2004 E55 Navigation Upgrade
The one I'm looking at has the command type of display, but when I hit the map button, it says nav not installed. There is also a disc slot at the top of the unit...
He said I could go to the dealer and have them just put in the disc, and I would then have navigation... is this true? Is the system easily upgraded from the dealer?
thanks!
If that unit is not there, you would need to buy the drive unit, the antenna, splitter and Nav disc.
anyone have the dealer install nav in a 2004 E55 that came without?
