A:Answer The XAV-AX210 has three camera inputs, all have a "phono" type connector and accept composite video, it is not likely that your car uses the same connector for the camera, so you will need a wiring harness from Metra, Scosche, or iDatalink. You can check their websites for specific info on your car, or ask the installers at Best Buy. The same is true of the steering wheel buttons, the stereo has an input for them, and you can program the radio for what each button does, but you will need the proper connector and possibly a sw controller box from one of those sources..
