Hi,

Just came back from a 2 week holiday and now all of a sudden my PCM (911, 2005, 2s) pops up the error:

'error, cannot find navigation, amp, phone and CD'.

I have read quite some threads allready, but I am not sure where to start. I can pull the fuse and reinstall the software or should I check the MOST connections?

Where is my AMP located, also in the front or under a seat?

Regards, frank

Did some checkes this evening. Checked the most wire to the nav unit, CD changer, amp (thing located next to the emergency set) and also the PCM unit. All most cables are plugged in fine. Did notice a small tick sound when I touched the most cable going to the CD unit, but this is probable more a wish than reality).

I did not test the connection to the phone unit, because I have no clue where this unit is. I guess it is part of the PCM unit itself.

If I push main/trip than I see errors for NAV, AMP, CD and Phone. PCM and software are ok.

What to do next? Do I have to replace something, can I do other checkes? I also pulled fuse D9 to see whether this helped. Unfortunately not.

Could this be a software issue? I did cvhange the DVD a couple of months ago but it functioned fine. Did expecience some errors in the past year, but this was gone after turning the off and shutting the car for a couple of minutes. Errors were: no reaction to buttons and same error message as I experience now. This has happened 3 or 4 times. But this time it is more severe.

Regards, frank.

I presume you don't have a mobridge or dennison IPOD unit installed since you didn't mention it. My uninformed guess is that it might be a MOST connection. I say this because I have gotten the exact same messages on my 06 PCM2.1 and I believe it was related to a MOST connection. The PCM turned on but no sound and the error msg was displayed. After the first message, i tried re-seating the MOST optic cables that went to a dennison unit. that fixed it for a while and the messages disappeared. They reappeared several months later so I took the dennison unit out and all has been perfect ever since. Had to be the MOST connections. My error message was identical to yours.

Just a thought

Hi Bob, thanks for your reply.

Went by the dealer today and they diagnosed a faulty amp. Quoted me 1000$ for a 'new'one if I would return my old one.

I will take the amp out myself first to see if the is something I can see. Does anybody have the removal instructions?

To be honest, I would not be surprised if fixing the ampp is something that a local electronic specialist could easily do.

Regards, frank
