Hello:
My 03 996 with Bose CDR-23 Radio (with optional six disc changer) is having issues. The radio seems to always turn on, but no sound or very low volume comes out. If I pull and reinsert the two fuses that relate to the radio (D-8 and D-9) the radio works perfectly.
I have heard this is fairly common, and the fix is usually a replacement of the amp and/or head unit and/or cd changer. Can anyone tell me which one is usually the culprit? Any advice is dearly appreciated. Thanks, Ross
i have a simliar problem sometime... i just does not work. It turns on and stuff, but no sound... The only cure i know for that is, i turn the car off for like a Minute, later all is fine... Wierd. Next time when i go to the dealer i will talk to them about this
my 99 C4S just spent a week at my dealer with a similar problem, The CD changer would work, but not the radio. They finally tracked it doen to a loose connection in the fibre optic system,
ask you dealer to contact Gene at stoddard porsche for details
I have a brand new CR23 I bought sometime back for my car....the only problem is that guy didn't tell me that it only works on the newer ones with the MOST system in it. If you want it, I'll be willing to let it go for $100....I paid $300 for it and the guy wouldn't take it back when I told him it wouldn't work. I was pissed....but he could care less and never responded after I tried to return it for a refund. Never installed, but not doing me any good sitting in the box in the closet.
I have a 2003 C-2 with the same Bose system, and it did the same thing. While under warranty, the dealer replaced the headunit and amp. Since then, it has been great.
If you still have your warranty, take it to your dealership.
Hopefully this may help someone.
I took the car to dealer, no faults found but that thought it was a fault in the amp if anything. So I purchased a used "newer" amplifier, part #996.645.333.05... the part in the car was a much older 996.645.333.02... plugged it all in and seems to work, but need to give it a few weeks to see if anything happens with the volume. On the surface however, it sounds much "cleaner". Per a TSB on renntech, it seems the .05 is the more recent and fixes a lot of issues (i believe a .07 is out too)
Will let you all know how it goes - given the rash of CDR-23 Bose problems. Thanks, Ross
