Hi guys - have just acquired a 2005 pre-facelift E85, with MFSW, factory-fit bluetooth and standard Business CD stereo.
I've managed to pair my Blackberry to the car but will be swapping out the stereo for an aftermaket Kenwood unit, which has bluetooth in addition to DAB etc.
Two questions:
Is it possible to retain the factory-fit bluetooth with the Kenwood stereo, using the MFSW to control both?
If it is possible, which way would you go - fully Kenwood or mixed set up? (I know the Kenwood bluetooth works fine as it came out of previous E85).
I guess having the hybrid set up would mean the music volume wouldn't automatically drop when a call came in?
cheers
EDIT - D'oh! just realised that Bluetooth streaming won't work with the factory system
so that gives me my answer
