Recently bought a 2nd hand edge 705 and thought i would be able to put GPX routes from sites like Bikehike or similar onto it, but get a 'Only 100 points can be used for road navigation' message if I try to use them, do I need to buy one of the routable UK maps micro SD cards to be able to stick any GPX route on the thing and be able to use it, or do I need to use a garmin specific route creator to plan a route that can be put on it?
cheers for any help/advice!
