I have owned this GPS for 2 months. It has been used less than an hour. Today it will not start properly. When turned on it appears to load the opening pages ,"agree" and main page then goes to a white screen and then the whole process starts again over and over on its own. I attempted to use the house current with the included adaptor, my computer connection and even the 12v connection in my vehicle. Same problem each time. I have owned a number of Garmins and had no problems. Musicman
