Mine came with a paper manual, but I find it usually not that helpful. More helpful has been the user forums on Motion Based (I'm not sure if that is the same name these days). The first time mine would not turn back on after charging, I freaked out. No mention of how to reset from Garmin, but I got the answer quickly from checking the user forum (push in the mode, lap, and power buttons at the same time). I wish the "GPS off" setting was a little easier to get to...
