I'm a reasonably proficient user of basecamp but I have experienced an issue recently. I updated Basecamp (Mac) from 4.6.3 to 4.7.0 and also updated the maps to City Navigator Europe NTU 2019.2.

There were two versions of the maps installed on the Unit and three versions on my computer, one seems to cover Eastern Europe and the other Western Europe. This caused me a big issue when travelling from UK through France (one side of the map) to Germany and Italy (other side of the map). Each map only has detailed roads on one side, the other side is basic towns. Each version also 'compresses' the 'wrong' map making it narrow.

When I make a route in Basecamp on the computer (with the detailed map) it works fine but when I transfer to my unit it makes a crazy route with straight lines, i.e. not following roads.

All the Navigation settings are identical on both.

I read that reverting to version 4.6.3 might resolve this but it has not.

I am using Mac software Yosemite 10.10.5

I've included screen shots to show the difference when I switch between the 2 installed versions of the maps on my device.

Is the best thing to uninstall everything, delete the device off Garmin express and start again.

Ideally I'd like to delete the maps on both Basecamp and the Device and reinstall them again.

Annoyingly I lost a lot of old motorbiking routes I'd plotted when I reverted my basecamp version, is there a way to save these before I start (I can probably find them again from emails etc if necessary)
