I have had the car for 3 months and it has been problem free. This is the first time anything strange has happened with the car. I did not loose power, all of the radio stations were there my home address was there the only thing that I noticed was after putting in the navi code my mileage history was gone and the milage for that tank of gas was reset.Only in the Navi system the milage in that dash was fine. Has this happened to anyone or does anyone have any idea what just happened. It has been 2 days since this has happened and the car is just fine again.
