Audio Systems: 06 f250 deck swap, input interface, ford f250

Question
I have an 06 f250 and I want to swap the stock deck for and aftermarket one. What will I need to change these myself? I have heard something about vehicle security running through the deck, is this true? If so, how does one get around that?  

Thanx for your time,
Alex

Answer
just get a radio kit and a harness  there is nothing special on the radio and nothing to do with the security system

if you are replacing the radio to plug your ipod or mp3, there is no need to do that just add a auxiliary input interface made for that factory ford f250 radio
