First of all THANK YOU I was not about to pay pioneer 80$ plus uninstallation/reinstallation fees for a 5 min fix not to mention shipping it all the way to california. I would like to add to this that when I did txtdump it didnt show me my password only my password hint ughh but after a little searching around i did find that it is also accessible in the binary dump the first line all the way to the right should be the password you set up ( minus all the . . .) in case that helps anyone else! 

is there any way you can do a video and show to me. Sorry im really confused can't really find it.
