@Android-Lolipop said in Firmware missing function-HR alerts/map data/custom batery modes:
During navigation, having the map show how many kilometers I still have to go is pretty much useless. It would be much better if I could turn that off or, ideally, replace it with something more useful like heart rate, speed, or pace.
AFAIK it is not possible to display HR on map but you can create custom sport mode with multiple screens. These screens are customizable, you can add heart rate, average HR, pace, speed, average speed and a lot of other metrics. Yes, you will need to switch between map and screens but it is just one button click.
