Used my 550 Sunday and Monday this week without issues. Went to use it Tuesday and it would not switch on at all. Contacted Garmin Weds who advised a "master restart" comprising pressing the bottom right corner of the screen with the on / off button at the same time and holding for a time. Thus did not work and neither dud charging the unit from my desktop. My question is - is this a battery problem that a new battery would solve? Any one had this problem and have a possible solution? Is it just me or is the 550 unit inherently unreliable as I have had no end of issues with my original unit and a replacement provided by Garmin.
