A mate gave me a copy of Oziexplorer for my 7 inch chinese gps and after a bit of faffing about have got it working but cant seem to load the maps I want and find the whole interface rather challenging...

Definitely not a simple plug and play set up... very very detailed though and I think once it is mastered it would be a good bit of kit but bloody hell??

I have just about every map for Australia on it..... takes some time trying to find the right map.
