Have mercy on my soul. I'm wanting to severely DIY my rearview mirror to mount my Uniden R7 inside the mirror and allow the display to shine through the mirror.

I ordered a replacement mirror for testing, but before I do this I wanted to know if anyone has DIY'd the mirror to put a display in it, or screwed with the mirror at all in some fashion. I really want to know if the dimmable mirrors have a black backing that can be removed or how it works so that I can (potentially) have a friend cut some two-way glass to match and replace it.

The second part of this project is to cut into the plastic housing and make a mount for detector. Thank you for entertaining my curiosity


EDIT:

I've done more research. I learned how the autodim function works on the mirror: https://www.youtube.com/watch?v=tI3cR9KhrdY
So what I need to do is see if I can either:
A) remove any film on the back of the mirror, if it actually exists. seems unlikely that will work.
B) cut the mirror to reveal the film and replace a chunk of the mirror with a two-way mirror. Or if it looks doable, completely replace the mirror with a two-way mirror.

I watched how you cut glass and more specifically, how to cut curves into glass, so I'm interested in how this will turn out.


EDIT 2:

And I've found a deconstruction of the Uniden R7.

The forum post is great because it shows the buttons are only attached via a connector with exposed wires. This makes me think I'll be able to lengthen the cables for relocation.
