CDR Radio and Amplifier Help

Recommended Posts


Any help appreicated, have some time on my hands this week so some DIY is in hand:

1. Just took out the CDR 22 (CDR220) radio and unplugged the power supply. When I plug in power supply it goes straight to wait and dose not ask for code? Do I just wait for an hour and does the radio need to be left on for this?

2. On looking at the back of the radio, the yellow wire which is plugged into socket C1- postiion 1 = Line out rear left seems to have been cut? Any thoughts why this would be and do I need to rewire it?

2. I finally got hold of the 6 speaker amplifier from a 996 M490 amp. Anyone any wiring diagrams for this amplifier, I know from other posts the socket to the current amplifier needs to be rewired.

Your help is much appreciated if anyone can shed any light on the above questions.

Thanks Toolpants, am trying to change the current 4 speaker amp to the 6 channel amp and connect some rear speakers. Looks like I'll need a pin extractor and plug in the new pins as suggested. But I need the wiring diagram for the amp to see where to connect the front and rear speakers. Do you still have the wiring diagram:


"I looked at the amp wiring diagrams for a 2000 Boxster and a 996 and they look the same to me for the pins. I scanned them so send me a direct email as you cannot do attachments with PM. There are 20 pins on each amp but not all the pins are used and/or work."

Your help is much appreciated.
