I recently had some body work done on my Prius--a coyote jumped in front of the car on the freeway and took out the radiator. After the work was completed I discoverd that the navigation system has a problem. It correctly displays the current position of the car on the map, but cannot correctly find destinations by address or POI name. For example, I drove to the parking lot of a Safeway store, pressed the Dest button and had it find "Safeway". It found lots of Safeways, but the closest one was 2400 miles away! Is there some sort of fix or reset that I can perform on the navigation system, or do I need to take it to the dealer for repair?
