    I have had only 1 problem with my 04 Cayenne S, the head unit (radio/CD player) lost all sound, still powered up. I have the single CD unit attached to the changer. The car spent 2 weeks at the Porsche dealer while they ordered 3 replacement radios and could not get any of them to work, for different reasons apparently. In the end, they got one of the original replacement radios to work after the regional Porsche Tech got information to them regarding programming the fiberoptics a certain way.....that is what I was told anyhow. Also, while in the shop, they put a 5cm scratch deep in the front quarter panel, which they fixed. Needless to say, it was somewhat frustrating and the radio has gone dead once on me since. I figure it is a new/complex car and there will some learning on the Porsche mechanic's part. Despite it all, I still love the Cayenne. Anyone with radio issues? AK

    Re: Radio

    I take it you have the radio/CD only; no PCM unit? I have the PCM and I had one experience of no audio and nothing I did could bring it back. I did stop the car and restart it and that did no good. Later that day it was back. I talked to a Porsche technician about this because others have reported the same problem. He said some of these problems were due to the security system. The PCM unit checks with the cars computer system to confirm their VIN numbers match. Sometimes this confirmation doesn't go well even when the numbers do match and the audio amplifier can shut down in those circumstances. He said that locking and unlocking the car is equivalent to rebooting the system and should correct the problem. He also said there was a software update to correct the problem. It hasn't recurred for me so I haven't been able to test this. There are plenty of others reporting the same problem so I think it either has been or soon will be addressed by Porsche.

    Re: Radio

    Correct...the PCM does not work in Alaska and thus I have the CD/Radio/6-disc Changer. My problems were VERY similar in initially I lost sound, then it would come back on after the car was off and restarted later that day. Turning the radio on/off and restarting the car immediately didn't work. The sound eventually died for good. The mechanic was really frustrated with the whole process and told me he had to eventually program in a specific code for the fiberoptics to work...and there is a different code for different units (PCM vs. CD player etc). The dealer gave me a gift certificate to a nice restaurant to make up for having to drive an Audi A6 for 2 weeks and watch my car get gutted looking for a connection problem....This pic was taken from my front door in my pajamas...seriously .
