Older Garmins : it seems some Garmin's cannot import the "routes" we use in our GPX files. We are considering a GPX "track" version.
How to use GPS data
The Android and iPhone apps, and GPS devices like the Satmap 20, work while you are out walking as the maps are stored on your device, i.e. they don't use 'data', and you don't need a signal.
The best bit is the 'you are here' symbol on the map! Also, taking a powerbank with you is highly recommended!
Apps - OS maps
android iPhone PC
OS Maps Online - a website for planning routes, and an android/iPhone app with OS 1:25K and 1:50K mapping.
Apps - OpenStreetMap
OpenStreetMap is a global free alternative to OS maps. It's more accurate in places, but doesn't have rights of way information. Brilliant for when you go on holiday!
Maps.me is a free Android and iPhone app. It uses OpenStreetMap maps, which are also free.
Easy to use. Works with our KML files. Doesn't have contours.
Orux Maps free
Dedicated GPS Devices
Satmap Active 20
Satmap Active 20 is a dedicated, rugged, waterproof, walker's GPS device. £285 with Openstreetmap mapping £360 with OS mapping.
Very good but very expensive
