Edge 840 No GPS or Satellite Connection - Update 27.13

Hello, 

Recently I updated the Edge 840 to the 27.13 firmware and now I have no GPS or satellight connection. The map's blue arrow has a flashing red question mark in it, the banner at the top says "acquiring satellites", the map thinks I'm in the US (I'm not), and I get the message that "Some navigation features may not work correctly in this aread due to missing map coverage".  However, I've updated the maps, did a factory reset and checked the maps again. Went outside to an open space for a while to see if I'd get a connection but with no luck.  Any suggestions on what's wrong and how I can fix this?

Cheers

S
