Ok Question I just installed a Pioneer DMH-1500NEX with the Maestro Interface and everything is working but when trying to use Siri or when making a phone call they cant hear me. All the buttons work on the steering wheel it just seems like the Mic isn't working. The Radio came with a microphone but the car already has one. Do I need to do something different to be able to use the preexisting mic? Any help is welcomed!!!
