I jus bought a Creative Mp3 player...I want to hook the player in to the factory radio...my radio is the single cass and disc...not XM, Onstar or disc changer..has anyone hooked a mp3 player to theirs...I dont have the aux button...I have been researching different aux input devices..but I get so confused...there are so many...so I figured if someone has the same truck setup and they might have did the same thing...jus not sure which one to use...thanks for any help..and sorry for rambling...
