I have a 2003 F150 Super Crew. I plan on changing the stock single CD player for a 6 CD Changer. I read somewhere that some vehicles have a "Code Protected Radios". Is this true? Will it work without a code? Will it fit with the wiring already in the truck? Also I have the Premium Sound. Any help would be appreciated. Thanks Jerry

 

there is no code on that radio or any ford from 1995 to 2005
go ahead and replace it also make sure the radio you buy comes with 2 or 3 black square plugs
good luck
