storage area and then reinstalled that. Snapped everything back together and it worked perfectly. I used the XM setting on the GM12-AUXv2. I switch to AUX 1 and 2 with the band button on the radio or the source button on the steering wheel.

The reviews for this product got me through my install so I mine helps someone else.

"Band" Button Not Necessary (2000 Pontiac Montana)

Written By Robert, Castro Valley, CA. on Tuesday, July 07, 2009
Crutchfield Customer Review (What's this?)
 
Excellent product! Works as advertised, hooks up very easy, all factory
connectors. This will work with a radio that doesn't have a Band button, you
can toggle between the CD, and the CD Changer (which is now the unit), with
the CD/AUX button. You do have to open the unit and move the jumper to the
"changer" socket, as described in the instructions. I don't have a changer in this
van, but the plug is there to attach your existing CD changer if you have one.
The instructions tell you how to toggle between the changer and the unit, and
they haven't led me wrong, so I would presume they are correct. I think if your
radio has the 12-pin socket next to the main harness plug, this unit will work.

The input volume is a little lower, I have used an iPod and a sat. radio, both
with output volume all the way up, and the CD and radio come in a bit louder
when you switch back, but a minor inconvenience. It's not going to blow you
out of the seat.

I installed this in a 2000 Pontiac Montana minivan, and although the dash is
plastic, you can attach the ground wire to the mounting screw, as the radio
chassis is grounded by the harness. I soldered into the power outlet to get the
hot wire, though I needed a longer wire to reach. I don't like splicing into a
factory harness.

Gets the Job Done

Written By Robert, Houston, TX on Tuesday, April 28, 2009
Crutchfield Customer Review (What's this?)
 
It works great, the sound is much better than a FM modulator. I use it to get the sound from my phone and MP3 Player. I have the BOSE 6 disc in dash CD changer with OnStar and XM radio in a 2006 GMC Sierra. The radio sounds good to me, but was missing a aux input. Highly recommended if you are planning to keep your car or truck stock. The only thing i dont like is that in order to access the aux input, you have to switch the radio to XM, then press the SEEK UP button, then the SEEK down button. To switch back to XM radio, you repeat. It would have been nice just to be able to press the CD/AUX button on my unit. I tried to switch the jumper to changer mode to see if i could but would only work in xm mode.

With that said, it was worth the price to me. In order to have a aftermarket radio and for everything to work right, i would have to spend about 150.00 in adapters and thats not including the radio.

Just installed mine, took about 3 hours, but that includes running to the auto store for wire splices (get 2 of these, much better than cutting and taping).

2005 Yukon - Bose and XM. Crutchfields instructions on getting the radio out were right on. Very easy. Follow the directions to hook up the unit, also very easy. My vehicle, like most GM's has the hot wire as large orange and ground black with white stripe - this is on the other plug opposite the one the unit patches into. Wire splices very handy as there is not much slack and cutting, twisting and taping would be a pain. What is not perfectly clear to me is that the unit uses your XM bands as the Aux input. You cycle between XM or the new Aux by hitting seek up and down in quick sequence. When in Aux the display still says the XM band and channel you just left, the display does not change, but you Aux input music comes out.

So now the fun begins, getting all those wires and that box back in behind the head unit.....it can be done, be patient. It helps if you have a pet squid to assist you......

The good news is the wire and plug for you device (you did order the RCA adapter wires??) can come out anywhere behind the dash trim, which makes positioning it very handy.

Last hint, securely tape the splices and the RCA jacks. The last thing you want is to get the head unit back in after 30 minutes of cussin, only to find you pulled a jack loose in the process.

2005 Chevy Tahoe

Crutchfield Customer Review (What's this?)
 
I purchased this product after researching the item and reading the reviews posted on Crutchfield.com. The instructions provided by Crutchfield were right on with the removal of the trim panel and factory radio. When it came to installation tapping into the 12 volt constant (large orange wire) went without any trouble. I had a bit of trouble when I tapped into the ground wire (black with a white stripe). As it turned out I had a faulty ground connection. With the aid of a test light I was able to locate the issue and correct it. In previous posts that I had read the location of the jumper varied. For my application the position of the jumper was in the XM position even though my vehicle does not have XM radio or a CD changer. I found that there was adequate space behind the radio to place the wiring harness and auxiliary adapter. Over all my impression of the product is great, the sound is very clear, and volume is good. The product does exactly what I bought it for, to play my iPod. Good Purchase.

