SWC is the Steering Wheel Controls. The stalks near the steering wheel adjust the volume, skip a track forward, backward and pause.
SWC comes in two distinct formats: factory fitted by the vehicle manufacturer or aftermarket universal fitted.
Factory fitted SWC
Factory-fitted SWC needs an interface adaptor to connect to an Android headunit. Typically, a CAN bus adaptor is supplied with a custom-fit Android headunit tailored specifically to that vehicle model. This is ideal because installing the custom-fit Android headunit and the supplied CAN bus adaptor keeps the factory-fitted SWC functioning.
Universal-fitting Android headunits can connect to factory-fitted SWC using an appropriate Connects2 style adaptor. There is no CAN BUS box for the universal headunit. So the additional adaptor is tailored to your vehicle electronics and interfaces these to the Android headunit.
Aftermarket SWC
Suppose your vehicle is not fitted with SWC, and you install a universal fit (like the very popular pumpkin). In that case, adding an aftermarket SWC directly to it is possible. Many different aftermarket SWCs are compatible with a universal Android headunit, but we have picked our favorite here. It has a sturdy mounting to the cowling and feels well made. Connection is simple, with only three wires to the headunits KEY1, KEY2, and GND wires.
Mounting the recommended SWC
Use the supplied screws that self-tap into the plastic cowling when you are sure the position is correct. The supplied sticky pad is just for temporary placement and testing to ensure the correct position before installing the screws.
