2021 TRX Uconnect 4 → Uconnect 5 + Digital Cluster Retrofit Issues — No 360 Cameras, Cluster Nav or Album Art

[Andresfrvnco]

Hey everyone, looking for some help from anyone who has completed the Uconnect 4 → Uconnect 5 / digital cluster conversion on a 2021 TRX.


Here’s my setup:

• 2021 Ram TRX
• Uconnect 5 12” Display — 68526598AC
• Uconnect 5 Radio Module — 68583503AE
• Radio software — T25
• Newer CVPM / 360 Camera Module — 56029968AF
• Digital Gauge Cluster — 68510283AH
• TRX Digital Cluster Mask — 68620863AA
• UC4 → UC5 conversion harness
• Truck originally came with factory 360° cameras

I paid $550 for the physical installation. Everything powers up and the Uconnect 5 screen and digital cluster are installed and functioning, but I currently have three main issues:

1. Factory 360 cameras are not working correctly
2. Navigation/map does not display in the digital cluster
3. Album art does not display in the digital cluster

I first spoke with American Radio in Roswell, GA, but they told me they could not perform the Mopar recalibration/VIN coding needed for this retrofit.


I then took the truck to a Dodge/Ram shop/dealer with wiTECH. wiTECH does recognize both the RADIO and CVPM in the network topology. The RADIO shows orange and the CVPM shows yellow.


They attempted the camera calibration. From what I was told, they were able to get the front and rear cameras through calibration, but the left and right/mirror cameras would not complete. They also said the radio does not seem to be communicating properly with the rest of the system.


They were looking for something they could change/add through the factory configuration or sales codes, but because the truck is a 2021 VIN with newer 2023-style electronics retrofitted, they haven’t been able to get everything communicating correctly through normal wiTECH programming.


They quoted me another $450 for programming/calibration, but at this point it doesn’t look like they know how to finish the retrofit.


What I’m trying to determine is whether this sounds like:

• UC4 → UC5 conversion harness / pinning issue
• CAN-bus communication/configuration issue
• Missing or incorrect CAN interface
• Missing/incorrect 2-pin Ethernet connection between the UC5 radio and digital cluster
• BCM configuration/model-year issue
• CVPM configuration issue
• Something specific that needs to be changed using AlfaOBD/CDA rather than wiTECH
• Or another part/configuration I’m missing

I do not want the dealer to restore the truck completely back to its original 2021 configuration or blindly flash modules, because I don’t want the retrofit settings overwritten.


The fact that I’m missing both navigation AND album art in the cluster makes me especially curious about the radio-to-cluster Ethernet/CAN connection. And since the front/rear cameras will calibrate but the two mirror cameras won’t, I’m wondering if that points toward configuration or wiring rather than the CVPM itself.


The radio is T25 software, so from what I’ve researched it should be the correct generation rather than one of the newer incompatible U-series radios.


Has anyone with a 2021 TRX successfully completed this exact setup? If so, what did you have to change/program to get:

• all four cameras recognized
• 360° surround view calibrated
• navigation in the digital cluster
• album art in the digital cluster

Also, if anyone knows exactly which AlfaOBD/CDA settings, CAN interface, harness connections, or Ethernet wiring I should verify, I would really appreciate it.


I’m in the Roswell/Atlanta, GA area, so recommendations for someone locally who has actually done this retrofit would also be extremely helpful.

2021 BCM doesn’t support album art or map in cluster. Need 2023 BCM and the settings I list in the linked thread below changed. Or instead of the BCM replacement, an interface from @skuppy069 which will allow those functions to work.

Original SGW also needs to be bypassed permanently as it blocks Ethernet communication between the radio and cluster.

For the cameras, model year in BCM needs to be set to “2023” via AlfaOBD and then CVPM calibration done.

First thing to know, mileage correction can’t be done via AlfaOBD yet but I was told it’s being worked on. With that out of the way, let’s look at the stages. Stage 1 (cluster only): To do this at its most basic level, you only need the cluster and a custom adapter harness from Jimmy07. To...

I have both the Skuppy cables and the Jimm07 cable instead but not the SGW cable. I believe that’s what the issue is. Waiting on that to come in now.

What’s weird is that I don’t have the camera button at all on my screen nor do the cameras come on at all when I’m in reverse.

That’s because your model year isn’t set to 2023.

That’s because your model year isn’t set to 2023.

Gotcha, so I just need that final step and I’m set?

Yes, that will get the camera functions back on screen. You will still need to calibrate the CVPM for the 360 view to work since it sounds like the dealer wasn’t able to do it. But backup camera will work and you’ll be able to pull up all the individual cameras to make sure they all work on their own at least.
