Summary: I was very dissatisfied with my purchase. It would not stay on new settings that was programmed it kept defaulting to another state I assume the previous owner had programmed into it. Although this was a refurbished system, it was not in the shape as advertised when I received it.
Summary: Easy to understand instructions; includes windshield mount bracket. Data entry is a snap. Good voice and visual guides. Note: does not include an ac adapter which might be a problem if run alot on battery power.