Once I realized that I had to hit the band button 3 times to get the sound through the truck's speakers it worked great. I listen to my Iphone via the truck speakers every time I am in it. I also works as a speakerphone for my cell. Thanks for the great product.

2003 Silverado

Written By randula, Harrisonville, MO on Monday, February 02, 2009
 
My girlfriend got me a Precision Interface Electronics GM12-AUXv2 so I could play my MP3 through my factory stereo in my truck.

With the installation instructions from Crutchfield, I had my radio out and the module plugged in in only a few minutes. My problem was trying to find a live power source for the 12 volt power. I gave Crutchfield customer service a quick call, they provided a wire description for me to tap into and I was on my way.

I had read the reviews on here prior to starting, so I was prepared with wire taps. I ran the module and the cable out behind my glove box. I've used the module to play both my MP3 and my XM Helix through my factory radio and I've been happy with the results. For the XM, the volume seems to be only slightly louder than the FM transmitter that I had used previously, but the MP3 works great through the module. So far, I'm very happy with the product and I hope I don't have the durability issues others have had.

Good sound, moderately difficult reinstallation of head unit

Written By Duncan, Franklin, TN on Sunday, January 11, 2009
Crutchfield Customer Review (What's this?)
 
I installed the PIE GM-12-AUXv2 in my wife's 2002 Chevy Venture minivan with OnStar, no CD changer, no XM. Her iPod sounds is very good and is near CD quality with no hiss or interference. I used wire taps to connect to the stereo wiring harness (larger orange wire is 12V+ and black w/white stripe is ground). I had to put the jumper on the center set of pins, and use the CD/TAPE button instead of the BAND button. There was room below the head unit behind the heater/air conditioning controls to mount the unit.

It took a while to get the wires routed due to limited space behind the head unit...I ended up removing the heater/air conditioning control panel so I could get my hand in to position the cables in while I reinstalled the head unit. I routed the RCA cable to the storage box below the dash, so it can be hidden.

4 stars due to short power/ground wires, a bulky, inflexible wiring harness, and a lack of included RCA adapter cable or wire taps. Be sure to order the RCA adapter cable and wire taps. The short wires make it necessary to tap into the head unit wiring instead of a different source of power/ground. I would have prefered a long ground lead to go directly to the van's body.

Works in a 2008 Trailblazer

Written By Dale, Grand Prairie, Texas on Thursday, January 01, 2009
Crutchfield Customer Review (What's this?)
 
I have a 2008 Chevy Trailblazer with the Bose 6 disc in-dash CD changer and XM Satellite radio (no nav). I had the Precision Interface Electronics GM12-AUXv2 installed today for about 40 dollars. It works great. All of the features my radio came with still works and I have an AUX input to run my Sirius Sportster 4 or a scanner through now. I used a phono cable with a noise suppressor in-line to make sure no electric whine was introduced to the system. If you need to add an AUX IN to your system, this is definitely worth the money to do it.

It took the installer less than an hour to install it. He used a multi-tester and soldered the power and ground wires in for a good, solid and trouble-free connection.

Purchased and installed this unit in my 2001 TrailBlazer. Worked fine for 7

works well, but questionable quality

Written By Scott, Dallas, TX on Sunday, November 23, 2008
Crutchfield Customer Review (What's this?)
 
This is the second of this product that I have purchased. Not because I liked it so much I needed two, but because the first one died after just over a year of use. I thought my luck would have been just missing a one year warranty, but it turns out the thing only has a 90 day warranty (which somehow made the situation better in my mind).
I decided to replace it with another one because the installation the second time around only took about 30 seconds: unplug the broken unit from the wire harness and plug the new one in. Still, I can't help but think that I could have purchased a much nicer receiver than the factory unit for what I have spent on two of these boxes. And besides, how long will the second last ?

