it is the 2nd time this happend, i'm on the road an i want to sync a route from garmin connect to my edge 830, i take the phone send the route to the device but it wont sync....
forgetting the phone and garmin, resyncing nothing happens.
when i get home frustrated i upload my ride and 5 sec later it says download complete.
suddenly the route is on the device.
it seems when you are busy with an activity the garmin wont sync as soon as it stops it syncs.
i even tried it at home with both wifi of on the phone and garmin and still worked (tought it was a 4g problem)
