A few weeks after getting my CD changer installed, I noticed a malfunction. While listening to CDs 2 - 6, if I press the button to select CD 1, nothing happens. If I then press the button for another CD, other than CD 1 or the one I'm listening to, it goes to that CD. Then I can select CD 1 and it works fine. Turn off the car and the same malfunction happens.

So I took it in to the dealer today. They swapped out the radio, same problem. Swapped out the CD changer, same problem. Went to a new car on the lot, same problem. Swapped out the radio in the car on the lot, same problem. They said they believe it's a problem with the radio (CDR-23) and reported it to Porsche and will let me know what Porsche says.

Anybody else have this problem with a CDR-23 in a '03 or '04 with the MOST bus?
