I have an Etrex 30 with a 16Gb MicroSd card.
When I connect my Etrex to my iMac I see (Garmin1) and Garmin.
The last one is the Microsd card.
I only want to store maps on the MicroSd card.
When I connect all routes and waypoints are copied from Garmin1 to Garmin
when I delete all files from Garmin and disconect to see what is on the device it looks OK but after I connected the device to Basekamp everything is restored again even files which I deleted permanently are back on the MicrSd. What is happening?
