The previous owner wrote down the radio code 31756. However when I try to enter it I only have the option of 4 numbers? I have tried 3175 & 1756 but neither worked. I am guessing at what buttons/numbers to push. Can anyone tell me exactly how you enter the radio code? Should car be running? Is there an enter button for when I am done with the numbers? Any help is much appreciated as it has been 2 months without music in my car and driving me nuts !!

 

really where do i find the answers do i need a code for that ?
