Suffice to say that it would be a MAJOR job and very costly if you purchased parts from BMW...I'd suggest a nice Garmin or just trade cars for one with the factory NAV. Problem is - updating the maps in the factory system is REALLY expensive ($300+ every time), whereas a lifetime subscription from Garmin is only around $80. Plus, you would have to also add the iDrive components to control it.
BTW - looks like our cars are VERY similar, including that front lip, wheels, color, etc. You have black interior and brushed aluminum trim too? And...I'm a CT native, although from up in the NW area of the state.
