Just upgraded from 520+ to the 840 & like the touchscreen version a lot. I also have an Ion 200 RT light connected to the 840. The light starts up fine when I begin a ride, but doesn’t turn OFF when I’m stopped or paused in my ride. I’d like to have an option to have the light tied in with the Auto Pause function on the 840. That way, the light is not ON when I’m going less than the 3 mph I have set. I often pause my ride at a park for a 5-10 minutes before restarting my ride & don’t want the light ON while I’m stopped. An alternative is the have the light turn OFF when I’m stopped for a set time (ie 10 seconds).
