I can connect to wifi but when trying to update i get a error message unable to connect to server. Have tried multiple wifi but same message. Registered my device online and tried to update via USB but just get a frozen blue screen on device saying update mode. I can read the sensors on teh vehicle, Toyota Tundra but cant figure out how to register them to the vehicle. Each time i try i get a message must register device and had 10 free attempts before having to register which are down to 1 attempt left. Extremely frustrating to use and no instructions.
