65 90... Notes on handling navigation computers

All model series: 

CAUTION: Risk of damage!
The navigation computer must not be disconnected from the power supply while the LED on the computer remains lit (the LED goes out after approx. 1 minute).
NOTE: To ensure full operation of all the communications components, it is necessary in new cars to insert a Road Map CD in the navigation computer.

This is absolutely essential as certain functions are disabled for distribution channels.

These functions will only be available again after a Road Map CD has been inserted. The mode preset at the factory is automatically reset when this CD is inserted.

Software installation: 

The navigation software must be loaded with terminal 15 activated and the navigation system ready for operation.

Make sure there is a stable power supply. If necessary, connect a battery charger to the vehicle.

The charging operation must not be interrupted (terminal 15 remains activated).

When replacing navigation computer: 

From E65/66:

E46 (with radio navigation) only:

When replacing navigation computer: 

"With radio navigation insert the operating software CD in the computer and wait until it is ejected. Then follow the instructions on the display. This procedure takes several minutes".

NOTE: The ignition must not be turned off and then on again during this procedure.
The software is loaded when the operating software CD is ejected.

If the software is updated at a later stage, the last step is omitted if the navigation computer is already configured for a navigation system (radio navigation or navigation system).
