FWIW, I just saw a video with a 2022 3500 dually with air ride that has off-road pages...
@Jimmy07 I know you've been focusing on the UC5 upgrade, is there any progress with Alex/AlfaOBD on the possibility of seeing off-road pages and/or the forward camera on the 19-21 3500? P.S. We also found the trailer light check didn't work on my truck.
I do know that the radio application version needs to be 39.x.x for off-road pages to be available on the radio. After that, I’m not exactly sure what makes them operate properly. It’s definitely only VehConfig 5 off road pages present that needs to be set to yes. I have them on my 2017, but the gauges are in metric, and the pitch/roll doesn’t work. Also, on each startup, it takes a few minutes for it to show up in the apps section, and it always populates as the last app on the last page, even if I previously moved it to the first page.
Alexey’s only input for all of those features is that the BCM isn’t capable. But, we know that a 2020 2500 and 3500 use the same BCM’s, so that doesn’t explain the front gridlines behavior. It’s possible there’s something different with the BCM between 2020 and 2021 for the trailer light check though.
I have an arduino in between the can ihs network and the CVPM on my 2017 so the surround view will function, and the front gridlines work for me. Let me see if I can flash the arduino to forward the D2 vehicle line (3500) to the CVPM instead of DJ vehicle line (2500). If our suspicions are correct, the front gridlines should stop working.
