Hey Community!
I will appreciate any information that someone can give me in how reading from differents maps. I will appreciate the map provider & version the idea is to extend the Roadnav usage range to others countries than the USA, using any map available.
Any experience, data or something to help me learn will be appreciate.

I know about Teleatlas, Navteq (these are good in europe and North America). But I have read about Garmin, Mapsource, Movimap, etc.
Any data will be appreciated.
