Question: Will this fit a 2005 Pontiac Grand Prix. Geek Squad at Best B said I needed a special harness that cost $130.00.
Document: If you own a 2005 Grand Prix, DO NOT order this one. The connector is not the same. I had to buy one locally to install the radio and return it. For a $5 cable, it cost me 2 to ship back...disappointing.
This was perfect, and was exactly what I needed. A similar item at Best Buy cost $20.00. I soldered all of my connections which took a few minutes, but other than that, this made stereo installation "a snap". Good product!THE GOOD:  Cheap! And, exactly what I needed for my '98 full size Chevy truck.THE BAD:  Nothing bad about it.THE IFS:  Lots of wires to connect to, but there is no way of getting around that.
My local retailer had this exact same thing for $25.00. I paid $4.00 including s&h. Works extremely well too with my pioneer radio in my 99 grand prix.
This product does not fit a 2005 Chevrolet Silverado w/ OnStar and Bose Sound System. Instead the adapter for the OnStar and Bose Sound System is more than the price of the aftermarket radio I purchased. The correct adapter is about $130.00 at the lowest price I have found. Very Misleading on this product.
Although all the descriptions say it will fit/work (and I read through the choices carefully), it does not work. I needed the Metra GMRC-01 Axxess Non-Amplified/Non-OnStar Interface Harness for Select 2000-2005 GM Vehicles. Amazon, as always, was great in resolving.
Although Amazon said this was the right part for a 2004 Avalanche and the packaging says it is for a GM 1988 - 05 this is not the right part for me. What I needed was a Axxess GMOS-04. I found the part at a local auto audio shop for $129,  I am sure you could find it for less on line. So be sure you get the right wiring harness.
However, this was my first time working with car electronics of any kind, so I really didn't know what to expect going in. Having said that, even with that setback it still was not difficult to use and now that everything is straightened out it works great. No major complaints. Just be prepared to adjust some wires. A quick search on youtube for removing wires from a wiring harness was all I needed to correct the problem I faced.
Do not buy the wiring harness if you own a 2000 to 2005 Oldsmobile,Buick Le sabre Pontiac Bonneville it will not work you will need pac cr2-gm32r to install a new stereo [...] that's where ya get it at  good luck
Worked like a charm in my 98 grand Prix. Wire colors even matched my new Kenwood HU. Don't hesitate to buy if you own a grand Prix. It'll save you a lot of time/frustration.
Do your research! This is a &#34;universal&#34; port for car audio installation. It was the wrong part for my 05 Chevy Malibu Maxx even though multiple websites said this would work. Now I need to have the installation finished at best buy for more than $100. Very disappointed.
Answer: They are most likely correct. The harness is for the simple radio. Most newer GM vehicles have the door chime running through the stereo system. I purchased it for a 2005 Silverado and ended up having to get the more expensive style. Check with a local car stereo shop other than best buy. I got one for $89.99. Hope this helped.
