If you want to replace the head unit, you will require and adapter harness to match up to the Bose amplifiers.
A better solution might be to replace the head unit with another stock unit and add a Alpine 6 CD player in the trunk. I think there is a way to get an auxiliary input much like th guys have done on their F50. I fyou go this way, call Joe (

I guess you could go whole hog and go for NAV and satellite radio with BT and get a Pioneer AVIC Z-3. You will still need an adapter.
