Unfortunately, the off-road information was often lacking in detail and accuracy. These maps were designed in such a way as to allow the GPS device to navigate using stored digital roads, including some off-road tracks, to get from point A to point B without the need to refer to paper maps. GPS technology developed quite rapidly with the introduction of commercial digital mapping that could be incorporated into portable GPS units. The issue with the GPS-45 and other early consumer GPS units at the time was that you still required paper maps to relate back to the information the GPS provided. If you did any off-road travel, it provided unparalleled peace of mind. Not only could you determine your position within seconds of turning it on, but you could program waypoints into it, navigate to those points and, if you found yourself lost, you could retrace your tracks using the ‘breadcrumbs’ feature. It was a Garmin GPS 45 and back in 1995, it was a staggering piece of technology. I remember when I purchased my first handheld GPS device.
