My new to me '20 GT has the same plastic nosepiece behind the rearview mirror as the Bentayga so I could use the same style integrated dashcam again. This one was on sale for $129.99 a couple days ago so I ordered it instead of the FitcamX brand I used before (same specs):

The plastic piece that the dashcam replaces is the same used by Audi and has an Audi part # inside. If you order the dashcam specifically for a Bentley you'll pay over $100 more and receive the same item.
Installation takes less than 15 minutes and and it plugs into an existing connector so there's no wiring involved. The black plastic piece above the mirror pops off first, then the collar and then the nose piece. Next the harness is plugged in and everything snapped back into place.

The large black piece comes off first followed by the collar & then the nose piece.

Hi Bruce, that looks great. Do they make that for a gen 2 as well?

 

I looked when I had one but found nothing.

 

Ok thank you!
