My 2011 CX9 main radio controls will not work. I have to do everything with the steering wheel controls. The only thing that works is the volume. I cant change presets, adjust audio settings.. nothing. They dont beep when pushed. I noticed one button appears stuck. What are my options
I'd pull the head unit and see if you can disassemble it enough to un-stick the broken button. If that doesn't work I'd head to e-bay or a junkyard and buy a used one to swap in. I'm sure the OEM part is absurdly priced through Mazda.
