Hi there and welcome
To do this, please do the following
1. Connect the Garmin using a USB cable 2. Click start, computer
3. Go to Nuvi drive and then open the Garmin folder 4. Copy GPX folder (Ctrl-C) 5. Copy the GPS folder to your PC 6. To add the favorites to another unit, open the GPX folder and copy the current file into the second device (in the same place you found the original on the first one)
It will then be transferred
