Query: First days of the Roadmate 700

Day 2 of having the Roadmate 700, and unfortnately, I got a bad one. After 15 minutes of having great coverage, the power goes out. It will not stay on, until it cools down for an hour or two.I really believe in this product since two of my friends have the same one, and love it. Hopefully number 2 will be working better, but my road trip planned for tomorrow, will be reliant on maps and compass.When it works, it's a 5 of 5 but until then it only gets two.Loren
