Thanks for the info on that. Thats why I'm asking now, because I don't want to invest the time and money and learn the hard way.

I checked out the Openecu.org website and I like the idea of using free maps etc. However there isn't much in regards to how to actually use it or up load a map.
So I'll keep working on that for a while. Any help or hints to use these would be greatly appreciated.

Thanks again for all the advise!
