Anti-theft Feature
The navigation system has a coded theft protection circuit. Be sure to get customer's 4-digit security code number before:
- disconnecting the battery
- disconnecting the navigation unit connector
- removing the NAVIGATION (10A) fuse from the passenger's under-dash fuse/relay box
- removing the ACC (7.5A) fuse from the driver's under-dash fuse/relay box
- removing the ACC (7.5A) fuse from the driver's under-dash fuse/relay box
After service, reconnect power to the navigation unit, and turn the ignition switch ON (II). Enter the 4-digit security code, then select "Done".
When replacing the navigation unit, be sure to give the customer the new anti-theft security code.
NOTE:
If the anti-theft security code does not activate the navigation unit, verify the code is correct one for the unit. Check the code against the navigation unit's serial number on the Acura DCS system. If the code is correct, replace the navigation unit.
