Title: Can't see the screen during bright sunlight
Review: I bought the 700 and installed it. When I plugged it in, the light on the plug-in device didn't come on. Tried it in my car and one other....I then started to drive out on the road during a sunny day and couldn't see the screen. I had to pull under an interstate highway overpass to read the screen in the shade. This may work well in clouds or the dark, but not well at all in the sun. Sent it back next day.
Is the review positive or negative?
