Question about DVD Nav
Can I replace the NAV drive without disconnecting the COMAND unit? My thinking is that the car would be turned off with no key in the ignition. I am trying to avoid having to put in a code for the radio. I think there is a 12v supply to the COMAND unit at all times, since with the vehicle off, I can turn the radio on just by pressing the Power button on the COMAND unit.
Has anyone replaced the NAV processor in the COMAND unit? What is involved?
What is involved in removing the Nav processor from the COMAND unit, and can it be done without disconnecting the battery?
