Introduction While "All-in-One" GPS navigation systems by Garmin, Magellan, Navman, Cobra, Lowrance or TomTom have been making a large dent in the GPS market over the past year, "Do It Yourself" GPS assisted navigation remains the most flexible way to navigate, as you can choose your software (road/all-terrain), hardware (PDA, VGA PDA, Laptop) and change the components as new and more powerful options become available.
