Garmin 820 edge , trying to install street map of Mallorca

A REAL green bean here ! Looking for a brainiac to step by step show me how to find and install a street map of Mallorca on my Garmin 820. Garmin 820 has a internal storage of 16GB and I don’t want to delete my street map that is on there now. (9 GB used)


Go to and download Baleares.
When not enough place on your device (I doubt) temporarily back up your device map on your pc.

Thank you Martin !
