Every other satnav or satnav app I have used allows the download of a whole country, or even all of Europe in one operation. I was disappointed to find that I had to download every sub-region of every country separately, which has been a tedious process. I would like to see the option to easily download and also remove whole countries to make it easier to set the app up for a specific trip.
Incidentally, another topic mentioned that maps cannot be downloaded to an SD card, but my phone offered this option. (Motorola X Play running Android 6). I have my SD card set up as portable storage and have not used the option to merge it with the internal storage as one virtual storage area.
