Re: "Map-Biased" GPS?

Use a "topo" map in your GPSr?

Per colinh:

That's part of it.

The biggie, though, is how to lay out a route in - say -
GoogleEarth, and then transfer the route to the GPS.

The only GPS's I've used compute their own routes - the user
supplies a destination and the GPS computes the route from where
it is at the time to the destination.

OTOH, I'm talking a route that is totally determined by the user
and not necessarily using any path or road recognized by the
GPS's map database.

With Garmin's more advanced units you can specify any starting point (not
necessarily the current position), a destination and any number of 'via
points' in between. The gps will then compute a route between these points in
the order that you have specified.

Dunno about "Garmin's more advanced units" - my humble Nuvi 250 does all that.

Yes, I remember now there was a previous thread where someone pointed out
that you can actually use multiple via points on the Nuvi 250. (The manual
implies that you can only insert 1 into the current route.)

To be useful though you really need to be able to edit and save the route if
it doesn't start from your current position.
