(DG) eS7 hybridtouch not booting up with maps

[landonshaw]

I have a new hybrid touch eS7, less than a year old with charts of the caribbean. I will have everything working and shut it down. The next time I turn it on, it goes directly to the charts but with no charts, just a very crude chart. I am also unable to use any of the keys. As though it is frozen. I then have to turn the power off to shut it down, or sometimes hold the button for a minute or so might work.

I try again and again to boot up, finally it will. There are other times that it will boot up with no problem.

What is happening?
