well I just got a TCU from a 2005 M3. Here are the specs:TELEMATICS CONTROL UNIT CDMA Sep-04 Feb-05 84116946993 1st release of integrated BT/Assist TCU.
The telephone module i now see on the dash. I turn on the ignition press R/T, it says activate phone. I scan for the bluetooth with my phone but it doesn't see it. Do I need the pairing button in the console which I don't have or am I missing something here? I have everything else prewired from BMW, Antennae, mic etc as the car came with BMW assist, my module didn't have Bluetooth. I just swapped modules. Any thoughts, do i have to turn on Bluetooth with a scanner or am I just missing a step?
