@Jörgen Hi Jörgen. That does look great, and as a Nav6 and Chigee user, I still look enviously at the large Android tablets.
But do you not worry about the screen attracting trouble when the bike is left? We all worry when we're leaving the bike over night in a car park, but I can't help feeling that a permanently attached Android tablet just attracts even more yobs who'll try to wrench it off to steal it.
Maybe I'm just a worrier, but I need navigation for my touring bikes, and those always get left out over night. I'm always pleased to unclip my Nav6 or Chigee and put it safely in the hotel room.
