Backup camera on M37x
The backup camera on my wife's 2012 M37x works intermittently, and this is a major problem for her because she's short and cannot see over the back, so she is afraid to drive. The dealer wants over $1000 which, for elderly retirees like us is out of consideration.
Another thread suggested testing the camera by turning the audio off; then holding down the settings button, while turning the volume control. This supposedly enters a hidden menu. Tried it several times with no result. I have located a used camera, but need to know if the camera is th eproblem.
Anyone have any ideas?

Hello and welcome to the site.
Being that the camera works intermittently leads me to suspect a compromised wire/connection. The first thing I would check is the pass-thru wiring harness between the trunk lid and the car body:
I know some G owners have had similar issues with the wires in that harness breaking. Due to the flexing of the wires from opening/closing the deck lid, they become "fatigued" and fail.
The camera itself only has four (4) wires:
RED- CAMERA POWER (HOT in REVERSE)
WHITE- GROUND
YELLOW- CAMERA IMAGE SIGNAL
BLACK- SHIELD (basically a ground)
If all the wires check out, then we can look at the diagnostic (hidden) menu.
This should get your started for now...
