TCU are inherently much more expensive than ULF's just because it is a telematics unit and not a BT unit only (like the ULF).
So this new Sept 2007 TCU seems to me like a regular TCU revision and not a new addition to the ULF/TCU Bluetooth options.
Wow, thanks a bunch for the info. I am gonna have to call bimmernav tomorrow and get everything straightened out before I take the plunge.
