How Accurate is a GPS System?
Car GPS units are larger and heavier than handhelds, and they aren’t known for long battery life. However, all aftermarket auto GPS units are somewhat portable, with some marketed as crossover devices. Car GPS systems range from a simple dash-mount GPS navigation system to multi-component in-dash car audio system with all the bells and whistles.
GPS systems vary in accuracy according to quality, with most of today’s hand held models accurate to within thirty feet.
