Garmin Edge 705

I am having trouble selecting the openstreetmap in settings. When I go ‘settings’ ‘map’ then highlight ‘openfietsmap’ and press ‘enter’ no tick happens in the box. Is the gmapsupp compatible with the Garmin Edge 705?

The original Garmin map was accidentally deleted when I was trying to clear some memory.

Thanks in advance.

Don’t worry. I found the problem. I hadn’t extracted the file correctly.
