KHirsch replied to RonS's topic in Hacks/ModsWow.. I was lucky to find this. Couldn't find anything like this anywhere else online and was stuck after my battery became disconnected on my truck and recently bought it used with the aftermarket unit installed. I wasted a lot of time trying possible passwords and calling Pioneer who wanted to charge $80 just to send it back and take the password off. You have helped a lot of people!! THANK YOU!
