I have a pioneer DEH-P4100 and I want to remove it so I can connect the aux/ CD changer port to my Ipod. I had the unit installed at the place I bought it, but that was around 4 years ago, and it seems they took the tools that came in the box. The instructions in the manual says to insert the "release pin" into a hole at the bottom of the frame, and pulling on that will remove the frame. Then using the "extration keys" slide them down each side of the unit and then use them as handles to pull it out. I don't have the pin or extration keys so I'm not quite sure if I can remove this myself or not. I was wondering if anyone knows of a place I could order a set of new tools, or if there is another way of taking my unit out without them. Also my car is a 94 nissan pathfinder if that matters. Thanks.
