On the return to PA from Maine was travelling in Connecticut on I-84 when the Nav system just froze. Map would not change, controls would not allow me to cancel the destination and redo the directions. All other functions of the entertainment system were unaffected. I've shut the car off several times but it's still frozen on the map of I84 near Hartford.

Thoughts on options to reset the NAV system to see if that can fix it? Map update done three months ago with no problem since except for twice on the ride up to Maine last week the system reset itself twice with no adverse affects.

Your wisdom sought and thanks before I take it in to the dealer.

 

My standard reply for everything: disconnect the battery for 10 seconds.
