Here is about a 5minute video of my Eonon GA6166 install appearance and some of its capabilities

Not perfect or flawless but for just under $300, it's a

from me.
PS: I put the anti-glare screen on after this video and it helps.
Here is a new photo of my fitment after using a different set of screws (actually JL Audio speaker screws) that screwed down into the Eonon frame and slightly into the factory retainers.
What this did was allow a little offset/setback (longer screws) from the factory frame point and allowed the Eonon to sit a little more forward at the top which for me, prevented the lower edge gap that I was previously experiencing.
Also, with a little bit of voltmeter sleuthing I determined it is the BROWN wire from the Canbus module and also the BROWN wire embedded in the Fakra cable that is the reverse trigger.
The BLUE wire of the below TPMS unit tapped into the BROWN wire of the Fakra harness (HU rear camera trigger) and my gray wire was connected to ACC power.
I got the TPMS unit functioning great!
The little brain box fits nicely in the driver side cubby on the metal panel that the factory amplifier is mounted onto.
