For many years, people have been asking and requesting to be able to effectively use all the buttons of this not at all cheap device. Is it really such a big problem for you to enable own configuration of the "Lap" button ? It seems to you that we all do nothing else but ride track cycling and have to count our laps ? This may come as a surprise to you, but track cycling athletes do not use this type of device at all - and yet for 3 buttons you "wasted" one for a function that probably 5% of the owners of this device use.
I've had enough of another fill-in-the-blank idea on www.garmin.com/.../ - you probably don't even read them.
I'm calling out Garmin_Matthew - please push this topic further to people who can do something about it.
