What procedure should I take into putting a new radio into my ford explorer?

Most aftermarket radios will require a install or fitment kit. If you have a newer Explorer then it might not have a single or double DIN standard sized stock radio, often on new cars you need to get an aftermarket dash/center stack bezel, and if you have radio controls on the steering wheel you might need an adapter for that tool.

These are things that you should already know if you're attempting to install a new head unit in a newer car. It's not hard if you have the correct wiring harness(es) and you know what you're doing, however you might want to just pay an audio shop to do it.
