I was able to get an 8.4 radio from a 5th gen installed and working on a 4th gen, so here’s some info on that. This is the UAV 8.4 with navigation. A few things to let you know about this, first:
1- If all you’re looking to do is have an 8.4 upgrade for CarPlay or Android Auto, there’s really no advantage of installing this instead of the UAQ or UAS radio. The only reason I did this is to ultimately get the factory surround view from the 5th gen working on my 4th gen, and the UAS/UAQ radios don’t support it, so *hopefully* this thread evolves into how to do that.
2- The UAV 8.4 is three separate parts: the display screen, the radio module, and the LVDS cable that links the 2 together. A “Y” conversion harness also needs to be made that plugs into the harness connector for the HVAC hard controls so that same connector can be plugged into the display screen (more on that later).
3- The back of the center stack with radio bezel has to be modified to be able to screw the display screen to it.
4- The windows version of AlfaOBD is needed to make the necessary change to get the display screen to work. At this time, the Android version isn’t capable.
5- I haven’t tested this on any other vehicle except mine- 2017 Ram 2500 Tradesman. I drove around for a day and a half with multiple drive cycles to make sure everything I could think of works the way it should before finalizing the install.

Part number for the display screen is 68356773AD. The radio module is 68307655AI. The LVDS cable is 68082364AC.

A conversion Y harness needs to be built for the HVAC/Hazard switch controls. The two circled connectors are the same 8 way connector that contain the same circuits, just with different pin locations, and they both need to be plugged in. yuEl6tW.jpg The red circled connector is the original one that the factory dash harness plugs into. Here’s it’s pin layout- z5gnK5e.jpg

Here’s the pin layout of the purple circled connector on the display screen- dzz3c8o.jpg

You’ll have to build a harness that plugs into the female 8 way dash harness connector, takes those circuits, and branches them off to the appropriate pin locations on both circled connectors. HqoOBlH.jpg

Parts to make the harness:

(1) Male 8-way connector- https://www.digikey.com/products/en?keywords=309681081

(5) Male terminals- https://www.digikey.com/product-det...tors/2-1419158-5/17-2-1419158-5CT-ND/11492481

(2) Female 8-way connector- https://www.digikey.com/products/en?keywords=307001081

(10) Female sockets- https://www.digikey.com/product-det...amp-connectors/1393366-1/A101883CT-ND/2700940

Tessa tape

20 AWG wire


Normally, the radio gets mounted to the dash opening, and the center stack gets clipped to the dash and the radio. With this two piece radio, you’ll have to just stuff the radio module into the hole sideways,and leave it laying in the dash. I zip tied mine down to the tubular dash frame with a long zip tie. The display screen will have to get screwed to the back of the center stack radio bezel. To do this, you have to build up some mounts. This is where you can get creative if you want find a better solution. I used Loctite plastic bond, built up the mounts, sanded them with a dremel, drilled the holes, and screwed the screen down. First, I cut the four circled clips off and remove the two screws the arrows are pointing to- fV99GnC.jpg

The four corners to build up with plastic bond- rcb2oQa.jpg

The same original radio connectors are plugged back into the new radio module: white to white, mustard to mustard, etc. Also, don’t forget to plug the LVDS cable in from the screen to the radio module. ioZKxuX.jpg

Finally, with the windows version of AlfaOBD, connect to your BCM. Then, switch over to advanced mode. Drop down the body control list and choose MY2017 Pacifica (all the way at bottom, I believe). Select car configuration change. Then select “cabin net- display screen module” and enable it. This setting isn’t in the Ram BCM settings list, and the Android version isn’t capable of making it show up by connecting to a different BCM.

This radio seems to take settings from the BCM right away, for my truck anyway. The UAQ that I had would take about a day for everything to take.


Next up, I’ve got the fully loaded camera mirrors from a 2019 HD Ram, then I have to find the front and rear digital cameras, and a central vision processing module, and see if I can get the surround view working.

I started pulling together the parts list a while. The CVPM is 4672644AI and goes for around 500 new but can be had much cheaper. The CVPM is located under the driver's seat on the RAM HDs. Keep in mind, the part number comes back as a "forward facing camera" but I've verified it at the dealer.

