So it can stay flush with the interior like this:

I did alot of reading here, scionlife, and avic411, so I did the whole installation by myself. Estimated savings is around $300.

BTW, that's an actual pics of MY headunit 

its super easy, here are the pics i found on the newscionxb, so here it goes...

1.  With both hands grab firmly the black trim around the radio...




2. PULL BACK towards you, on the trim. you should feel it pop out
3. There is another small trim piece that needs to be pulled out, it is located at the bottom of the the radio.
4. There are four 10mm bolts that hold the radio in that need to be removed.
5. Once bolts are removed, the radio should pull right out!!!

Here's a PDF on how to install the factory navigation (if you had bought it with my car)

You don't have to cut anything on the Scion to make it fit. If its already bypassed by moving the mute wire, and grounding the parking wire, you don't need to do it again.

I would just follow the PDF, and install the D3 like normal

(crutchfield bracket) -> (Metal Harness in car) -> (D3) <- (Metal Harness in car) <- (crutchfield bracket)

OK so i put in the d3 this weekend

I did not get a chance to finish.

how do i get the mode button to light up again?

there are two harnesses that were not used going from stock to d3. what am i supposed to do with those 2 harnesses?


i am still waiting to get time and install the pac ps as well
help!

instructions from pac:
http://www.pac-audio.com/swixprogramming/showstepbystep.asp?InterfaceChecked=3&RadioGroupPioneer=0&mmSearch=Scion&Submit2=%20Search%20Vehicles&ID=386

for the programming of the pac, its very straight forward, you would just skip track up/down in favor for preset up/down

for the resistor, on the white interface wire from the pac controller, you would splice in half, with 1 half connected directly to pin7 i believe, and you would solder the resistor to the other half of the white interface wire before connecting it to pin 8.

the black wire from the pac controller connects to pin 6 black wire

resistors look like this:



here are my home made "paint" instructions:



toyota steering wheel harness pin layout:

That background comes with the RS series pioneer units. You could make it in photoshop if you want or you can create your own. Simply use a SD card or usb if you have a newer avic f series unit. with the D series I believe you have to put it on a data cd.

sorry to revive a dead post.
