I just tried MapQuest but I have one problem
I put in the start & end addresses then MapQuest routes it for me.
I drag the route to a different road (off the highway) then send that route to my GPS. I get the first route that MapQuest routed not the one I manually changed. I tried to send it as a route first, then as Waypoints. Both ways I send it I only get the original map before I rerouted it to better roads.
How do I get it to send My changed route?
The correct strategy is to give the Garmin a set of way points, in order
, that constrain the route that it can generate, then let it generate its own route. If you try to send it a route, it comes in as a billion way points and will overwhelm the Garmin and it will sit there a while then say it can't generate a route.
From Google Maps, you build a list of what it calls place marks. Then export that list to the Garmin. It will treat them as way points. If you have chosen them well, grasshopper, you will get the route you want.
The details of getting the Google place marks into a Garmin .gpx file can vary but that's what you're trying to accomplish. My current fave is to use Tyre, but it's PC only. On the Mac, you can export the Google Map as a .kml (Google Earth) file, then use the web interface to GPSBabel at http://www.gpsvisualizer.com/gpsbabel/
to do the conversion to a .gpx file that you can hand to the Garmin.
I'm sure you can find a similar approach that will work with MapQuest, but I haven't used MapQuest enough to know the details. I will try to research it a bit this weekend.
We can do a walk-through at breakfast on Sunday if you'd like.
