bluetooth ecu
« on: November 17, 2015, 09:43:33 PM »
Hi alll
Just wondering if any X5 owners  have had experience with the Bluetooth  ECU  on the X5 I have been trying to locate a part with a specific Number.  I am listing it in the hope somebody might be able to advise me.
84 10 920 7075. It would seem that this unit controls the cd player and the sound on the Satellite navigation system. Must take a photo and post it (when I've washed and polished my baby)

The Bluetooth unit is a TCU or ULF depending upon the year.  What do you mean by 'controls' the CD Player and Satnav sound'.  All it will do sound wise is mute it during calls.

That part number refers to a remanufactured telematics unit.  Part of option SA633.

There are 14 different versions in use, 9 released in just one year.!!  BMW had real problems getting their Bluetooth system to play nicely with phones back then.
:type: Never anthropomorphise computers. They hate that.
