My 02 doesn't have the CD changer function but it does have the tape function, will the PIE-AUX adaptor work with my car?

Also I am concerned about the code for the headunit when I disconnect the battery, I purchased this car used so call I just call up a dealer for the battery code? Is there a charge for this?

 

nm...installed and working great!

 

I think you'll find your 02 HU has the ability to control a changer, but without a changer attached it doesn't appear as an option. As soon as you plug in the PIE AUX adaptor it becomes available.
