Hello,
Just purchased a 2005 Porsche Cayenne Turbo. The PCM was not working, so I bought a used unit. While everything (for the most part) works, except for the rear camera, amplifier, and stat radio (this one of no importance). I'd like to get the rear camera working as well as the amplifier, and don't care much for sat radio.

I replaced original PCM (PCM2.1E1 EC:103 Model: BE 6655) with a used PCM (PCM2.1E1 EC:103 Model: BE 6655) (Note: Same hardware)

Now to the issue: After pressing 'main' and 'trip' to display PCM info...

Amplifier, Sat Radio, and no backup camera... Error symbol for Amplifier and Sat radio. (Rear camera doesn't engage PCM screen)




Software (A or B?) Please explain...


The problem... How to fix?


The other problem... How to fix?


While I was told that I need to take into the dealership for programming, I'd love to save some money figuring this out myself, as I think it's quite doable. I'd simply like the Amplifier, and the rear camera to engage, and could careless about the sat radio.

I'd like to also at some point install an aux cable.

Thanks in advance.
