Once in a while you will see that the GPS refuses to calculate a route, make long detours or just draw a straight line between the start and destination of a route. There can be several causes for this behaviour:

Settings in the GPS unit or Basecamp/Mapsource are not correct / optimal

Broken road network on Openstreetmap

Routes are too long to calculate

Car routing is not supported

Limited use for Walking/Hiking navigation 

Device transfer options (Basecamp 4.3.3. and later)

Different OFM version on GPS and Basecamp

Route chaos: OFM version from Basecamp and GPS are not from the same date.
