R T Scanlon has produced a well written, beautifully structured and presented book that builds momentum, combines ideas and develops themes to a point where the satnav concept itself is reappraised. Suggestions are made to improve on how current satnavs work based on a re-examination of driver needs. This is no technical manual, instead it's a journey of discovery that allows you to avoid common pitfalls and unleash the potential of your satnav. . CLICK HERE TO START DOWNLOAD
