Just got a 2.5 Factor-e a week or so ago and have been fighting EM Connect connectivity issues ever since. I've got 3 hrs on the bike and 3 km. 2.8 hrs on the bike has been rebooting phones, bluetooth, bike, etc. Mixed results so far, but I THINK the best fix if faced w/ failure to connect is to cycle the phone bluetooth off/on, even w/ the app remaining running. Once connected, it is wonderful to be able to manage power characteristics. I'm unable to change to speedo/odo from km to miles tho.....
