Why not use Google Maps on your phone for navigation? With Bluetooth to your radio, you get voice turn by turn on the car audio system. Just mount your phone so you can look at the maps handsfree. Is the Mercedes navigation better than Google Maps? $200 for a DVD is not very appealing. Do you get free lifetime updates for that price?
