Does the CMHSL need power for rearview camera to work?

[LBC_Jeff]

As the tile suggest, I’m curious if I need power to the CMHSL for the digital rearview camera to work.

I picked up a used CMHSL I wanted to just plug the camera in to see if it worked and it didn’t so I wasn’t sure if I needed to feed power to it to make it work or if I have another issue

Thanks
Jeff

The Camera use a FARKA connector - so you need that cable connected at the mirror.

Thanks. That’s what I was thinking. I’ll chalk it up to the rearview mirror is defective or the Linbus thing won’t work on the 3.0 mirrors. I’ll get my hands on a mirror from a 2021 this weekend and see if it works. Thanks!!

Answer is no.

If it’s the 3.0 mirror the cameras have to go through the video processor module under the driver’s seat.

Yep I believe it is a 3.0. Makes sense now. I picked up a 2021 mirror and the camera in the CMHSL didn’t work but I got a CMHSL from a 2021 and it worked so looks like eBay will be seeing a 3.0 mirror and CMHSL pretty soon!!
