bought 2008 bmw 750li (e66) no navi dvd. North Americia is what I need. any help is apprecatied

For E66 you need the version high , update first your sistem car if you have a copy off the disc not the original .
You need tot test youdr dvd cd unit if is ok , with an original dvd disc , maybe cd disc read id but dvd not , try this .
