Hi FotoAir..
There has been a lot of discussion on the German MK site about GPS signals in Brazil. It is also an area heavily prone to GPS disruptions via solar flares.. Have a read in the 086 firmware thread.. I am sure there is a lot of info in there. MK adjusted the GPS settings in the early firmware to compensate for the problem..
