Hi my current head unit (BMW business) does not have Bluetooth or any AUX functionality. Would really like to have these available, which got me wondering would the next head unit in the production line (BMW professional) firstly fit and secondly be compatible with the existing wiring.
So if the above answer is no, what would people's recommendations be. Would the pop up nav unit be an option??
Have made many calls and looked on google for an answer but can't seem to find anything conclusive.
Cheers
Fants.
