Question about 2002 Pontiac Bonneville
I am looking to upgrade the factory audio head unit in my 2002 Bonneville SLE. First I checked with Crutchfield and they stated that they have nothing that would fit. After questioning them they said it has more to do with the fact that the factory radio handles some of the warning chimes etc. I then went to a site called AutoToys and they said that I can replace the factory head unit with an after market and that they do have a wiring harness that will tie the OnStar (and assuming chimes etc.) into the radio. Is this a gamble I should take assuming that the interface does what it says or am I stuck with the mediocre factory stereo? Any advice is welcome.

SOURCE: installing after market stereo
You will need to go buy a wiring harness adapter from your local Walmart (usually cheapest there) or Local Electronics place (ie Best Buy). The wire harness that goes out from the radio goes into the Adapter and the adapter plugs into the car harnesses. Also these Adapters come with the wiring diagrams for your vehicle. They typically run 10 - 15 bucks depending on where you get them. Thanks for using FixYa!

you have to get the cable that conects your factory deck harness to the aftermarket deck, and that will allow you to use your factory speakers and amp, the wire harness is availiable at canadian tire or any stereo shop

Did the radio play after you took the key out?
And do the chimes come through the speakers?
If so, then you need to get a harness to go inbetween the radio and the car harness.

I have disabled factory xm/onstar units from many cars with no issue. i believe the onstar/xm units are both located in the trunk of you car behind the carpet (usually labeled accordingly). If you can find the fuse dedicated to the unit you can pull that. I have found the fuse is sometimes located on the unit. If you cant find the units then you can pull out the radio and unplug them from the back (more often than not it will be the smallest harness coming out the back). A quick way to test... have your car on and pull one plug at a time... make sure, once you have located it, test you audio (some harnesses are for amplified audio systems). The only neg. effect i have seen (rarely) has been the loss of the door chime.
