Dude - you're a legend. That's awesome. I am not sure about my ability to do that kind of soldering, but it's inspiring. I haven't got a USB port in my cupholder, so I'd have to think about cutting. Does the Pi pass through enough power to keep your phone running with Waze/spotify etc. running?
I was thinking of using one of these to feed the Pi.

My RPi now sits semi-permanently installed Velcro'd on to the top of the lower air-bag under the dash, power and data from the OBD port, internet and data to the phone over USB.
One additional thing I did was to re-wire the USB port between the cup holders so that it's connected to the RPi. I found that Wireless CarPlay, which connects by default and keeps trying to connect, perhaps understandably, messes with the WiFi hotspot function on my iPhone. PTF mentioned that you can do tethering through the USB port and I've found that this works great, even with CarPlay running wirelessly. To do this I ordered a replacement cable that clips in the back of the USB socket, unclipped the stock cable and just left it there, cut the new cable and soldered on a USB plug to go in the RPi.
