Hello,
I just wanted to report a bug (I thing):
When the GPS is on (and center map selected), if I try to move or zoom the map (have tested with google maps sat view) I am getting a overflow error: invalid floating point operation.
I guess the map moveing/zooming should be disbled if the gps is on, or if you move/zoom the map then the gps should be disabled untill you put it on again.
