Navigation frequently asks for anti-theft code and needs GPS initialization
NOTE:
- This is often caused by a loss of battery power, a low or poor battery condition or a poor ground.
- Always make sure that the correct DVD color and version are installed.
- Check any official Honda Web site for more service information about the navigation system.
- Turn the ignition switch to LOCK (0).
- Disconnect navigation unit connector C (8P), and check for loose terminals.
Are the circuits OK?
YES - Repair or replace the loose terminal(s).
NO - Go to step 3.
- Turn the ignition switch to ON (II).
- Measure the voltage between body ground and navigation unit connector C (8P) terminals No. 1 and No. 2 individually.
Is there battery voltage?
YES - Go to step 5.
NO - If the +B wire does not have voltage, repair an open in the wire between the under-hood fuse/relay box and the navigation unit. If the ACC wire does not have voltage, repair open in the wire between the under-dash fuse/relay box and the navigation unit.
- Measure the voltage between navigation unit connector C (8P) terminal No. 4 and body ground.
Is there 0.2 V or less?
YES - Replace the navigation unit.
NO - Repair open or high resistance in the wire between the navigation unit and body ground (G504) (see DASHBOARD WIRE HARNESS (VIEW OF MIDDLE) ).
