Has anyone noticed whether their fuel economy display won't stay on when driving if the radio is on. If the radio is off, it will stay on all the time. Do I have a problem or is this normal?

 

Mine does the same, I've noticed it will stay on when the radio is on, as long as your not moving, once you start rolling, it turns the mpg off.

 

that is odd

 

With the NAVI system, the trip button brings 2 different "trip" menus, followed by a MPG menu with total miles left in tank, current mpg via large block yellow graph and accumulated overall fuel MPG, which can be reset. can be selected for continuous viewing.
