I had posted this up in the "old" site and thought it would be worthwhile to repost here. Basically this is to list the steps to add a new HU to a 2010 and retain the Sync function - well almost all of it. First off I replaced just about everything for sound. New HU, speakers, sub, amps, wiring, sound proofing etc. This portion shows the fun of the new PAC wiring harness for 2010 models retaining the Sync function.
After installing front components, rear speakers, amp and sub I decided it was time to complete the package with a new double DIN HU. I wanted to keep Sync functionality with the USB and Aux plugs on the bottom, keep my steering wheel functions and not cut any factory wires. I searched high and low before calling crutchfield and finding a brand new PAC harness specifically designed for 2009/2010 Ford Sync wiring. This maintains everything and works with base and premium factory units.
The new HU is Pioneer AVH-P3200BT. I chose this because of a couple reasons. One the price was decent. I wanted a Double DIN unit that has BT, USB and Sirius ready. I don't use navigation although I can add it later if wanted. I needed a HU that had dual RCA inputs to keep the Sync functions using the harness. The other reason I chose the HU is that if/when Sync runs out, I still have BT, USB and Sirius and be able to keep my steering wheel controls.
The other reasons for the HU choice is that it has 3 pre-amp RCA outs. Front, Rear and sub.
Onto the goodies. I got the Metra bezel in the factory silver color. This thing is a perfect match. Got the PAC-SWI for the connection for the steering wheel controls. Got the Sirius tuner and Pioneer/Sirius connector to plug in the Sirius.

Here is what it looks like all spread out:
After figuring out the wiring and butting the HU harness and goodies it was installation time.
HU in new bezel:
I connected all of the PAC harness wiring to the Pioneer harness, added the relay for the parking brake, plugged in the PAC SWI, and got everything in order. The harness comes with another relay for a toggle between AV/DVD and auxiliary. So all of that stuff needed to go inside of the center stack. For ground I used the stock PAC harness ground which plugs to pin # 13 for chassis ground. The HU was plugged into that. I also grounded the HU chassis using the screw mount in the back of the HU. That was run directly to the dashboard chassis. I also ran another ground for the relay for the parking brake. That too went to the dashboard chassis.
Up next was testing the connections. The SWI programmed easily and all of my steering wheel buttons work. The great thing about the harness is that you do not need to add in a 100ohm resistor. Just plug in, program and go. After confirming that everything powered up and was working, I had to fish up the sub and front RCA, remote and BT microphone from below. I placed the main PAC harness directly under the dash bar as it was really the only place I could. Used leftover double sided sticky Velcro from the soundproofing project. Then the PAC SWI and one relay velcro’d to that. It made for a nice easy spot to mount out of the way. I tied back the mess and cleaned it up a little before installing the HU in.
The verdict. Everything powers up perfectly. RAP feature is still in tact. Sync does work but there is no factory voice – no Sync lady??. When I press the Sync button on the wheel, the dash up top does work just like it used to, except no voice. I can say “USB” and it goes right to the USB and starts playing. For the sound to actually work, just switch to AV on the HU and there is the sound. So Sync works, just no voice. My voice commands Sync just like it used to. As long as you say the right commands, it works.
I can play audio just fine but there is no Sync voice. Also my BT through Sync does not work (which I figured) so I am glad I got a built-in BT model HU. A quick disconnect from Sync and connect to the new HU makes it just the same. At least I have everything I wanted. The HU is great with tons of great features like EQ, sub settings, HP/LP filters, etc. Plus it just sounds amazing.
Wiring the mess:
In place before tying it up:
Finished product. Note the top display of running USB from the factory plug.
After having this in for a couple of months now, I don't even use Sync any more. If you want to retain Sync, then this may be one of only 2 options out there. Metra makes a kit for this as well but the SWI-PS needs to be wired in with a resistor. The PAC version plugs directly with the SWI-PS and no splicing/soldering is needed.
Everything said and done with deadening, 2 amps, etc. the vehicle is amazing...
