City navigator Europe NTU 2024.10

I recently purchased the online version of city navigator europe NTU 2024.10 and downloaded it to a SD card in my Montana 600, after the download the maps are in to parts all north and all south open in basecamp and plotted a route across France Belgium and Holland first part of the route up to the Belgian border were fine the second is were I discovered two problem 1 the two maps don't line up and because of that all i am getting is a straight line between towns in France and Belgium and I have to switch between both maps to get better detail. Anyone come across this and if so how do I sort it planning a trip to the following places in July France Belgium Holland Germany Austria Italy and back through France so need to plan the routes pretty soon.
