For some reason I missed the photo of the nav yesterday. This raises some questions for me knowing what I know about the stock system. Fitting a unit like that may have, and probably did, require modification to the ducting for the climate control. And, then is the factory bluetooth still in tact or does this aftermarket headunit handle that duty? Is there any more audio equipment in the car? Amp, speakers, sub? If so, how good is the install?
Was the car originally equipped with factory nav?
