1. Check the glove compartment: Open the glove compartment fully and look thoroughly. The changer might be mounted to the side or bottom.
2. Check the owner's manual: If you still have the original owner's manual, it should specify the location of the CD changer.
3. Look in the rear cargo area: If you can't find it in the glove box, take a careful look in the rear cargo area, especially under the floor or in side panels.
If you can't find it in either location, it's possible the vehicle never had a factory-installed CD changer.
