Things You'll Need
Socket driver or ratchet
Ford DIN removal keys (for Ford, Lincoln or Mercury vehicles)
Double-DIN stereo decks are twice as tall as standard single DIN stereo units and commonly more capable. Car owners who wish to add aftermarket external components such as satellite radio receivers and GPS navigation systems, will need to connect the devices to the outlets on the rear panel of the stereo. You can choose to have the double-DIN deck removed professionally or do it yourself and save the cost of labor.
Lift the vehicle's hood to access the battery. Loosen the bolt at the end of the negative battery cable with a wrench. Lift the cable from the battery terminal and set it aside. Move to the vehicle's interior.
Remove the dash panels concealing the vehicle's stereo mounting dock. Consult the vehicle repair manual for specific instructions for your vehicle.
Remove the screws or bolts surrounding the stereo bracket with a socket and drive or screwdriver (depending on the vehicle make and model). Slide the stereo from the dock to access the wiring connections at the rear of the unit. For Ford, Mercury or Lincoln vehicle: insert the Ford DIN removal keys into the holes at either side of the double-DIN stereo's face. Push the tools into the unit until they lock into place. Pull outward on the tools while sliding the stereo from the dock.
Disconnect the two stereo wiring connections on the right side of the stereo unit's rear panel. Unplug the antenna cable lead from the FM antenna input on the opposite side of the deck's rear panel.
