Thanks Sergio2,
it worked!

I have the map running in Basecamp. Just a question, I have not yet read the article about ActiveRouting, but can you already tell me where I can find the ActiveRouting function in this map of France v3? When I zoom into the map I can see for example a red dashed line with the text "GR 2a", when I put my mouse on this line I find the info that it's a "Trail". My viewpoint of ActiveRouting is that all the marked trails (named trails) are also put in the Garmin map. Is this correct?
it's there a way to find all the trails around a area?

thanks
