Does the nuvi 200 have a off road setting to possible use on the trail?
The closest would be to put it in pedestrian mode.
Ya pedestrian is the best you will get and you will find it doesn't work all that well offroad. It will try to stick to close by roads and only jump to an actual location when you get far enough from the road that the unit calculates you really aren't on that road. As you get near another road, the "vehicle" may snap to the road as you pass it.
Since the 200 is an automotive GPS, it works on the algorithm that assumes you are always using roads, even when walking.
When I set my Nuvi 200 to Pedestrian mode AND select "Off Road" as my routing preference, it doesn't seem to show any tendency to snap to the roads.
That said,it doesn't display tracks which is a major limitation when retracing a trail, isn't very rugged IMHO, has limited battery life (4-5 hours) and the battery isn't field replaceable although you can buy an external 4xAA pack (~$25) and could use an extra zoom level or two.
I've got the Topo maps on a SD card and would much rather have it in the woods than be without a GPS but there are much better choices for geo caching etc.
Ah you know what. When I did this, I didn't think to change the routing preference to Off Road (didn't even know it was there) which would explain why mine kept trying to snap to the nearest road.
Thanks for clearing that up. I will have to try it again sometime and see how it works AFTER switching the navigation preference as well.
