2004 GXP CD Changer
Anyone know where I can find an OE CD Changer (trunk-mounted) for my 2004 GXP ?
Basically, I just want a cd changer for my car, but my main concern is being able to operate the unit through the factory radio/controls. I do not want to scar the look of the interior with a remote control taped to the dash!
Thanks!

The CD Changer is only the beginning. I believe you will need to add a wire harness and this includes adding connector pins in the Dock-N-Lock connector the OEM head unit plugs in to.
Thanks guys for replying so quickly.
I'm prepared to spend about $300 in parts (cd changed unit included) and $150 to have it installed for me.
I have very little technical experience, so installing it myself is pretty much out of the question
Also, I have OnStar and want to keep it, I do not have XM/Sirius

These are available for varying prices on eBay. As hawkjet says, you won't have the wiring. I previously built a harness for another member so he could add this option as well. Difficulty depends on whether you have a particular connector in place. Since yours is an '04, I'm optomistic. I'll post a picture later today of what you need to look for. If it'* there, this should not be a difficult project
Okay Soochie1:
The first step in creating an action plan is to determine if you have connector C217. This is a black 4 cavity connector that allows for the connection of an audio input to the head unit from the XM receiver and/or 12 disc changer.
C217 is located under the dash just to the right of the steering column. To view the area where this may be located, the knee bolster must be removed. This is the panel that runs across the lower part of the dash just in front of where the drivers legs would be.
To remove the knee bolster, grasp the top portion (just underneath the steering column) and the lower edge. Pull sharply straight backwards toward the rear of the car. Below is a picture of what you will see once it'* off:

To expose the area where you should see the connector (if your car is equipped), you need to lift up on the trim piece attached to the bottom of the steering column right where it meets the dash. This is what you should see:

Towards the right you should see a yellow connector clipped to the dash. This is an airbag connector. Somewhere between this connector and the steering column you will hopefully find C217.
In the picture below, you will see mine. In my case, both halves are there. IF your car is equipped with one, you will only see the MALE half. It should also be clipped to the dash. There will be four wires attached that are:
A. Bare (with a clear insulating sleeve)
B. Black with a white stripe
C. Dark green with a white stripe
D. Brown with a white stripe.
You can't see those colours in the picture below, but you can see the connector. Again, your car (if equipped) will should only have the MALE half.

This connector, as I understand, MAY only be present on the 2003-05 Bonneville. This post does NOT apply to the 2000-02 model year vehicles.

Heres what I found (these are the 2 clearest pics I took)


I could not find C217, or any wire that wasn't already connected to something.
This was really all I found:
the cluster of wires to the immediate left of the steering column, and to the far right the yellow airbag connector you mentioned. In between was a small black box with 3 or 4 small individual wires coming out the back and top. (this may be related to my remote-start or amp/sub (?).
I stuck my hand as far back as I could to try and find any other wires that I could gently pull into view and identify, but I could not find any. So I'm assuming that C217 is either not in my vehicle, in a different location, and just stuck behind one of those large obstructions.
any other help/guidance is much appreciated!

You make mention of an amp/sub in the last post. Is this something in addition to the OEM stereo?
You probably don't have C217 if it isn't in sight. It clips onto the instrument panel frame in fairly clear view. The only other way to absolutely confirm would be to pull out the radio and look at the connector there. This isn't too difficult if you're up to it.
It is still possible to add this. The harness I built for the last member didn't have this connector either. It just means the wiring must be run all the way up to the back of the sterero head unit and added to the connector there. The down side is that the terminals needed to add to that connector are expensive (compared with the other connector) because they are next to impossible to get. I do have a source for a limited number of them though. It'* also more work because it'* pretty tight in behind the radio.
There is one other connector needed. I ordered some a while back for another project but there is about 45 day lead time and I won't likely see them until mid May. There is another option to this as well, but again it means a little more technical skill and time to install.

Thanks again for the quick reply!
The amp/sub are aftermarket.
But as a sidenote, everytime I look at the CD/AUX button on the radio I wonder why there isnt more readily-available access given so we can actually use the AUX feature lol.
How much work is involved in getting out the radio to check for the connector there? I'm willing to pull it apart and take a peak, as long is there is minimal risk that i'll permanently damage the radio (as i'm sure it will take many paychecks to replace haha).
