I should be getting a NAV MK4 from my BMW dealer tomorrow. As a new unit, do you know it the unit comes with the DVD disk, or is that 'extra'? If extra, I may need to buy yours. I should know by tomorrow.
Are you speaking of the 2005 Navtek Navigation DVD? If so, does it also work for the 2000 M5? Just playing it safe since the 2001+ have difference Nav. screens. Also, I believe my Navigation runs on a CD based system and not DVD based. Correct me if I'm wrong.
