Please remember this car is a MY1999. I don't think BT was an option, it may well be the Nokia car kit was fitted. There is evidence of a car kit in the passenger footwell, a Nokia but possibly aftermarket. Still don't know why I have no BMW phone prep wires.



I've had the TCU apart. The TCU Has Black [GSM 1], Blue [GPS-US Only], Violet [GSM 2] and Cream [WDCT/BT] Fakra positions.
Here you can see the GSM/GPRS module, with connections for two antenna.

Cream is the bluetooth.

Since this is an EU model, there is no GPS [blue]




Being that the ULF/TCU wasn't available until 2001, I would have have no BMW GSM sharkfin (wasn't available?) [I have a Hirschmann GPS/GSM (SMA/MCX)], I gotta wonder where those Blue and violet wires go. lol! I guess I have to take off the rear parcel shelf
