Simple, versatile accessory that is the future of GPS speed signal converters. GPS speed signal converter offers a 66 satellite connection which captures the satellite signal; the converter then transfers it into a pulse signal that communicates with the speedometer. Sleek, wireless look provides a perfect alternate to conventional speed sensors that are installed on the wheel. Converter has an internal memory of 20 km, so there no need for concern when entering a tunnel or if signal is lost.
