Thanks all for the feedback! I just installed the blendmount and wire tapped into the mirror. Works great!

I probably spent an hour trying to carefully remove the plastic trim without breaking the clips. A small, flathead screwdriver works great for this. Simply wedge the blade between the clips near the base of the mirror and twist the driver until it pops. It's a bit anxiety inducing, but apparently the plastic trim is only $20 online so it's not the end of the world if it breaks.

The wiretap is designed to feed into the wiring harness just above the mirror mount. The DIY instructions in the other threads (posted above) called for the wiring harness connector to be unplugged, but it was so tightly connected, I was not able to disconnect it. Instead, I simply used the small pins and spliced into the red and black wires without needing to disconnect the harness. The pins are small and stiff enough that you can use plenty of force to get a good connection. Just make sure the radar powers on and the connection isn't loose before you reinstall the plastic trim (It's a PITA).

PSA - The PA state troopers use K Band on the Turnpikes, which really surprised me. Normally, I ignore K band due to the large number of false signals, but you really have to really pay attention in this state. The signal strength is low, and almost comparable to MRCD.

Safe travels and happy driving!

I did the same, I wasn’t able to get the harness unplugged so I just slid the taps in in-place. Had to be careful to get a good connection but I wasn’t confident I could un-clip the harness without breaking something. Some people in that thread also suggested removing the entire mirror but this seemed difficult and unnecessary.

For removing the other piece I had no trouble but I have a plastic trim-puller tool set I used.

Just wanted to post a picture of my setup and add a little info. There's great info and install pictures in this G20 thread.

Basically what I found out is that the upper purple connector for the rain sensor is always on, which is okay if your radar detector shuts off, but not good if you have something that doesn't power off like the Escort dash cam. Mine was taking video of my garage for hours.

It seems like bigger connector below the purple one is a better place to tap because it actually switches off after a while. I locked the car and took a 7-8 minute walk and it was powered down. It turned on automatically when I opened the car door.

Also FYI, if your devices do not work with the 12v cigarette lighter outlet by the cupholders, that is probably due to the metal contact screw at the bottom of the socket being too short. I've seen other threads where BMW has replaced the contact screw with a longer one so your 12v plugs will work.
