The most important thing, I think, is to understand where you’re going, and vital to that is to have a good map system. I have played with most of them, and finally settled on Mapyx Quo. I will document all our walks using Mapyx Quo files that you can download, and provide GPX files that you can download to your GPSr.
There is a fabulously simple interface for just buying the map tiles you need, and you can then print out just the bits of map you need for your walk.
