Installing the DAB+A device into the car is simple: you place the DAB antenna (windshield mount antenna, rooftop antenna, antenna splitter), and add power to it if it's an active antenna. Then you connect it to the DAB device, and the DAB device needs to be plugged into the AUX input of the car, or if the car has no AUX then the FM mode will be used insted. We have a video about the installation and from the first time use: https://www.youtube.com/watch?v=BNJqyCVNllM
