Maybe I'm over-egging this item a little, but it's actually much more effective than I thought that it ever could be.
OK, you load in waypoints and the arrow will give you the direction and distance to the selected waypoint. That's fine if you're out hillwalking and want to know how to get back to your car or camp. It was for this function that I bought the unit as I planned to load as waypoints the beginning and end of every Green Lane that I ride on and then to use the unit to direct me from the end of one Green Lane to the beginning of the next. If that fails, it will tell you your exact OS grid reference so you can look up your OS map.
But what I've been doing over the last week or so is to plot a route in MapSource using City Navigator v6. (To be clear, you don't get either MapSource or CNv6 with the Geko - you don't get anything at all - so you have to have bought another product with that software and mapping data).
Having loaded the route, the Geko uses the arrow/distance screen to direct you to the next point in the route at which you have to make a turn - as you approach that point the arrow bends to show the direction of approach and the direction you should take at the junction/roundabout etc (as shown in the picture in my first posting).
What PanEuropean says about directing you A to B to C to D is true, but A, B, C & D are always points at which you have to make some sort of turn.
It's quick and easy to create a route in MapSource and far quicker to load it into the Geko than into my 2610 (mostly because I have to plug the 2610 into the mains). The Geko also velcros in an instant to my DR-Z and off I go!
If this unit is a child's toy, then it's a pretty useful toy.
