For the last week every time I try to program a destination in the navigation, after I input the destination and the program is finding it and trying to map a route to it I get the message "unsuccessful, try again." No matter how many times I try or what address I input or if it's a sunny day or cloudy or if I'm close to a building or not I get this message. What is stranger is if I drive the car for maybe 20 feet it finds the destination and maps normally.
