Setup and Installation
Installation typically involves connecting the adapter to the vehicle's factory stereo CD changer port. Professional installation is recommended if you are unfamiliar with car audio system wiring.
- Prepare the Vehicle: Turn off the vehicle's ignition and disconnect the negative terminal of the car battery to prevent electrical shorts.
