Hi all, i have been looking around the market for a while for a Nav Unit for my Mercedes.

Im thinking about getting the F90-BT, since no other brands NAV unit has these functions.

Is there anything i should also buy together with the unit for the install.

Im thinking of getting:

1)Back-up Cam

2)Steering wheel controls

BTW: my car came with the factory BOSE. Its an '02.

Thanks All!

looking foward to hang here!

Don't know about steering wheel control but I connected my f90bt with pioneer back up camera. Works like a charm. I am loving the set up. You can read a lot of review for this unit on this forum. Even though it's far from perfect, I am actually happy with the unit.

I got a CCD back up camera off eBay and it's excellent. Just about any camera with a video out RCA plug will work.

I believe there are different wiring harness for this unit to work with different cars. Try crutchfiled to find a part number for yours.
