Function restrictions

For safety reasons, some COMAND functions are restricted or unavailable while the vehicle is in motion. You will notice this, for example, because you will either not be able to select certain menu items or because COMAND will display a message to this effect.

To protect the integrated hard drive against damage, COMAND deactivates it at very high temperatures. The following functions will be temporarily unavailable:
• Navigation
• Voice Control System
• Address book
• MUSIC REGISTER
