Does anyone know why an aftermarket stereo with CarPlay would have caused my key fobs not to work.
Both key fobs used to work fine when I first got the car. 2 weeks later I then had the stereo upgrade from a local audio systems service center.
It's been about six months since my 2009 convertible gt 4.6l V8 45th anniversary key fobs has worked.
Sometimes I notice my subs going in and out and there are no shorts or loss of power because I checked all but rca jack wires (behind the stereo)...

Key Fob not working on 2009 gt 45th anniversary since i had stereo upgrade with a lows amplifier and Subwoofers and same shaker 500 door speakers
