I should have also posted for the original poster that I have my original radio, the same as he has, if he wants to replace it.

It also has the PIE Ford AUX adapter that plugs into the remote CD Changer port (unused on these F-series installs) that provides a standard AUX input. I just plugged an 1/8th inch audio cable into it and ran it out from under the dash for easy access to plug in things like Sirius/XM radios, MP3 /iPod players, etc.

My primary reason for upgrading to a new radio was that I wanted something that supported a subwoofer, which I've installed under the rear seat.
