Radio Removal Tools: – Dash Removal Plastic Pry Tools – Open the center console lid and remove 2 7mm screws that hold the gear shift/cup holder panel in. Then pop that panel unplug any electrical connectors and remove it. Now starting at the top using the tools above pop the entire radio / climate control bezel off. There are no screws holding that panel on. Set the ebrake as you’ll probably have to put the shifter in a lower gear to remove that panel. Carefully unplug the airbag connector at the top and you can set that panel to the side of the console or unplug all the connectors and completely remove it. The radio is then held in with (4) 7mm screws.
Keep in mind if you are installing a new radio in your Explorer you need the wiring harness, the antenna adapter, and the mounting kit as well.
