If I recall correctly, you downloaded the Open Street maps for your Europe trip from the internet. I do not think you used Garmin Express.

I would suggest you do teh same thing you did last year, download a current map of where you want to ride here and install it the same way. I think the procedures you followed were a few threads in this forum, you could look for those for the procedures to follow.

If I am thinking of the wrong person that did that last year, sorry. My error.