Installed this aux input adapter into my Silverado. Went in with little problems, other than small space behind stock radio which has been noted. If it could be a tad smaller it would be better. Other than that its an A+. Sound quality is great(cant tell difference between cd and aux in) and volume is not an issue(I have a Bose system so that may be the reason for the higher power). Excellent way to upgrade a stock radio to add any mp3 player. Highly recomended.

2003 Pontiac Montana

Written By Sean, Colorado Springs, CO on Saturday, November 01, 2008
Crutchfield Customer Review (What's this?)
 
Great product. Worked better than I had hoped once installed. The best thing you can do is read these reviews. The best tool you can have besides a screwdriver and 7mm hex is a volt meter.

The panel came off very easily and I had the factory radio on the floor in no time. The Orange (hot) and black w/ white stripe (ground) were the correct wires to use as expressed herein by others. For this vehicle, there is no body metal to connect the ground to. Wire taps are the best way to access both hot and ground and really should be included in the kit. My time delay here was not pressing firmly enough on the wire tap and wasting time wondering why the radio didn't see the aux device (in this case an ipod). A quick check of points with the volt meter showed no juice to the tapped wires.

Once everything was wired correctly, I proceeded to test the system with the cover off of the converter. The proper jumper location in this case was the unlabelled position - not discussed by the PIE documentation. I had to play a little bit with the seek up and down to get the right signal - but pleasantly surprised that once this was set, the factory radio recognized this input by pressing the CD/AUX button - no messing around with BAND.

Reassembly took some time because of the bulk of the wires. All told - research - demo - trip to the store for wire taps - installation - reassembly and clean up - 4 hours. Don't kid yourself.

Excellent value, great performance

Written By Keith, Maryland on Wednesday, October 29, 2008
Crutchfield Customer Review (What's this?)
 
Crutchfield and Precision Interface Electronics both provided excellent
customer service and technical information. It's nice to call a manufacturer
and talk to a techie without feeling like you're a 2nd class citizen.

All FM Modulators I tried fell way short of the intended mark. All I wanted
was a direct auxiliary input so I could play my 32GB iTouch, nothing more.
For $70, this was the right product at the right price, less than ½ the price
of most iPod Adapters.

I have a 2004 Silverado with Bose, Internal CD, Cassette player, no XM,
and no CD Changer. My radio simply has a "Band" button. There was no
12-pin cable attached to my radio since I don't have XM or a Changer. So I
simply plugged in the PIE Interface 12-pin adapter into the back of the
radio, and ran a short positive and negative line to tap into the cigarette
lighter adapter.

Crutchfield's installation directions for removing the bezel and radio were
right on the money. With tight quarters inside the dash, smaller hands
would have made running the wires easier, but eventually I got it. Ran the
external cable out under the dash, and under the center console so it
comes up between my driver seat the console.

I'm slow and meticulous, so it took me about 90 mins total. Sound quality is
excellent because I enhanced my mp3 files (iTunes files are not the best
quality). If you don't get good sound or volume, tweak the files on your
computer first.

Great product for the money!

I own a 2008 Trailblazer SS with no aux output. I purchased the product and the install was easy! Don't remove the dash pieces, just simply drop open the glovebox all the way, reach behind and unhook from the radio. Simply plug in the leads, ground the wire to the metal dash bracket, and find constant 12V. Watch for the inflatable restraint wires - don't splice into those! It is activated thru my XM channel, and turned on by the scan up or down button. Sound is a little less than perfect, but not that noticeable. I would much rather give up a small amount of sound quality than to constantly change radio channels on the other adapters. Must have for ipod fans!

Good Product

Crutchfield Customer Review (What's this?)
 
this is a great product to have if you dont want to give up your factory 6disc changer. i have a 2006 silverado and it works really well. the only problem i have with it is that it doesnt use the cd/aux button (the aux part of it) but you have to use the band button on xm1 or xm2, then hit seek up once then seek down once (sometimes have to do this a couple of times) then it switches to my ipod. install was pretty easy. even though i dont subscirbe to xm, xm still works. def. worth the money.

the volume is a little low compared to "cds" even with my ipod cranked all the way up. so i just have to remember to turn the vol back down on my head unit so it doesnt blast my ears when i turn the radio back on. used it on my trip to the outerbanks this weekend and had no problems other than the ipod battery dieing.
