I took my radio out to switch cars and when I installed it on my new car it's now asking for a password and obliviously I don't know it, I do not wanna send it in to pioneer to pay for something that I should be able to get by myself on my own radio, does anybody know how to either get by this password or get it to factory original settings so I can use my radio again, again I have the model 6100 nex, PLEASE someone help, I'd appreciate it so so much, thank you
