Yes, there are many of them. For example, the 1490 1690/95, all of the 3xxx models and all of the 2xxx models. You're probably best to go to the Garmin website and review the specs for the current available models. You're looking for any model that lists a number like 10 or 100 under the spec called ROUTES.
Also, when looking at your earlier post I see that you can see a File called Test.gpx which you believe to be the file sent from S&T. If that is the S&T file, find the file on the Nuvi and rename it TEMP.GPX. Then reboot the 1390 and go to Where To - Favorites and see if the waypoints in your test file appear there. Normally, on boot up, the Nuvi will look for a Temp.gpx file and if one is found it will take any waypoints it finds in that file and insert them as Favorites on the device (include them in the current.gpx file which is where Favorites are stored). You still will not have a actual route to follow, as the 1390 doesn't support that function, but you may be able to send individual waypoints from S&T to the Nuvi and route to them one at a time by selecting them from your Favorites list. Worth a shot anyway.
