I inserted inter point in road 451 (Vestvejen) and OsmAnd setted a trace correctly.
I had setted car option all the time.
I do not know why OsmAnd without intermediate point, setting route in that way.
Maybe is somthing wrong with speed limit.
By the way thank you for your help. And sorry for my perturbation.

When I try set trace from Glued to Billund application (OsmAnd) leads me via side roads. It is not have sense. And that happen even when I drive in main road. Application all the time want from me turn to on the side roads. But when I pass the last roundabout, aplication show me right way. Somwhere in map have to be mistake.
