has any one had any probs with this MIB1 Amundsen.every now and then my screen goes blank and if flashers every button i press does nothing seems like its fronze,,it takes about 5 mins before it will boot up again

Possibly the screen on its way out.  This does happen with MIB1 screens.  Consider going for an MIB2 screen as a drop-in replacement.  Asked @pab567 for further information.

The MIB1 screens are lower resolution so if you fit a MIB2 screen with a MIB1 glovebox unit you'll get duplicate images on the screen.
