My 2020 GMC Sirerra has a great camera system but no recorder. Has anyone found a video recorder compatible with GM'* Surround Vision? Does the Surround vision have a video output connection?
Any help would be appreciated.

The video processing control module is connected to each camera via a shielded coaxial cable. The coaxial cable provides power for the camera and also carries the video image from the cameras to the video processing control module for processing. The video processing control module will then send the processed image output to infotainment system via another coaxial cable.

The video processing control module receives CAN information from Rear Park Assist object detection module and Steering Wheel angle from body control module during Reverse. A warning triangle may display during the 360 surround view screen if Rear Parking Assist has detected an object during a reverse. This triangle changes from amber to red and increases in size the closer the object. Also a dynamic guideline is displayed in Reverse to show the projected path of the vehicle.

If equipped, the video processing control module system may have a memory card receptacle (with XVR) located in the trunk. The memory card receptacle interfaces with the video processing control module via a USB cable. The memory card receptacle also receives fused battery voltage and ground from the video processing control module. The video processing control module uses the memory card as a mass storage device, similar to a USB storage device. SI Document 4997657. Not sure if this is what your looking for. Hope it helps.

Hello,
Thank you for your reply. GMC does not offer the surround vision recorder in the Sierra. There are other GM models use the same surround vision system and offer a recorder such as Cadillac. What I am trying to determine is if I can utilize the Cadillac recorder and install in my Sierra and what it would take to do so, equipment and software. If that'* not possible, then I would have to settle for an aftermarket DVR that can capture the video if one exists that will work with GM'* Surround vision..
Any ideas?
Thank you

I can tell you that there is an unused port on the video processing module on your truck, that would be used for an external memory device. This is a standard module across the current year GM products. However there is a TON of software on these modules, to make those CGI like images on your screen. The software is different for each model / options of each vehicle, including things like your truck is a truck not a cadillac sedan and so forth. From past experience, I know GM usually disables unused ports like this via software settings.

But, if you can find a GM recording device made for the same module, doesn't hurt to plug it in and try. Odds are though that you will have to wait for GM to release the software to do what you are thinking of. (Maybe a future year pickup will include it)
