I have the Etrek Legend and it does do automatic routing but I prefer not to use this feature because it tends to choose fast highways.
I create "way points" on the computer screne marking each turn when creating a route. I save this route to my GPS and I'm done.
In reality, you really don't need this and a cheap used copy of MS Streets and trips will give you all the coordinate you need to type into the GPS and do the same thing.
