Ok i do have a GPS, well my nokia phone does, good for telling taxi drivers where to go but no good for my bike. been looking at the COLORADO 300 HANDHELD among others, i want a colour screen becasuse it is pretty. needs to work in remote areas (outback tracks) etc. waterproof etc etc. What do people advise for a GPS newbie? there are a few models with seemingly not much difference between them. Anyone got a 300? Also Oztopo seems to be the map download to go with as far as i read? Ps i will also use this for bushwalking, do i download other maps for those tracks? Any advise would be appreicated.
