I create different tiles setting the Splitter to 1.600.000, then I add clipped contours and DEM with Mkgmap.

I transfer the map with Basecamp/Mapinstall, both in the latest version available.

When I click the button for a partial install, I can choose my map or the other I have installed. If I choose one of the others, such as Freizeitkarte, I get a full version of the map (I am working on Italy) divided into tiles, and I can select which ones I want to transfer to the device. If I do the same with my map, I get it already completely selected: I see the tiles, but I cannot select some of them, so my only option is to trasfer full Italy to the device.

I tried many times and in one of them I was able to select the tiles... but I don't know how ! And then the map on the device wasn't complete: I had the selected area, but the contours and the shaded reliefs were not there.

I am trying to do a partial selection because my map is slow when I use it on my Garmin: when I scroll the map I have to wait a few seconds to see the image, while with Freizeitkarte the loading is almost immediate. For this reason I would like to try to upload a small part, to have a lighter file. I also tried to edit my style files, removing all the objects I don't need, but it doesn't help... 🙁
