DSP no audio Nightmare, help please someone.

[Harkoon]

Hi

I have been trying for 8 months now to get my Audio system in my beast to work now.

Its a 2000 M5 with DSP ..

I have changed all the units in the trunk due to water damage . The only problem is its seems to be some kind of bad wiring left.

Here is the problem : If i jiggle all the wires in the trunk the sound will suddenly play and all is sweet , but if i jiggle some more hit a bump etc the sound dissapears, also the DSP feature on the Menu dissapears. This happens with CD and Radio..

I have tested the "Remote turn on signal lead" so the Amp is on.

Its likely to be some kind of communicating cable , but thats just assumtion ? Any ideas on Which wires it could possibly be?

All help will be very well recived..

Best regards
