If you're like me you probably like the look and layout of the base 2010 radio (T1814) over the 2009 and older models. If you wanted to put the 2010 radio, however, into a 2009 or older Scion you'll find that almost everything fits, except the iPod connection. In 2010 they changed the connector on the back of the head unit from the narrow rectangular one to a more square USB looking one. So the iPod cable used on any older models cannot be used with the 2010 radio (both the base Pioneer unit or the upgraded Alpine unit). Furthermore, no one yet sells a cable that connects to the head unit for your iPod.

I've come up with a solution that will allow full functionality of either the 2010 base Pioneer or the 2010 Alpine radio to work in your 2009 or older Scion. My solution is a modification of the helpful information provided by DDStrat and Dave90T in the thread "2010 Alpine Premium 100% Working in 2008 xB" on this site. In that thread the solution will cost around $250 for the two parts, as well as a good amount of disassembly of the center console area. My solution isn't cheap either (around $105 for one part), but it still provides the same functionality, and requires a lot less messing with disassembling and reassembling of the interior.

Here's a summary of the modifications:

1) I purchased Part # 86203-12340 from Toyota for $105. This is a wire harness for the 2010 xB that goes from the new 2010 USB/Aux connector on the center console to the parking brake area.

2) I cut off the part of the harness that contains the brown connector which will connect to the back of the head unit.

3) I took an iPod cable (such as the cable you use to sync your iPod to your computer) and cut off the USB end.

4) I spliced these two pieces together. They both are essentially USB cable that contain four small wires (black and red for power, and two other colors for signals). You may have to test the colored wires both ways since they may not match in color.

5) I plugged the brown connector end of my new cable to the back of the head unit (I had to file the connector a little bit to get it to fit), and the iPod connector end to my iPod. I routed the iPod cable to the glove box.

And viola! My 2010 Scion radio works perfectly in my 2009 xB. (Note: This works for both the base Pioneer unit or the upgraded Alpine unit).

Note: If you want to keep the auxillary function it's necessary to make one other (small) modification. You'll have to redirect a small wire on the C27 connector from pin 14 to pin 18 (see the thread by Dave90T called "2010 Alpine Premium 100% Working in 2008 xB" for a diagram in post #6). Otherwise you'll have everything else working except auxillary).

Hope this helps. Also, hopefully someone will come out with a cable like the one I fabricated for a cheaper price! But until then, if you really want that nice, new radio in your 2009 or older Scion, this is probably the cheapest, and easiest way to do it.

Nice job Jerrymontano!! Doh - I didn't think of routing ipod to the glove box area when I came up with my more expensive solution for installing the 2010 Alpine premium unit in my daughter's 2008 xb2!! (see Dave90T's thread)

Thanks DDStrat! It works pretty well, although your solution keeps everything in its original place. Thanks again for your guidance. If it wasn't for you and Dave90T I wouldn't have even tried this.

Sharing a link to my post on the Toyota forum (since I installed this unit in my 1999 4Runner) that gives step by step instructions how to solder an inexpensive USB extension cable to the internal circuit board on the T1814 that will give you full functionality for USB flash drives, USB MP3 players and iPods.

Update on my cable that I fabricated in the initial post: I ended up buying an aftermarket radio so I am selling this cable on eBay for $35. Let me know if you're interested. The cable is ugly as sin but it works fine.
