yes I see the original mb nav everyone brags on when selling is brick by current standards. About as useful as the silly third row seat which will become a toolbox once I get the car..I see these new Android units run less than $500 and are awesome. Also incorporate a backup camera and TV if you want..

The electronics techs on the MB forum have it all sorted out and lots of instructional videos on YouTube..I dont use a smart phone but its just a cheapie..very slow. And want something built into the car..not a separate screen but yes, I see most find that the easiest..Thanks for the great info!
