The installation was fairly straightforward. The front cover of the dash from the instrument panel to the glove box unclips. The difficult part is unplugging all the electrical connectors. Then I used a Ford stereo adapter and connected the wires. The Pioneer unit has an extra wire for a vehicle speed sensor (VSS) input. This can improve the accuracy of the nav system. But I couldn't easily find which wire to tap into, so I left it disconnected.
The stereo came with a microphone for hands-free phone use, and I mounted that on top of the steering column. I mounted the GPS antenna on the front right corner of the dash.
I connected the existing HDMI and USB plugs on the dash to the stereo, and I added a USB input and an AUX input in the empty hole between the two 12v power plugs. So now I have 2 USB inputs -- one supports Apple CarPlay from my iPhone. The other will support Android Auto, or can just be used as an iPod input/charger.
The AUX input will allow me to connect a cable from the TV to the stereo so I can play the TV sound through the stereo. The TV speakers fire downward into the bunk and aren't very loud anyway, so they are difficult to hear, especially if the A/C is on.
