Garmin 645 music blue screen and nothing on the display but that blue back light

Hi there,

My new garmin 645M has frozen 3 times on me now.  I really need it for obvious reasons...The last 2 times it came back working all by itself.  I have no idea wat fixed it.  This time nothing is happening after 2 days.  My watch is on and as I know the button combinatios I can actually play music and record an activity but the screen is blank.  Has anybody else had the same issues?

  • Ive reset watch and restarted countless times - no change
  • Although it is recording activities it is not gathering GPS data to provide a map - there is no map on strava when it syncs
  • The gps data as I ruhn is off - the miles aare not full miles at all!
  • There are no buttons stuck and the watch is not damaged in any way
  • I've tried all update methods and to no avail

I think I'll just be taking it back to the shop as its only 6 weeks old.  Any ideas on a quick fix?
