I partly fixed my problem. I re arranged/deleted some favorites with Map Source and save the file as: current.gpx. I erase all my favorites in my Garmin flash memory. I then loaded the Map Source saved current.gpx file on my Garmin . Everything work fine except for one thing. I lost ALL my categories in which the favorites were under. For the future, is there a way I could I saved my categories as well as my favorites ?
