I am looking at purchasing a hand held GPS with the biggest screen possible. Does anybody know how fast the navigation is updated? I will be traveling up to 125 mph and need accurate updates on location. Not real picky on the brand or cost as long as it is fast enough.
You ever ask a question and regret it? Went to an aviation forum to ask and I get 3 pages of geeks telling me what I need, not one had an example of an aviation gps that showed roads. I will be giving address and directions to engines that drive on roads that is the information I need.
