If COMAND is equipped with a navigation system and has GPS reception, COMAND automatically sets the time and date. You can also adjust the time yourself in 30-minute increments, but the date cannot be changed.

If you set the time in 30-minute increments, any time zone settings and settings for changing between summer and standard time are lost.

The following navigation system functions require the time, time zone and summer/standard time to be set correctly in order to work properly:
• route guidance on routes with timedependent traffic guidance
• calculation of expected time of arrival
