Broken PCM 2.0
I decided replace my Sim-card tray this weekend and now my PCM unit won't even start up.
I can hear a soft noise coming from the speakers and the disc is spinning but the screen doesn't come on unless I switch off the ignition. Then the Porsche logo appears for a while but goes blank again. I have opened it up several times to make sure the connectors are connected correctly and it all look to be ok. I have tried removing the fuses related to the PCM unit and disconnected the battery but the problem remain.
Anyone with any ideas?

I fixed it!!
Apparently you have to connect it in a correct order for it to work. Start with the big MOST plug, the power then the rest of the connections. I don't know how many times I have taken in down to pieces and back in again. Such a relief!
