Garmin 935 goes into autopause (for no apparent reason) on a bike ride and won't come out unless I power the device off and back on. It may just have lost the GPS signal. It's not like I stopped or even slowed down that much. I've gotten this on my new Edge 530 too. I've already gotten a replacement for the 935 and after a year, it is happening again on the new unit. My Garmin Edge 500 works flawlessly during the same ride.
