Navigation frequently asks for anti-theft code and/or needs GPS initialization

WARNING: This page is about a different car, the 2011 Honda CR-V and 2010 Honda CR-V. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

Check the vehicle battery condition first (see BATTERY TEST ).
Check the connectors for poor connections or loose terminals.
This is often caused by a loss of battery power, a low or poor battery condition, or a poor ground.
Make sure that the correct navigation DVD color and version are installed.
Check any official Honda service website for more service information about the navigation system.

Check the No. 23 (10 A) and the No. 17 (15 A) fuses in the under-hood fuse/relay box and the No. 34 (7.5 A) fuse in the under-dash fuse/relay box.
Are the fuses OK?

YES -Go to step 2.

NO -Replace the fuses.
Turn the ignition switch to ON (II).
Measure the voltage between audio-navigation unit connector A (24P) terminal No. 24 and body ground, and between terminal No. 14 and body ground, and between audio-navigation unit connector C (8P) terminal No. 1 and body ground.

Is there battery voltage in either terminal?

YES -Go to step 4.

NO -Repair an open in the wire(s) between the appropriate fuse/relay box and the audio-navigation unit.
Measure the voltage between audio-navigation unit connector A (24P) terminal No. 12 and body ground, and between audio-navigation unit connector C (8P) terminal No. 4 and body ground.

Is there less than 0.2 V in either terminal?

YES -Replace the audio-navigation unit (see AUDIO-NAVIGATION UNIT REMOVAL/INSTALLATION - ('10 MODEL) ).

NO -Repair an open or high resistance in the wire between the audio-navigation unit and body ground (G504) (see STARTER SUBHARNESS ('07-09 MODELS) ) or audio-navigation unit connector C (8P) and body ground (G502) (see STARTER SUBHARNESS ('07-09 MODELS) ).
