A:AnswerYes, you’ll need a mounting kit. Wiring adaptors make installation quick and easy, but they are never required. You can always cut the factory plug off the car and manually wire it. I don’t recommend it but it can be done.
A:AnswerYes, but with an adapter that varies with your car. I used a Maestro iDatalink RR Interface unit in my 2007 Civic Si. There are cheaper options than this to get your steering wheel controls to work, but this also made for an easier install that didn't involve splicing any factory harness wires.
Steering wheel controls worked perfect with this.
