Confirmed! The Dongar Mirror to Dashcam adapter for the frameless auto dimming mirror also works for the framed CX50 mirror.

I folks this is a question I had asked for a while and I saw another user recently post that they were able to do it on their framed meridian edition mirror. I have the NA Premium Plus CX50 and I just completed the install and everything works and fits very well!

I previously had a USB cable hanging down from the mirror connected to the plug in the center console. Now it looks so much cleaner with power running directly from the mirror.

Check out photos of the install and final product.
