Cdr23 To Pcm 1! Please Help With Buttons!

Recommended Posts


I own Porsche Cayenne 2006.

I just have replaced my Becker cdr radion with used PCM 1 module from 2004 Cayenne!

A donor car was a Bose car with phone, amp and CD changer.

My car is without Bose, phone, CD changer and Bose amp.

When I have installed that pcm module I have an error notice: "System error: amplifier, CD changer, Phone not available"

I hear the sound and CD works but all menu is freezed and none of the buttons are working, only volume control and I can switch it on not off. Outdoor temperature and clock indicators are working according to my tunings.

Now I cant take out my CD because my buttons dont react.

Please tell me is it possible to reprogramm and erase this error at dealers because I think that any module can work without amp, phone and Changer (I think my non Bose amp now working, it cant find bose original amp)

What can you tell me about it please? Maybe there are ways to fix it myself with my hands?

The main problem also I think is in these buttons! Please anyone knows how to get these buttons work? are these buttons independent from cars tuning? I cant even imagine the real reason of buttons failure!
