My Zumo 550 died on the way to Lamont's to get aligned. I stopped and when I restarted the Spyder, the unit just would not power on. It also would not power on when disconnected from the Spyder. I called Garmin and they had me remove the battery pack, and then connect it to the computer with the USB cable. When the unit powered on, without a battery pack, it established that the battery was just dead. After 7 years I am not surprised. A new battery fixes the unit! :clap:I thought I'd pass this along because it could also be true for the Zumo 660 and others. FYI
