Vehicles that are equipped with double-DIN stereo decks often have multiple components included into one unit, such as a CD player and cassette deck, or a CD player and navigation system. Car owners can choose to replace their double-DIN factory stereo unit with a slimmer single-DIN model. You can choose to have the stereos swapped by a professional car audio technician or you can do it yourself and save money.
Disconnect the grounding cable from the vehicle's battery. Lift the bonnet to loosen the bolt on the cable with the wrench. Lift the cable from the battery and place it to the side of the battery. Move to the inside of the vehicle.
Remove the stereo, following the instructions in the repair (or shop) manual. Disconnect the wiring connections to the back outlets of the stereo (antenna and stereo wiring).
Connect the wiring harness adaptor to the vehicle's stereo wiring to match the outlets on the new stereo deck to the vehicle's stereo wiring.
Insert the single-DIN stereo faceplate adaptor into the stereo dock with the storage pocket below the stereo dock opening. Pull the wiring harness through the faceplate adaptor. Plug the wiring harness leads into the outlets on the rear panel of the single-DIN unit. Insert the antenna cable into the antenna outlet on the back of the new stereo.
Slide the single-DIN unit into the upper opening of the faceplate adaptor until it locks into place. Replace the dashboard panelling as instructed by the shop manual. Return to the battery.
Place the negative battery cable back onto the battery and tighten the cable's clamp. Close the bonnet.