You'll need a new tail gate camera (has an additional coax output), a new cargo cam (also has an additional coax output), and the front camera. Then it's a bunch of coax cables to connect everything and then the output goes to the red connector on the back of the stereo modules.

I’ve also got all the part numbers. I’m finding CVPM for $350 new consistently, and I’ve got emails out to junk yards, since they don’t usually list specific modules like that in car-part. I’ve got the front and rear cameras coming (same part number), the loaded mirrors from an HD, and a bunch of lengths of fakra z cable (universal fakra connectors). I’ll be using a 5th gen tailgate handle to mount the new camera in, which has to be fabbed in, and I’ll have the remote tailgate release working from the factory fob and an aux switch. I also have the measurements for difference in height between the side mirror cameras and the front camera so the image gets stitched together correctly. I just need to figure out the downward facing angle of the front camera, still. This is definitely going to be the most time consuming, multi-faceted planned out mod I’ve done, and won’t be practical for most.

I will be following this one along because I already started looking for the parts, too. Passively at the moment but definitely something I am considering adding.

One thing to note, the UAQ radio also has the "red" fakra input connector from the CVPM. The UAQ radio also shows the "Surround View" button in the Controls section when the CVPM is activated in the BCM so it may be possible to get it working with the UAQ radio but maybe not with all the camera angle controls that the UAV radio will have.

Also, if I did this on the 1500, I would need to plug it in downstream of the module I needed to make for the blind spot monitoring to work. I would guess the CVPM will also have vehicle line mismatch issues on the DS 1500s.

It could be possible for the UAQ. I did get the surround view control to show up when I had my UAQ, but I couldn’t get the backup camera from a 2019 HD to work no matter what settings I tried, makes me think it can’t happen on the UAQ.

That's good to know. I wonder if it has to do with the LIN BUS messaging differences though I doubt it since the LIN BUS connection goes to the BCM if I recall correctly. The camera works without issue on the UAV radio?

My original camera is working right now on the UAV with the original settings. The 2019 HD camera, that plugs into the red fakra, also works on the UAV without making any settings changes, and I’m not exactly sure how or why that’s possible. The 2019 HD backup camera is also a different part number than the backup camera needed for surround view, even though they are both run by coax. My original plan was to only add the 5th gen tailgate handle, which is why I bought that 2019 HD camera, because the original one won’t fit. When I couldn’t get it to work with the UAQ, that’s when I decided I might as well go all in on this.

That's interesting. From looking at the connections to the rear camera and cargo camera for the '19+ HDs, it seemed like they had both coax and the 6pin connector. Is that not the case? Does the "new" tailgate camera only have the coax fakra connector?

The 2019 HD’s will use one of three different backup cameras. The one used for surround view, which has only a coax connector. The one for 2500/3500s with the 8.4 screen, but without surround view, which has only a coax connector, and is not interchangeable with the surround view backup camera. And the one for the 5” radios, which is the old style with only the 6 pin connector like we are used to seeing. The cab and chassis trucks and the pickup box delete trucks that have surround view option will have the UAV radio with the regular 6 pin connector backup camera that is user mounted, and the surround view is programmed for 270 degrees instead of 360.

Got any pics of it installed and powered up ?

I tried this on my 2018a few weeks ago with uaq radio and the icon showed up a day later etc .
When I pressed the soft key it displayed my backup camera which is the one from the factory .
I wonder if the camera you used didn’t work because it wasn’t plugged into the cvpm?
Or does it even plug into the cvpm?

Here’s a pic when I was testing it with the 4th gen HVAC controls. Note the module sitting in the opening sideways. I just tucked it further back in the hole for final install- el2qmEV.jpg
Here’s a pic when I tested the HVAC controls on the 5th gen radio bezel- AeFHSSj.jpg
The 5the gen bezel would have to be trimmed with a dremel to fit the 4th gen center stack, and it also has white backlights that contrast with the blue backlights on the lower switch bank.

The camera I used is the one that plugs into the red fakra connector on the back of the radio. The UAQ radio that I had would take a about a day, and multiple drive cycles for the backup camera to work any time I unplugged the radio and plugged it back in. It’s very well possible that I just didn’t give it enough time for it to work. I just sold that radio, too, and I should have just kept it to test all this out with both radios...
