I picked up a TCU for my 2000 M5 (12/99 build). I also picked up the 25 to 54 pin adapter, BT antenna and BT cable... I plugged it all in and phone paired up right away. Pulled my contact list down as well. I used the telephone section of the nav screen to call my wife, she could hear me but I couldn't hear her. I tried the sneezing man, radio muted but I didn't hear a beep.
I went into the service menu (or whatever they call it) to see if any settings were in there. I saw a NAV Volume and decided to try turning it up, as I turned it up (while on a phone call) I could hear the caller in the background as the caller said "Softer/Louder"...
I assume all this means I need the SES Jumper, which is fine, but I CANT find the blue connector that it would plug into. I pulled all the brackets out including the DSP amp and the only blue connector I see is the little on on the GPS CD unit. I assume I would still here phone call if it was a Voice Recognition programming issue right?
Where could the cable be?!
HELP Please!
