That’s what I was thinking, but wasn’t 100% sure. I am waiting to see a HD with both. It does make me wonder if there will be 3 different CHMSL with camera options for HD now. 1 with just cargo cam, 1 with just rear view, and 1 camera that will have both rear view and cargo.
Going by the online build configuration tool (which has been wrong before), the digital rear view mirror can only be optioned on trucks that have surround view, which automatically come with the cargo camera. That would mean there is no CHMSL with only the camera for the mirror. There would be 3 different CHMSL with camera part numbers, though:
1) The CHMSL with cargo camera for trucks not equipped with surround view.
2) The CHMSL with cargo camera for trucks with surround view- because the camera is digital, and bigger, with a different camera housing than non-surround view trucks
3) The CHMSL with cargo camera and digital rear view mirror camera for trucks equipped with surround view
We have also determined on the DT trucks that the digital rear view mirror and it’s CHMSL can be retrofitted in 2019-2020 trucks easily with no BCM settings changes (assuming you already have an auto dim mirror). The mirror plugs right into the same connector as the existing mirror, and is connected to the camera with a single fakra coax cable. It should be the same situation for the HDs.
