Summary: It rarely makes mistakes, and it adjusts well to changes. I will never be without one again. Sometime it is a little slow responding after a quick turn, probably due to satellite connection at the time. Other than that, it usually gives warnings with adequate time to prepare for a turn.
Summary: I love it. This is my first 7' GPS . It run pretty fast. I don't have a problem of it. It so clear and big. Can't believe until you get one of those. It also let me put addition location as one. So I don't have to type it in every each location.
Summary: actually this is the first GPS I've ever owned. so compared to reading maps to find my way this GPS was fantastic. I purchased one with a large screen so I didn't have to squint. my first use of this device was amazing.
Summary: I give this 5 stars because it worked great on a recent trip from Arizona to Texas, and back. It's not because this unit is any better than another. In fact this is my first GPS so I have nothing to compare it to.
