Can somebody explain please what the 'Timer Overlay' option on the 1030 is supposed to do please ?
When I tap on the screen during a ride I get a screen overlaid over the top of the current screen(s), but it shows nothing except for the temperature and the time of day right at the top and then nothing else, the majority of the overlaid screen being blank.
What is it supposed to show me ?
Much vagueness in the instruction manual.
