I have a lot of rides in my GC, I recently bought a 1030. Its connected and everything syncs, except old rides from GC are not syncing to 1030. Is there a way to get old ride history to 1030?
The Garmin is not intended to be a storage device. It simply gathers data and the data is transferred to websites like Garmin Connect or Strava. Keeping a excessive number of rides on the Edge it not recommended. Doing this will slow down the Edge and could cause file problems.
If you still have the old Edge device you can connect it, open the Garmin/Activities folder and then copy all the files there to the same location on the new Edge. You will then have them. Put as posted above the Edge is not really the place to hold your history. It can be done however.
