So I bought my 13 premium sedan 4 days after the special order cut-off. It had everything I wanted but nav. I wanted OEM, so I decided to roll the dice and attempt the transplant. Thanks to this thread, and David's guidance and harnesses (thank you again!!), and a fully functional ebay Fujitsu Ten HU out of a 12' (pd $300- Subaru quoted me 2k), the installation was very straight forward. As this thread/ discussion enabled me to perform the install, I've tried to document everything in a useable format to hopefully fill in any gaps for any of you looking to do this, as a thank you to the community and the service it provided to me.
Below are all of the parts you'll need for the the installation, and a general how-to. And for those of you who want to use satellite radio and don't want to rip down your headliner to replace your oem antenna/ wiring (if you have a 13, your antenna does not have an xm receiver built in, nor is it pre-wired), I included the adapters you'll need in order to run any aftermarket xm antenna into the HU.
Just an FYI, the interface on the Fujitsu Ten is great, and the sound quality is much improved. The FM reception, even with the HD radio is still laughable, but I feel like that's a Subaru hallmark. My only gripe is the BT speaker phone. The only time anyone can make out what I'm saying is parked with the engine off (and yes, I have my mic volume max'd). Other than that, all steering wheel controls and functions work as-stock. All console mounted inputs (aux and USB) function correctly.

Purchased from David(SVXdc):
(1) 10+6-pin reverse harness (w/ illum.-)
(1) 20-pin forward harness (w/ illum.- & long 3 SWC)
(1) 28-pin harness assembly (w/ VSS, r.gear, SWC, 16-pin>aux/mic)
(1) 16-pin rear camera harn. (w/ p.brake bypass, 6V, Impreza loop)
(1) Subaru USB cable (to male USB A)
Purchased Separately:
(1) GPS Antenna ($12)

(1) FM Antenna Adapter ($13)

(1) Lexus reverse USB adapter ($10)
http://www.ebay.com/itm/190850462942...84.m1439.l2649
(1) OEM Subaru Nav Bezel ($72) This really isn't necessary.. Other than the corners being rounded(vs square), and the HU sitting a bit more flush (vs recessed using standard bezel) normal human beings really wouldn't be able to recognize any discernible difference. I'm advising to save your cash on this one(see pics below).

The XM was the biggest PITA for me. The proprietary square plug was impossible to adapt, but the GPS antenna's plug is remarkably close (with a tiny bit of dremel magic). So essentially, I purchased 2 of the same GPS antennas listed above, using 1 for the GPS obv. and the other to splice into the "XM antenna adapter," essentially creating a patch cord go-between to be used to mate any aftermarket XM antenna to this HU.
Here's the kit of parts after soldering and heat shrinking David's harnesses (minus the USB wiring which I received after taking this, and the XM patch cord). Note, the spool on the right.. red is to VSS, black is to reverse gear. David supplies you with color decoders and instructions for his harnesses as well, so there's no guess work involved. The nav unit I purchased didn't have the mounting brackets but the stock HU's swapped directly over.

I used 3m tape to affix the GPS ant to the top of the cluster, beneath the hood. Reception is perfect. FYI, the wrx dash pops apart easier than my childhood Camaro's. The hood is held on by 4 clips and pulls straight off, and the radio bezel with another 5 plastic clips, so don't get intimidated. I pulled the cluster out (2 screws..I know..) to route the GPS antenna wiring to the back of the HU. I also pulled the hvac duct in the stack to free some space so I had room to organize the myriad of HU harnesses(2 screws).

You'll need to tap 0-3 wires from the vehicle harness depending on what you plan on installing. An easy access point for the VSS is through the harness under the glove box. It's pink/green. I connected it at first but found it to be utterly useless and quite the nuisance so wound up disconnecting. The reverse gear wire can be accessed through the harness above the passenger side kick panel, if you're connecting a reverse cam. It's brown and yellow. You'll also need a 12v switched power lead, which will connect to the cam +. I tapped into the switched 12+ from the clock harness
*see emboldened revision/note below. This one is brown/white. If you're not doing a cam, and don't mind the GPS getting confused in tunnels, you don't have to hack into anything.

I mounted the cam in center of the trunk garnish. The honkin connectors hard wired to the cam itself were able to fit through the stock hole in the trunk (where the plate light wires exit). Just shoved the grommet through, pushed the cam wiring through next to it, and pulled the grommet back out to it's original position. This HU has to sense a cam within 5 sec of boot up or the cam function will be overridden, which means
the camera needs to be wired to the switched-on as mentioned(clock).
Correction: the camera harness David supplied has a red wire. This can be used as the switched power supply as well.
As for the XM, this was my solution:

Splice the GPS connector into the XM adapter. Viola- your patch cord. You'll need to shave a bit of extrusion on the GPS connector but it's super simple and very easy to do with a file or dremel (shown here). As I said earlier, this was..a source of stress for me. You would need to purchase approx $300 of hardware from Subaru (antenna body, mast, wiring) and drop the liner if you wanted to go stock appearance. I was unable to source a splice cord or square terminal adapter to do this any other way than to splice the 2 seemingly unrelated cables. I mounted the xm ant on my trunk, but you can place it on the rear deck under the glass (barring metallic tint on the rear window) or on the dash.
I have tons of photos covering just about every phase of the install if anyone needs specifics. Good luck.
