So did you get it to work? Or did you have to replace some modules? I gote the same issues but worse symtomps my screen is totaly black but only a flodded dsp no water in battery tray.
Plese let us know how it whent.

Your problem is probably a fried nav computer and DSP amp. Since the two are near one another and you have water in the DSP, you likely have water in the nav computer. The nav computer is the device that runs the screen, so that explains the black screen.

Start by replacing the nav computer. After you get the screen back, check the radio and DSP functions. If radio works but no sound and no "DSP" option on the menu, then replace the DSP amp.

Hello Brain
I have a separate thread about my problems please take a look

http://www.xoutpost.com/bmw-sav-foru...tml#post907089

still havnt been able to locate a radio module, i live in vancouver BC

post #11 tells you where to look for the radio module, post #20 shows on the last picture the L shaped bracket where the radio module sits...

some good news,

have a appointment set up with my insurance company - they might just end of covering the radio module, and if my bluetooth/cd changer/gps/subwoofers/pdc module are damaged by water then they will b covered to ;)

ok so insurance wont cover, mechanical maintenance, blah blah, ok

ordered a radio module from ebay, everything works and is back to normal :)
