We bought this GPS unit from Costco a little over one year ago. A few weeks ago, the machine started giving us trouble. I checked the battery level and found it low and charged it by plugging the USB cable provided directly into my IMAC. The battery charged. I updated the map about a week ago and now the machine will restart itself without me prompting it to. It did it several times on the way to an event last Saturday and yesterday. I hope there is an easy answer to this one.
I would appreciate any answers or suggestions.
Thanks.
