I noticed when I use the random course calculation option, it's practically always giving me the same routes. I live in a country with tons of cycling roads.
I also noticed when I enter starting direction 'North' it can't find any route, it just keeps calculating for 10 minutes and then it's giving me a 'route calculating error'.
When using Garmin Connect in a browser, it's giving me tons of different routes, also to the northern direction.
I'm using the Garmin EU map. Does this have anything to do with the map I installed? I also turned off 'use popular segments' but that doesn't help at all.
