On occasion, I find the touch screen won't respond for a period of time while on a ride. It won't swipe between data/map screens, zoom buttons don't work, can't pan, and can't bring up the home screen frame. If I wait, perhaps for 20 seconds, it'll start working again.
Ver 9.29, recording HR, Cadence, and Speed sensors. Not navigating. Map displayed. ClimbPro off.
