i recently purchased this vehicle and the seller informed me that he had lost the code for the radio...i called customer serv. and they told me that becuase its an older model..that i would have to pay about $90 at a local dealer. they said the dealer would retrieve the code for me...however, i removed the radio and looked on the back for the serial number...its a digit number...could this be the code to put in? please help thanks guys because a girl NEEDS her tunes also, im asking this becuase i want to avoid the $90 dealership fee...couldnt i just try the serial number on the back myself?
