2003 CD Changer Schematic
Hi, I have a 2003 C5 with the factory CD changer in the rear. Looking for the electrical schematic for the rear wiring.
I want to identify the audio signal outputs, negative, and power leads so I can wire in my own 3.5m jack to connect my iphone and play music through the CD channel. I am not upgrading my stereo system until next year so for now I will do it this way. Yes I know they make adapters for this but they are charging $75 for them. I can do this myself fo less than $10. Thanks in advance!

This is AWESOME! Now to figure out the correct wiring sequence to tap into the CD aux port. The plan is to either tie into the CD changer or remove it and tap into the wiring for my iphone.
Thanks for the schematic!

I have read many threads on how to tap into the headunits, seen all the different commercial adapters and they all look like they retain the audio circuit of the head unit CD player or the CD changer itself. From what I have read it sounds like the system requires a CD playing for the CD channel to stay active.
Here is what I am thinking. Retain the working CD changer in the rear of the vehicle, with a few cd's left in it so the system see's it is activating. Now cut the sound signal wires , LT AUDIO BRN/WHT #367 and RT AUDIO DK GRN/WHT #368, then connect a 3.5m jack to those audio lines. At the CD changer tap the GROUND BLK/WHT #351 for the jack.
In theroy when you push the CD button on the head unit to change to the CD changer it will activate the CD's left in the changer and not shut that source down. This should allow any phone or other device to play the signal through the 3.5m jack and be sent trhough the LT AUDIO / RT AUDIO wires at the changer and sent through the head unit.
Time to get a jack and give this a whirl.

You can get a bluetooth adapter that plugs into your cigarette lighter and play tunes from your Iphone. That's what I use and it's not even close to 70 bucks......not a bad shirt term fix without cutting into the changers wiring.

My $17.00 lighter adapter works beautifully and sounds great. Much better than the OE radio. Lol
