Thx.
I don't know if i understand correctly -The source for ...map(maybe)?
This is polish ca.3 years old map from Ekspress Map called ,,Sudety Zachodnie''.
It covers Izerskie Mountains, Polish and Czech(part) Karkonosze originally designed for Trekk Buddy. Then i conwerted it to OziExplorer then used in TwoNav. And Locus can read this rmap format -this is GREAT for me. I can see all my Topo Maps collection from Ozi and Two Navs here. The other important factor is that Locus can read ANT+ sensors which Two Nav doesn't .
Only I have to learn to make ,,order with Fields'' to have great cycling computer.
