Global Positioning System: Service Precautions

General Operation
Refer to the Acura Navigation System Owner's Manual for the navigation system operating procedures.

Anti-theft Feature
The navigation system has a coded theft protection circuit. Be sure to get the customer's four-digit security code number before:
- disconnecting the battery
- disconnecting the navigation unit connector
- removing the No.56 (7.5 A) fuse from the under-hood fuse/relay box

After service, reconnect power to the navigation unit, and turn the ignition switch ON (II). Enter the four-digit code, then select Done"

Service Precautions
Before disconnecting the battery, write down the frequencies for the radio's preset buttons.

After servicing, park the vehicle in an area where the GPS satellite signals will be unobstructed, and check the satellite mark on the display.

When the battery is disconnected, the clock is reset to "0:00." The clock will reset to the correct time after the system receives the GPS satellite signals.

After reconnecting the battery, you have to wait to get an initial signal from a satellite. This takes about ten minutes.
