It's not necessary to create bigger maps, because Run.GPS stitches them together on the fly. Just put all map tiles in the 'map_images' directory and select how many map tiles should be displayed at a time.
If I want to have bigger resolution on my maps I have to put toghether more screens
Is there any SW for putting toghether more maps? As OZI mapmerge or similar? When I download more maps for one trip which is close one to other - can I made one bigger map with whole area? Thanks for that excelent program.
