Need Help Converting from PCM1 to CDR 220
(same thread as in the 996TT section)
Objective:
Change from PCM1 in a 2001 996 Turbo to a CDR220 (not a MOST system)
Current Problem:
No Audio playing from CDR 220 once hooked up. Audio Line out Plugs do not have the same harnesses from the PCM1 as the CDR220.
Full story:
Okay guys, I just picked up my first porsche and I've seen the ipad mini install posted a couple other places which is the direction I'm trying to go. My problem is my car came with the PCM1 and I'm trying to swap to a CDR220 but I'm running into some issues getting it working.
I've bought a CDR220 and have a radio code for it. However, it seems the PCM1 uses a different style connector to run the audio to the amplifier than the CDR220 does.
I've got the CDR220 hooked up, it powers on, radio code works, antenna scan locks on stations, but I'm not getting audio. That's because only 2 of the 3 plug harnesses in the back of the CDR220 match over from the PCM1.
I'm wondering if anyone knows of a converter so I can use the wiring harness from the PCM1 to run the CDR220.
I'm including a couple stock photos below of the radio harnesses.
CDR220
Socket A (power/ground/illumination/etc) - Transferred
Socket B DID NOT TRANSFER (this is the audio out where I am stuck)
Socket C1,C2,C3 (transfer fine, this is cd player, aux, etc) - Transferred
Antenna
PCM1:
Plug A: (power/ground/illumination/etc) - Transferred
Plug B: Nothing Was Connected to PCM In This Slot
Plug C / Socket C: Socket C1,C2,C3 (transfer fine, this is cd player, aux, etc) - Transferred
Antenna - Transferred
Did Not Transfer:
Plug I : Video signal etc
Plug II: Data, voice/mic/etc
The following info is from renntech.org post link here

Confirm your wiring on socket A is enabling the amp which appears to be fed from socket C1. If you have the M680 DSP then no audio will play unless the DSP is connected also. (search other threads)

Rep Power: 33 I'm going to start researching this dsp issue, haven't heard of it before so I guess I'll soon fine out what I'm in for.

B8 RDC is correct about the amp remote on power. It is C1 #6. See my other thoughts in the iPad thread.
