good to see we got a dedicated thread for this great device. does everyone else is experiencing the auto turning off of the bluetooth after 1.5 - 2 hours? i have a garmin speedmeter on my bike with bluetooth and it displays the notifications of the phone which is really handy on a long ride. but after an approx. 2 hours the garmin says bluetooth has disconnected and when i check the phone bt is off. it happened many times so it cant be an accident/incident/whatever. anyone knows about this? it is a feature? can be disabled?
