Radio
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
