Not everyone wants 'routes'.
A very large number of outdoor enthusiast love the Nuvi series.
But, once you offload tracks, you can never get them back on and visible as a trip log ever again it seems.
You would think you could since mapsource allows you to upload tracks to GPS. But the tracks are not visible with trip log visible option on.
Once request. Allow tracks edited via Map Source to be uploaded back to the GPS and actually be viewable on the unit again.
I would be happy even if there is a manual method. Please tell me there is a manual method available and I will follow the steps.
