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. The red circled connector is the original one that the factory dash harness plugs into. Here’s it’s pin layout-
Here’s the pin layout of the purple circled connector on the display screen-
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.
