Thanks Triple f,
Well I manage to trie it too, and confirm what you have said., Although i was a bit confuse because at the first time the unit became very very slow. Only the day after the unit became "normal". I tried that the unit work with basemap 5.01, to see if I could speed up the unit, but I couldn't upload it neither trough the usb, neither trough the SD. Is there a way to upload the basemap to the unit?
