You do not need a code as the stereo does not require one.
I've been looking for a central resource for the Scion head units with no success.
After hours of searching on 4Runner and other Toyota forums, I've created a master list of all the head units (at least the ones I could find information on) and their capabilities. I'n sure I'm still missing information about each head unit, so feel free to post any udpates you know about and I'll be happy add them to the list.
I'd like to eventually get pics of each of the units as well (front and back), so if you have a particular unit, send me the image link and I'll post it as well.

I just did the T1819 install in my 2008; it went in like butter thanks to the info on this thread! Didn't do the USB cable, but BT phone and audio work great, dimmer, steering wheel controls, HD radio with good reception, armrest aux input, and it definitely sounds better than the stock radio.
If anyone's doing 4th gen T1819, like people here say you need at least those three cables listed:
28 pin harness- PT546-00120-CH
Antenna Adapter- PT546-00120-AD
Bluetooth- PT546-74120-MC
For Bluetooth and basic operation.
Add these antenna adapters, if you don't have them from elsewhere:
Amazon.com: Metra 40-GM12 GM Antenna Adapter (Barbless): Car Electronics
Amazon.com: Metra 40-UV43 Male to Female Motorola Antenna Cable: Car Electronics
Not a wire was cut, no tweaking anything, just plug it all together, fire it up, and find the pairing menu.
Thanks again all.
I'm wanting to go this route, but can't find if it's compatible with the JBL Synthesizer? If not directly, is there a converter I can add?
thanks for posting this, really appreciate it!The install was fairly straightforward once I figured out I needed the "reverse" harness shown above. You have to solder the reverse wiring harness to the Metra converter, but it's just matching colors:

Other than that, you'll also have to deal with the poor fitment with the bezel, if that bothers you. The JBL head units are a different shape than the normal ones, so the Scion head units don't fill up the bezel quite as well. You'll either need to source a non-JBL bezel or make an adapter ring.

thanks for posting this, really appreciate it!
worth noting on the fitment, do you have a limited? i have an '05 SR5 that has the upgraded JBL option. I believe that these scion units will fit directly in trucks that are not limiteds, but have the JBL option.
referencing this thread (http://www.toyota-4runner.org/4th-gen-t4rs/123639-jbl-head-unit-versus-all-others.html#post1161861) i have the picture on the top, where as I would assume you have the picture on the bottom. i believe this is the reason for the slight misfitment.
