Thanks for the confirmation. I am actually strongly considering to retrofit Nav as I want split screen, office and bigger screen display for reverse camera (scaled down to really small display on the standard screen) and surround view. I have checked bimmer-tech and the cost is like $28k with Map, Voice Control and GPS antenna but I am worried about installation and warranty as it is not a local company. Also check with another vendor locally quoting $32k with installation and 1 year warranty, but he quoted office is $5k on top of $32k, that is ridiculous given it should be standard with Nav if the car comes with combox.
Anyway, any reliable local vendors to recommend?
