Route in Basecamp - Just a straight line

I installed an OSM into Basecamp, all went smoothly. However, when I try to build a route using two points, all I get is a straight line between the two points, it is actually not creating a route using the road system.

Do I need to do something different to get an actual route? I have selected the correct map.

Thanks

Please tell us where and how you got the map. I presume that yoou have selected the map for the vehicle you want to use? For example, a bicycle map might not allow to route on a motorway, no matter what vehicle you select.
