Vehicle owners who have a Clarion aftermarket head unit installed into the vehicle's stereo mounting dock may find the need to remove the deck from the vehicle's dash. Connecting external car audio devices, replacing and repairing the unit will first require that you remove it from the stereo dock. You can choose to have the removal handled by a professional car audio mechanic, or you can do it yourself and save money.
Lift the vehicle's bonnet to gain access to the battery cables. Loosen the bolt on the negative battery cable clamp with the wrench. Remove the cable from the negative battery terminal. Set the cable aside and move to the inside of the vehicle.
Remove the dashboard panels that conceal the Clarion head unit within the stereo bracket. Follow the instruction in the repair manual for your specific vehicle.
Slide the Clarion until from the aftermarket stereo installation sleeve. Disconnect the stereo wiring connected to the left side of the unit's rear panel. Unplug the antenna cable lead from the lower-right corner of the Clarion's rear panel.
