Said to be the best touring aid ever invented and to have already saved several marriages! The device is a simple double odometer that is resettable in small increments. Both odometers run constantly and display the distance the vehicle has moved. In touring, one can be left alone for a day or part of the tour or the entire tour to record the mileage. The other can be used with the tour directions. If a small error accumulates between the true distance and the boor tour, it can be corrected on the device so the mileage matched the tour book. I a turn is missed or short cut taken, the mileage can be reset to match the book at any later point. Control is by touch screen. Each odometer has a + and - and a reset 'button'. Simple! and – and a reset ‘button’. Simple! The device uses Satellite navigation to determine the distance the unit is moved, very much like a conventional map based device – without the map. It tells you distance with two separate and independent odometers and your speed. The device is powered by 5 volts either from a USB converter in a 12 volt outlet supplied, or from a separate 5 volt battery (available separately) or other power source. It requires a USB cord with a USB A plug on one end and a USB B plug on the other (supplied). It comes complete with the windscreen mount suction cup shown. ts loss of most or all satellites and doesn’t function.These units have been affected by the ignition (presumably) on some cars. They have intermittently lost their ability to ‘see’ the satellites and consequently cease to work. The cure may be as simple as replacing either only the coil wire with a carbon wire or replacing all the ignition wires with carbon wires, or add other ignition noise suppression. We really don’t understand the problem as it’s hard to duplicate and doesn’t happen on some cars, no matter what the ignition system or wire type. Because of their inherent value in touring we wanted to make the units available even with this known bug. In any event, if you find the device to be unsatisfactory, you may return it for full credit, less freight.
