HOW TO: Add Digital Rearview Mirror

[vincentw56]

I just read through all 24 pages and it still isn't clear. I have a 2020. If I buy a *NEW* BCM and get it programmed at the dealer, and then I do the rest of this mod (Mirror, CHMSL, FAKRA) will l be able to retain my auto dimming side mirrors?

I can't tell if there are just two ways to do it (USED BCM and jimmy07s harness or a new BCM) and they both produce the same result, or if the NEW BCM produce a different result (aka keeping the auto dimming function)

Thanks!

It's pretty simple and straightforward as it's written. You need either another BCM and Jimmy07's harness or a 2033+ BCM to replace yours. It must be a 2023+. You can't just buy a new BCM for a 2020. Or you can send your current BCM to Jimmy07, and he will upgrade it. A dealer probably won't do that for you.

I swear I'm not trying to be a pain, but that still doesn't answer my question. Does doing either of what you just suggested let me keep my auto dimming mirrors? Or is that just not possible on a 2020?

Yes. And it was already answered above by MannyN. But to be clear, only by using a 2023+ BCM will you be able to keep auto dimming.

Ya sorry I just saw MannyNs reply now. Ok thanks gents. And a 2022 BCM wont work to keep auto dimming? 2023+ BCMs are all on backorder but there is a sale on a 2022 BCM for like 50% off on the MOPAR site right now...

TBH, I think a 2021+ should work. I think what I was getting confused was you need a 2023 Plus for the digital cluster gauge.
