I installed a new micro chip in the GPS and tried to download/save a route from Basecamp to the GPS.
Basecamp appears to download the trip and does not produce any errors.
So I installed the old micro chip and the Garmin Nuvi can't see any of the old saved trips either (if I look at the files on this chip through Windows I can see that there are many route gpx files on it.)
Is there any fix or reset to correct this problem?
