Carsifi set-up is a very easy process. First time when you connect Carsifi to your car you should complete Bluetooth pairing. To do that, please open your Android Device Settings -> Bluetooth and click the "Pair New Device" button. After that, your Android will start searching for new devices and you should select a device named "Carsifi-xxxx" (xxxx is the number of the device which is different on every adapter). In just a few seconds you will be enjoying wireless Android Auto. You only have to set it up once for each device you want to connect to your car. After that, Carsifi will detect your Android smartphone and reconnect it automatically.
