X1 12.74 owned since last spring.
i have had no problems until recently. My runs show exactly what showed on my fr 965.  I use 1 screen - time, distance, and pace. I often run while listening to audiobooks on my iPhone. 
a few days ago the screen starts going wacky while I run. At times the audiobook I am reading shows up - full screen. I could stop and restart the book if I wanted. This never happened before. Other times the screen sows just the map without me doing anything. I can get back to the screen I want but it does stay on that screen. Other times my gps coordinates fill the entire screen. I can get rid of that. Sometimes a series of 4 or 5 beeps happens. I get lost in the screens.
when I finish I can still stop the run and the option to save the run appears. The result seems accurate.
but how can I get the x1 to just show the 1 screen I want while running, which is the only screen I did see until a few days ago.’
i restarted the phone a few times. I reset the x1 a couple of times - neither without success.
can anyone offer help/
