Many people ride with a Garmin GPS unit. Some people have Garmin Edge 500 or 510, these don’t provide a map display. Some people ride with a Garmin Edge 705, 800, 810 or 1000. These do support maps.
Some people with the map supporting Garmins do not have the maps as the Ordnance Survey map bundles are pricey. Some people aren’t taking the upgrade plunge because of the map price.
Fortunately, thanks to Open Street Maps, there are free suitable maps you can use. Frankly, it’s a bit confusing finding out what you need and how to use it.
So this is it boiled down for cyclists in the UK who want a “just get me mapping option”
- You need a MicroSD card to go in the Garmin. You may already have one. You only need a 1gb one for the maps I recommend. An 8GB Sandisk high quality card is less than a fiver from Amazon
- You need to download the maps, I use and recommend Talkie Toaster’s UK Contour Routable maps and have ridden with them for years now. Download this file. Or if you know what you want look here.
- When you download the file, it’s a zip file, extract the file there should be a GMAPPSUP.img file in it. That’s what you want.
- Follow from Step II here.
You now have free maps on your Garmin.
