Have used 830 for about two months with no problems. Am running SV 5.10 About 80 miles into a ride this past Sunday, the 830 suddenly dropped connection to my Stages PM and my HRM. Recorded the rest of the ride without problem. However, after pressing the Stop button upon completion of the ride, the 830 froze completely. Had to do a hard reboot to be able to save and upload the ride. On my next ride, no problems so I sort forgot abt the Sunday mishap. Today, the 830 locked up 27 miles into a 50 mile ride. Did a hard reboot when arriving at home. Could save the 27 mile part of the ride but the remaining 23 miles are lost. Irritating. Is this a warranty issue? The 830 has turned completely unreliable. Seems that it may be necessary to run a second device as backup. This is rather ridiculous. Is Garmin actively working to fix this problem given that it seems to be an issue for many 830 users?
