I hear you about not wanting to have wires run everywhere. It is unfortunate you are not willing to either perform the installation or hire a professional because it opens up a lot more options for you.
I personally use the Blackvue system as well. It can be installed to be very out of the way and hide all wires with a little effort. I had mine done professionally and they tucked in the wires in the auto-pilot channel that runs down the front of the windshield.
It is not cheap though. It runs about $425 for the 2 channel 4K camera. But I like that I can drive into my garage and the wifi in the unit connects directly to my home network and I can run a program on my home server to automatically download and archive all the video footage automatically.

I use a 512GB micro SD card, that is designed to be used in extreme temperatures, since it can get hot in the car and damage the memory if not rated for those temps.

Instead of the factory mount for the camera, which will work for most people, I spent the extra money for a good mount that works on the rear-view mirror bracket by blend-mount. I did not want anything sticking to my windshield.
THat has to be ordered from Blendmount or the
Dashcamstore.com (which was cheaper) and you have to select the specialty one with specifics for your car to get the right hardware for the Model X.
But the results are stellar. It is tucked well enough under the AP camera and behind the rear-view mirror. The cables are all hidden, and I get very good view both front and back. It was worth it for me to get the added visibility in the event of being rear ended (my only accident in 30 years was from being rear ended).
I don't have any pics handy at the moment, but will try to post some later.
