Interface for hands from steering wheel Renault with or without a screen in the dashboard. This device allows us to activate the controls on the steering wheel if we have changed our original radio on the other. Very useful when we for example a browser other than the original and we are left without the function controls on the steering wheel. Only valid when the car ALREADY has steering wheel controls but when you put a new radio we have lost this function. With this interface we get the function controls on the steering wheel. Compatible with all brands of radios on the market. Download the APP AUTOLEADS CONTROLPRO and look at the compatibility of your vehicle with these interface. You choose: brand, model, and brand of radio. If there is no your model is that it is not compatible. Once you find the interface, click on the image and it will tell you the installation steps (very simple).
