I am trying to download layers in high resolution for my Trail Tech Voyager Pro. using the ipad or iphone, i can download the layers in high resolution, but they download as individual tiles. that doesn't work for my Trail tech. it has to be in one file. when i download from the computer, it will download in one file, but does not give me the option of high resolution.

   Good morning,
   You're accidentally making an apples to oranges comparison here. Tiles downloaded by the app for offline use are for use by the app and are packaged and created in a way that our app can use them.

   For use in outside devices such as the Voyager Pro you need to create a MBTiles package of the area you want to see using the Print - MBTiles option. For resolution Z16 tiles are what we call high res in the app (at the equator) and give about a 2m resolution. Z15 would be about equivalent to the 4m standard resolution (at the equator). The further go from the equator things get a little more complicated.

   Best,
   Ben
