Pros: Nice big screen, great resolution. Syncs up with the satellites fairly quickly. Does a fine job navigating.Annoyance: bright orange warnings pop up along the top of the display for things up ahead, like a railroad crossing, or deer crossing, or S-curve, or a speed limit reduction. There's always something ahead, so it's very distracting. This ""feature"" cannot be disabled.Major con: When it gets hot, it takes on a life of its own, changing the display to show various other screens. It's almost as if an invisible finger is poking at the screen at random times. Sometimes it very persistent, so I have to turn it off and take it off the windshield mount so it can cool down. This is a big problem in the summer, when guess what? it tends to get hot in the sun.
