Have the Most system with CDR 23, radio stopped working. Now just flashes Porsche on and off on the screen. Is this the head unit or the amp going bad? Anyone have any experience with this? Thanks fellas.

 

head unit I think. you might contact Becker and ask them about it. Might have to send them the radio. Freezing up is common with these. all you do is turn off the key, and restart the car. usually does the trick. lots of info on this on Renntech.

 

I've had an issue where I hear a loud pop when from the radio after getting into the car. I turn the car off, click the lock button on and off then restart. Works after that. I haver the same cdr23 Bose system in a 2003 C4S.
