Navigation Display Problem Gx470

[philly777]

Hello:

Could anybody please give some advise what might went wrong prior I take it to dealership to check.

The Navi display seems to work incorrectly (GX470 2003). Whenever I start the vehicle and hit the "Agree" button on Navi it stays normal on Map display but I can't enter/hit any Dest or Map button (they give beep sound but doesn't switch the screen). And few minutes later while driving the screen goes back to Welcome "Agree" button again. All Climate, Audio buttons work well. It started to work awkward out the blue.

Any thoughts on what I have to check please. Any other suggestions on what to do....

Thank you!!!
