Hi Bmeggison,
Some older Garmin nüvi models do not support the transfering of
routes. However, you can still transfer all the
waypoints into the unit and save a bunch of time that way. If you have S&T 2010 you use the export to GPX feature and then drop this .gpx file into the ...\Garmin\GPX\ folder on your Nuvi.
See our blog post on this if you'd like more details:
How to send route points to your Garmin Nuvi
If you are not currently using S&T 2010 there is no simple way other than to "...
convert all the waypoints to lat/lon and then jump down turn around and pick a bale of cotton" as you have mentioned.:rofl"
