Cycle Sat Nav

[Madbadger]

Now me and the wife are actually enjoying riding our ebikes, I'm wanting to buy a cycle sat nav. Am I correct in thinking the units will have all the cycle routes stored on them? and all you do is type in a destination and it shows you a map like a car sat nav does. I've seen a few on the net but I'm a bit confused in what they do, some say `Train` I suppose this is for competition cycling, that's not us, I just want it to show the cycle routes and how to get from A to B....

anyone got any advice on what I should buy

thanks
