Who makes 'em?
Touratech, for one, any others?
I need to get a sat nav sorted for my Blood Bike group, the bike will regularly be left outside hospitals etc, and since a) it isn't owned by the rider, and b) they'll often be on an urgent delivery, be very easy to leave the sat nav behind. So we want (need) it to be in a lockable cradle, to stop at least casual walk by thefts.
Any info / experiences much appreciated!
