On the G300 buzzer that was no longer up to standard, I switched to 700 Wikango. I especially autonomy of GPS (almost 800 km and 8 hours without weakness, may be more .. but I preferred charge the battery for the return journey!) the display of the vehicle speed (closer to reality than that of the conventional meter) and blue and red lights (to better control the speed compared to warnings). We thus always keeps an eye on the road! The only criticism concerns the danger areas: some cabins oversights and signaling cabins attendance as they no longer exist (work on 10). A control after the next update ... but I have doubts! Nevertheless, it is a tremendous help!
