I have recently gotten a nuvi 255w and wanted to plan a custom route on MapSource via the Routes ability. Then I want to be able to upload those routes exactly to my nuvi. However I have found no way of doing that. All I have found is to upload Waypoints and then have to manually designate "via" points in order to force the 255w to go the custom route I want it to go. (I know the better way to drive around some things than it does when going through town)
Does the 255w have this option to follow custom routes created on MapSource? If it does, how do you get it to work?
If it does not, I would like a list of Garmin nuvi devices that actually do this. I see that devices like the "Garmin nüvi 765/765T" have an option called "Multi-Destination Routing" and has an option for only 10 saved routes. Is this the option I am looking for to upload custom routes from MapSource to the Garmin device?
And if so why wouldn't Garmin allow you to expand your 10 routes to more if you add an SD card and expand the storage? Seems like a no brainer to me.
Cheers.
