Today, I would like to tell you how to connect the steering wheel control to Joying android car autoradio.
Please confirm your car ( such as VW, Opel, Ford ) has canbus or not and if it supports canbus. If so , you will have to connect canbus decorder. For VW, the steering wheel control will work and you don't need to set steering wheel buttons. Because Joying VW car stereo steering wheel buttons is fixed, but you just can use four buttons control by Joying VW head unit. other four buttons is used to control your original car center dash. The VW steering wheel buttons can not be changed.
If you want to purchase double din, and your car is toyota, Nissanand ,VW or other car brand which can't support canbus, you will have to learn and set the steering wheel buttons. You need to find your original steering wheel wire, then connect our head unit steering wheel wire Key1 or Key2. Pleases note that the GND(groud)wire must be connected.
Please kindly check two videos below to learn and set the steering wheel buttons.
