I have the same but I think it sucks. So weird that it requires hard wire for update. I understand why though, their programming sucks. I lose connectivity all the time with it, update or not. Regardless of how wifi is set up. It's the only device that I have that is finicky.
Of course, if you have a problem, apex is readily available by phone--right. I have not called in like a year but they never answered when I tried. And email with them is an arduous process. I find it amazing that they have the market.
