Guess what I did today...
Can you see it?
Look closer
What is it you say?
Handsfree Bluetooth I say!
Alright, alright, I'll get to the details. This works on any radio (newer OEM, aftermarket, Scion etc) that connects to the factory harness using the grey connectors in the OEM harness. It actually only requires the larger of the two plugs. There is no splicing/cutting/soldering involved.

I bought this from Toyota Canada (part number PZ409-0029A-B0)
The pair of connectors in the top right corner of the above picture connect inline between the larger grey plug in the stock harness and whatever you have on the other side (aftermarket harness, Scion HU etc). The single wire is a trigger wire to mute the music during a call. My headunit didn't have an input for this, but I would wager that those of you with fancier units than I would have this function. I just taped it up out of the way.
The black box near these connectors attaches to the bottom of the headunit with double sided tape (You could probably put it under the dash, just be sure to leave enough slack to plug in the other connectors)
From there, I ran the harness across the top of the A/C unit and behind the glove box. Next thing was to locate the microphone and the control pad. The mic should be up high, and I thought the controls were easiest to reach up top too, so that where I put them (see first pics). I ran the wire above the headliner (don't freak out, it's not that fragile) and down the A-pillar. The mic has an arrow that should be pointed at the person doing the talking.
The control pad harness is shorter than the mic, so it just reached the dash. I ran both wires inside the dash by passing it around the rear edge of the lower dash piece behind the weather-stripping.
Once everything is behind the dash, plug it all in and secure the blue box. I assume this is the Bluetooth receiver as it has an FCC label on it and it says Motorola on it.
I pulled out the factory amplifier while I was in there. This also gave me more room in front of the ECU to put the blue box. I used the supplied double-sided tape to stick it to the ECU. In that pic it was actually to close to the glove box and interfered with it closing properly. I re-stuck it further to the right. Double check all connections, put the dash back together and your done with the install!
The only thing that didn't come in the box was operating instructions. There are five buttons on the control pad. Volume up & down, green phone, red phone, and the centre Toyota button. Most features are voice controlled and after playing with it for a bit you'll get the hang of it. I used it tonight after the install to talk to a friend and the sound was great on my end with no complaints from him either.
My truck has an aftermarket headunit and I unplugged/removed the factory amp. When the Bluetooth unit is in use it kills the music to the front speakers and uses them for the call. The rear speakers still play music at regular volume. I assume the mute wire input would allow it to mute the music during a call. I have my headunit set up with the speakers faded to the front (5 out of 15), so the rear speakers aren't that loud anyway. The volume controls on the control pad allow you to adjust the volume of the call too. When my friend called tonight, the music faded to the rear, the Bluetooth lady announced the phone number that was calling, and I accepted the call with the green phone button. I hung up with the red. The green button will also redial the last call. You can program contacts into the unit, but I don't think it will import your phonebook.
