- After troubleshooting, enter the anti-theft code for the navigation system.
- In the set-up/colors menu, make sure that both the day and night map background colors are not set to white.
- Full brightness on the instrument panel brightness control with the headlights tuned on causes the system to stay in the day mode, even when the lights are on.
- Check the vehicle battery condition first.
1. Turn the ignition switch to ON (II).
2. Make sure the instrument panel brightness control is not on full brightness. Turn the headlights on, and adjust the dash brightness to the middle range.

Does the display change to day and night modes when turning the headlights on and off?
YES - The system is OK at this time.
NO - Go to step 4.
4. Go into the Diagnostic Menu, and use the Car Status test to check for an ILL signal.
Is the ILL signal OK?
YES - Replace the navigation unit.
NO - Check the ILL+ circuit between the navigation unit and No. 14 (7.5 A) fuse in the under-dash fuse/relay box.
