So I've loaded a few routes into my Nuvi 550 and used the "my data" to load the routes. I also see how you can delete them from the "custom route" section. But when I go to "load from file" there are many routes in there - old ones, repeat ones, etc. Where on the device are these files and how can I delete them. I created a "test route" and there must be 5 test route files.
If you delete anything on your device using Finder, don't forget to also empty the trash. Unfortunately Apple saves all the files you delete in the .Trashes folder and sometimes the device will find them there.
