I am selling a Steering Wheel Control Adapter that fits Mazda2, Mazda3, Mazda5, Mazda6, CX-5, CX-7, CX-9, MX-5, Miata, RX-8. If you want to install aftermarket stereo in your Mazda, but want to keep the functionality of the steering wheel buttons, you need this adapter. Please check to make sure the adapter fits your car. You can use crutchfield or any other car audio site to do that. Feel free to call/text me with questions you have!
