Dr. Gee and Statman,
I have a 2006 GX470 with Nav & RSES.
The hack works for me in park and while in motion.
These are the steps I follow:
1. Hit the "Menu" button
2. Press "Volume" icon on the screen
3. Press top left of screen
4. Bottom left
5. Top left
6. Bottom left
The service menu screen appears.
7. Press and hold "Override" until you hear a beep and the text changes from white to black
8. Press "Back"
9. Press the "Destination" button to enter desired destination.
As mentioned earlier in the discussion, the override will remain in effect until you turn the car off.
Good luck. Let me know if this works for you.
Antonio.
thanks!That was it. I was trying in the "sound" screen of the audio section.
