Bluetooth pairing but no audio--ready to break it

[apocalapsi]

I have a 2004 X5 E53 that I successfully swapped out my late 2003 TCU that only had Assist, for a late 2004 TCU that had assist and bluetooth. I was able to pair it successfully and it even loads my directory onto the NAV screen. After three months of working it quit. I then noticed my audio on the stereo quit too. I found under the spare a bunch of water and i was curious if it affected the radio module back there. Anyway I puled out the 10 amp fuse for the radio module and presto the stereo audio started working again. I have not been able to get the audio back on the telephone. It pairs and dials out fine , I just don't have audio. I am baffled. All the fuses are fine. The only thing I can think of is, I didn't locate or deal with some mention about a SES jumper. I have read that this has to be installed to get audio and I didn't pursue it as everything was working fine. IS it possible the water affected the radio amp? If that was the case then I wouldn't have stereo audio right? Any way I am ready to break it into fifteen pieces just to feel better..lol...Any thoughts would be greatly appreciated.
