Will this work on an aftermarket “Pioneer AVIC-X9310BT? I purchased my car with this radio already installed. I just put a battery in my car and now it’s asking for a password. I bought the car from the dealership I work at... needless to say... I can’t get a hold of the original owner. The number listed on his trade in paperwork is no longer working... and he isn’t answering my emails.
