Came across this on the 4GIS subforum, not sure if this will apply, but hopefully?

I'll be trying this later today.

"Steps to enter into the Hidden Navigation Diagnostic Menu
1. Press and Hold the "MENU" button
2. While still holding the "MENU" Button, Cycle the "Parking Light" Switch ON then OFF
3. Cycle the "Parking Light" Switch ON then OFF three more times.
4. Once you see the Menu appear you can let go of the "MENU" button"


*Enter this Menu at your own discretion. I am not liable for you messing with things in here and breaking your Navigation stereo.
