Success!
The parts came in today and I am happy to report a successful installation on an '04 vert with BMW Assist.

Of course the assist module had to come out, but no big deal there.
It took about 2 1/2 hours because the instructions on Adam's website aren't entirely correct. On his, the BT and assist modules appear to be right behind the driver's side rear passenger. In my car, the module was in the trunk next to the subwoofer. You can see the spot if you look in the trunk. The driver's side of the trunk liner has a bulge in it next to the subwoofer. Of course, I had the entire rear seat out before I learned of this discrepancy.
The center console setup was actually pretty easy. It is a total of six screws. Four in the ash tray and two under the shifter plate. I'm probably going to leave the pairing button under the console rather than cut a hole. If I need to get to it, I just have to remove the cup holders. The e-brake boot and shift boots both came up pretty easily so don't worry about tearing or breaking anything when you pull on them.
The Assist module itself was quite a pain in the a$$ to get to because of its location and the fact that you have to remove the sub to remove the trunk liner. I just folded the liner over a bit and stretched as much as I could to reach the module rather than remove the sub. I broke one of the connectors while removing it, but it's not one that's necessary for BT. I was able to fix it, though, so no worries.
Overall, a combination of Adam's 'vert pictures, his sedan pictures and the BMW instructions were enough. None of them give a complete picture because there really aren't any complete ones for a 'vert. With the exception of the module location, though, they were good enough.
Some things to know when you start working:
- Some of the instructions will make no sense until you look at the wiring, but then they will make complete sense
- There is a second cable wound up with the pairing cable that looks EXACTLY like the one that you plug into the BT antenna. It is an extra cable and is not used. Adam references it in his sedan instructions.
- There are three round connectors that can be plugged into the BT module, but you only need the white one. That is the one that is strapped back. The other two are used for BMW Assist.
- READ BMW'S PAIRING INSTRUCTIONS. I sat there for five minutes before I RTFM and got it working after it was all plugged in. You have to press the pairing button before turning on the car.
- You need a phillips head screwdriver, a small flathead screwdriver (to pull out the trunk liner studs), and an 8mm socket screwdriver. No other tools are necessary unless you do it at night in a dim garage like I did. I had to use a flashlight in the trunk.
Overall, it was not a technically challenging project, but did require a lot of patience when removing Assist and placing the BT module. Voice dialing works better than I expected. It's late and I'm tired so I won't try it on the road until tomorrow, but I am very pleased that it worked so easily.
Sorry for any typos. I'll correct those tomorrow.
Edit: I've added some pictures.
1. In the first picture, you can see that there is no BMW Assist module behind that plate. The silver unit is the roll bar housing.
2. The second picture shows the raised bump in the trunk liner next to the subwoofer.
3. The third picture is the BMW Assist module. It sits at an angle. There are two connectors on the right and one large one on the left.
4. The fourth picture is the BT module in place. I used the clips that held the Assist module. You have to relocate them to the alternate holes because the BT module is about 3 inches shorter than the assist module. Not to worry, the mounting bracket is designed for this module and the clips and holes line up perfectly.
5. Another close up shot of the module. The wire with the purple square on it is the one I broke. It was at the bottom right corner of the assist module and I could barely reach it. The end came off, but I was able to get it back on for later reattachment of the assist module.
