: Bluetooth - upgraded TCU - dealer opinion

08-05-2005, 07:38 AM
2005 M3 Convertible, built in 03/05, Motorola MPX220 phone does not connect for bluetooth. The dealer told me there is a new TCU since mine that has been upgraded that may work better. My phone is not on the Yes or the No list.

Anyone have experience with this?

Depends on what's in your car....the last 3 digits of the TCU will be either 993 or 114. They apperently have an even newer one out now as well (056). Prolly won't make a huge difference though. Read up here on all of this:
