The latest NAV TSB upgraded the map discs & firmware, but eliminated the service menu with the override feature that enables a passenger to change the nav while the vehicle is in motion (because the driver should be paying attention to the road). Several people have been looking for the new backdoor for the service menu, but I have not seen anyone have any luck. Toyota could not have completely eliminated the service menu altogether. There has to be a new way to backdoor into it. If anyone has figured it out, please post the fix.
And if you have not done the TSB & you were not aware of how to get to the service menu, here is how to get there...
