I just got my 520. There doesn't seem to be any memory available. I'm using a Mac and select get info on the menu for the Garmin drive. It says there is only 1.9mb available out of the roughly 110mb. I tried adding a map file, then needed to delete it and that is when I ran into this issue. There is now other new files. The size of the next Garmin folder is only roughly 55mb. Because if this, I can't add the map. In addition I can't sync Strava Segments and I also can't even sync ride data wirelessly via Bluetooth to th connect mobile app. So far, none of the special features of the 520 work. I've tried disconnecting the strava/Garmin link and even reset the 520 with no luck. I'm using the newest versions of everything too. Strava segments are showing up on the Garmin connect dashboard as well but nothing is syncing. Garmin express does recognize the 520 when it is plugged in via USB and the mobile app says it syncs via Bluetooth as well...
Any ideas? Anyone else run into this. Feel like I've tried everything at this point.
Thanks!
