[Closed] GPS- Don't have a clue

Garmin Dakota or Oregon show OS maps (although you have to buy them extra) - pretty sure you can use MM - I'm using Mapquest Quo

You can't load the MM as such into a Garmin, only the route you have prepared on your PC using MM Navigator.

You can download to an Iphone though with MM's app.

That's how I see it (waits to be corrected) I'm on the learning curve too.

You install a mapping programme on your pc - memory map, quo, etc (there are lots) - you plan your ride, then you load the route (not the programme) onto your map in the Garmin.
