like nightwatch said......anything can be done, but at an expensive price; make sure you get it in writing. and trust me, the backup camera system for the M is amazing. id wait and get an M that is already equipped with it though.KarlDL wrote:Hungry sales guy claims that the backup camera can be added to a base '07 M35x once nav has been retrofitted. Comments on this forum indicate that the trunk lid isn't prepped for the camera in the base model. Is the sales guy full of it or can this be done?
