I am having problems with my ipaq rw 6815. i can't make gps work. i think it has something to do with a red spot on the upper right corner of screen. i have downloaded Navio, but nothing works. on a2b screen it says: error - no gps fix. please help! i also cannot connect to my computer by usb, but i could when i first downloaded navio and registered my product. active sync doesn't recognize my ipaq
