BMW X5: Navigation Systems
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:
- Carry out coding of navigation computer with aid of Diagnosis and
Information System via "CIP".
To E65/66:
- Carry out coding of navigation computer with aid of Diagnosis and Information System in path "1 Recoding".

- The following note appears from DIS CD 25 software (and higher):
"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.
- Carry out coding of navigation computer with aid of Diagnosis and
Information System in path "1
Recoding".
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).
