Hello, has anyone installed an OEM rimless rear view mirror in their m2c or m2cs?

Found the following product which looks compatable:

I can't recall if it was @dadvibes did it on his C and then on his CS noticed the CS has an extra camera on the mirror housing.

I have it installed on mine

Neither of them corresponds to the rimless mirror...

Awesome thanks. Anything to not when installing? Seems pretty straight forward.

Yep, that was me. I performed this retrofit on my M2C. I kept the mirror for my CS, assuming I could just pop it right in. However, I discovered that the CS has an additional camera module on the back of the mirror for automatic high beams. So when I installed the frameless mirror to test, it threw an error on the dash.

Looking at the connections, the camera module on the back of the CS mirror appears to utilize two additional wires that are not present on the US-spec semi-frameless mirror, the EU-spec frameless mirror, or the OEM mirror from my Comp. It is potentially possible that the camera module could be swapped to the frameless mirror and the two additional wires added to the circuitboard. However, I haven't had time to tear down and inspect.

If you're in the US and need fully functioning US homelink buttons, it's not nearly as plug-n-play as you'd think. The frameless mirror is EU-spec, utilizing different Homelink coding (I learned this the hard way). To fix this issue, I had to buy a US-spec semi-frameless mirror and swap the circuitboards.

If I recall, there might be a US spec frameless mirror you can purchase. But you'd still have to figure out the additional camera module wiring that the Competition mirror doesn't have.

My car is US spec i use EU spec mirror, totally plug & play.

Wait, your US Homelink buttons work with an EU spec mirror? That doesn’t make sense. What P/N is your mirror?

And the Comp doesn't have the additional camera module that the CS has to deal with. So, regardless, it's definitely not plug and play for CS owners.

He's probably commenting not understanding that he has a Comp and we're trying to figure out if this works on a CS even with the fact we have the additional camera. Not flaming anyone, just pointing out this fact.

That's the gist I'm getting, as well. I just don't want CS (or even Comp) owners to read his comments and run out and buy one, thinking they can just plug it in and it will work. I know from direct experience that:

1) People tend to confuse the semi-frameless mirrors (P/N: 51169476753 / 51166830616 / 51166995975 / 51169459440) with the fully-frameless mirror (EU-spec P/N: 51162471107 or US-spec P/N: 51169476754).

2) If you're in the US and want the fully-frameless mirror that works with US Homelink, you have to buy 51169476754 (credit to agent_orange for discovery). Alternatively, you can buy the EU-spec one (51162471107), but then you'll have to swap the circuitboard.

3) In either case, CS (and possibly specific spec Comp) owners also have to content with the mounting bracket that houses the automatic high beam camera module and contend with the 2 extra camera wires.

I know I sound like a broken record, but I want to make this painfully clear to others, before they spend their money.

All that said, it does look like Tano was able to do this retrofit with the US-spec semi-frameless mirror, including the camera module. HERE is a link to his post. I imagine it could also be accomplished with the fully-frameless mirror (51169476754), but can't say for sure. I'm hoping to dig back into this project, sometime soon.

The author of the post asked about m2c and m2cs, I answered based on m2c.
I did not deal with anything, mount code and work, I do not remember P/N, I installed it 2 years ago.

Will 51169476754 work for US spec comps and OGs? Assuming that the proper repinning is done?

Yes, from my understanding, it will work for the Comp w/US-spec Homelink. I imagine it should work with the OG, as well. However, I don’t have direct experience with that car.

Confirming that 51169476754 works flawlessly on my OG LCI M2!

Dope! Glad to hear it worked!
