Could be a defective map card or head unit, or just a one time glitch. It may not have been inserted correctly and just wiggled loose. The first thing to do is pop out the map card and push it back in the slot until it clicks in place. If that doesn't resolve the issue, then a trip to the dealership is in order. One other thing, you must wait for the map system to completely load before trying to use it.
