This the 2nd time my Garmin Nuvi 2565 crashed, the Garmin map disappear from the screen, but when I removed from the cradle, the map reappear again.

I even upgraded to the latest firmware and also did the factory reset (ie. hold on to the bottom right corner while power up the GPS), but after a few weeks later, the map disappear again, but when I removed from the cradle, the map reappear again. Why is that so?????

Is there a problem with Garmin 2565?
