Yes. That is exactly the upgrade I did on my 2020. Wams programed. If your lucky you can find a vpm that matches your trucks specs you may not need to program.

You know what you could do... you could get a oem video mirror and mount a rear view mirror camera in grille. When you want to see front of truck you can toggle video mirror on.

If you do not have a bed view camera you don't have a VPM. No one I know has tried it without having a VPM. If you wanted to try to do this you need to study wire diagrams and create the harnesses. You would probably need a programmed radio and vpm.

For me my door harness had the coax built in. the body harness car side where door harness connects was empty no coax. You could insert a coax but I don't think I could get right length and connector tip to "pin" the body harness. You are right that would be a cleaner easier way if you could find the right coax tip.

Nice work! Now I want to see someone try that has no VPM. WAMS is the best right?

I tested a 10" tahoe screen plugs matched. Parts of it worked. Tahoe is global b tech our trucks are global a. So I tested a CT6 screen, I think I had to modify power plug, parts of it worked. This is CT6 is global a, I sent a Cadillac CT6 screen to WAMS so they could test. I believe WAMS has figured how to rework the resolution the in radio. So a switch to 10" with oem functions would involve a new radio box (right side of dash) or radio box programming.

You need WAMS White Automotive and Media Services. I added factory heated rear seats and added cool seats to my heated with programming with WAMS+ autosync.

I think it is the radio, 50% sure. A 2019 vpm would not work in a 2020. A 2021 vpm works in a 2020 too. The wireless carplay that wams has works for 2019-2022 (non- refresh) but WAMS states 360 cam will not work on a 2019. That is why I think it is worth trying a wams wireless carplay radio in a 2019 and try the upgrade. Ask WAMS.

I bet 2023 has a different camera part number. You probably need to buy a 360 cam from a 2023. Just a guess. I know originally I had some issues when making mine but I turned car off then hooked up trailer then camera then all worked but sounds like you tried that.

Hello. what did you need? this upgrade wont work on a 2019. Will work on 2020 and 2021 maybe 2022. My truck had a package that was bedview and 2 trailer ports it was a 5 port VPM I was able to swap a 10 port VPM and gain 360.

I added a oem HUD to a 2020 silverado that didn't have HUD. How do you have HUD cut out with no HUD? Are you sure you aren't talking about proximity warning light cut out. that cut out is much smaller than HUD cut out.

yes got it working perfectly like from factory just need parts listed and autosync device from WAMS
