Seems typically BMW over-engineered! $310 for a camera? ouch. I doubt the rear will be less than $600. I really wan to put in video inputs into the nav and a rear camera (I'm so tall, I'm looking at the ground unless I scooch - so the camera would be my full-time rear-view mirror).
Any other - more reasonably priced solutions? (the tv part alone is a ballbuster in price!)
