Kenwood car unit with garmin navigation

I have a kenwood in dash car unit, a DNX521vbt, this unit has garmin navigation built in.

I have downloaded the danish map for testing,
placed the img file og the sd card in a /garmin folder, the unit regonizes the map.

BUT here is my problem.

it doesnt seem to use the highways in denmark. only the smaller roads??
with garmin map, a route = 2h 20min.
with OSM map, same route = 3h 33min.

the highways are visually shown on the map, but its not used on a routing…

what am i doing wrong?


I’m not sure but it looks like the Kenwood satnav is using a different profile then ‘car routing’. Maybe the routing profile can be changed on you satnav?
