How To: Install a 2018 4C (UAQ/UAS) Radio in 2013 - 2017 RAM

[DeereGuy]

For the 2018 model year RAMS, the 8.4 Radios were changed from the previous VP3/VP4 Harman radios to the 4C/4C-Nav radios made by Panasonic. The biggest advantage of these new 4C Radios is the support for Apple CarPlay and Android Auto. The radios themselves fit the same mount as 2013-2017 RAMS and the radios require no special programming to work. They read the BCM of the truck just like the VP3s/VP4s. However there are some known issues and components that need to be changed to make it work 100%.

Thanks to MPGRIMM2, RICKS RAM, 00R/T, and STDECO for volunteering to test these radios in their trucks. As a result, we have had them working in a 2013, 2014, 2015, and 2016 trucks. We have tested seats, backup cameras, cargo cameras, android auto, apple car play, and most of the radio's standard functionality in these models.

There are two distinct versions of the radio. The 4C (Sales Code: UAS) and the 4C-Nav (Sales Code: UAQ). The only difference between the radios is that the UAS does not have built in navigation and the UAQ does. Both units support CarPlay and Android Auto. However, unlike the previous VP3 radios, Built in navigation cannot be purchased and added to the 4C radio.


Components Needed

RADIO: 68331631AH (UAQ) or 68331635AH (UAS)
MEDIA HUB: 68328704AC (RAM) or 5XG28DX9AC (Compass)
MEDIA HUB CONVERSION HARNESS

RADIO
It is important that you get a radio that has the correct mount as the mount is now forged as part of the radio housing. Even though a radio out of an 18 Charger/300/Durango/etc will technically function the same as the RAM radio, the mount will not fit the RAM. Can these radios be modified to fit in a RAM.. Maybe, but I wouldn't recommend it. I broke a screen trying to transplant a UAQ radio into an existing VP4 mount.

It is also important that you get a MY18 radio. All MY18 radio part numbers start with 683.... The RAM themes are only available on MY18 year radios and the firmware must be at least version 18. There is a round colored dot on the top of each radio that has a number in it that reflects the firmware version that the radio had on it when it shipped from the factory. Anything less than 18.7 may have functional problems. It is possible to upgrade radios with older versions of software (I have upgraded to 18.14 all the way from 15.5 on one radio) but I also had one fail the upgrade process. Be wary of "AA" revision radios as they are really a crapshoot of what you are actually going to get.

As of now the radio can be purchased brand new from FCA. The cost is around $1200 for the UAQ, and about $100 for the hub.

MEDIA HUB

The media hubs in pre 2018 RAMs will not work with the 2018 Radios. Unfortunately RAM changed the form factor of the media hub in the 2018 RAM Trucks. The 2018 hubs are oblong in shape compared to the square 2013 - 2017 hubs. The closest compatible hub that will fit the existing opening is the compass hub. It is not an exact fit, but it generally fits. Changing the hub in a center console truck is easier than changing it in a jumpseat equipped truck.

The connector on the rear of the media hub is also different, so a conversion harness will need to be built to adapt the current 6 pin connector to the 8 pin on the new hubs.

Jump Seat Insert Replacement
Trucks that have a jump seat can order part number 68376066AA which is the insert with the correct cutout for the 18 RAM USB Hub. The cost is around $95. MPGrimm2 has recorded several videos showing how to change the insert.

See his full post here: Jump Seat Insert Replacement.

Known Issues

Radio Soft Keys for the Heated/Vented Seats and Heated Wheel will not work on 2013 and 2014 trucks (They will be on the screen but will be grayed out).

Radio Soft Keys for the Heated/Vented Seats will be missing on trucks that added factory heated/vented seats.

Settings menu may not reflect correct setting options on 2013 trucks.

Backup Camera button may be missing on 2016 and 2017 trucks. (Camera will work when in reverse, button on radio is missing).

There is no way to factory reset a radio.

Here's also a recently verified Ram radio PNs

* If you are upgrading from a 3.0 or 5.0 radio to an 8.4 (13-17 Harmon or Panasonic, here's a link to the 8.4 conversion thread for details (start at post 1, 2 & 3). You will also need ATC in most instances (13-17 trucks definitely. 18/classic trucks are 50/50. See below).

Just an 'issue' update for those installing the UAQ/UAS radio in their truck...

We had several reports:
See: Gibbs' .HVAC Issues w/UAS upgrade.

& Outback199 's 19Classic w/same issue at post 138.

A lack of 'full' heat after radio install using the previously recommended 13-17 HVAC modules from the earlier Ra3/Ra4 upgrade method. (Blend door not making full travel & jumping from full Hot to full cold only!)

** EDIT: adding ATC option fixed issue on all cases including those where HVAC module swap didn't and allowed 13-17 modules to work **

- Guido2112 's 17 1500 (fixed w/new module)
- Gibbs ' 18 2500 (fixed w/new 18 module)

** Ckleinfeld 's 15 1500 (used mod. didn't work). .See here


We have identified the correct 18 HVAC modules ...

As DeereGuy stated, it appears that on 2018 trucks ...
- 68366552AA = 2014+ 1500 trucks w/8.4 radios (MTC & ATC)
  ie factory 7 speed fan (w/Variable Displacement A/C Compressor)

- 68366553AA = 2013+ 2500/3500 & 2013 1500 trucks w/8.4 radios (ATC)
  ie factory 4 speed fan (w/Sgl speed A/C Compressor)

Here's how Sawz fixed the 2018 USB hub cutout issue on his earlier console.See here.

-------- 1/15/21 Update -------
Possible 2017 Chrysler 200 Dual USB Hub that fits better (minimal sanding) and is reported to work with the UAQ/UAS.
See Post 2767 here.

- P/N: 68283703AA 2017 Chrysler 200 - dual USB with AUX inputs.

Confirmed by Ezyduzit23 post 3094

2017 Laramie longhorn can confirm the Chrysler 200 hub works flawlessly. Used a fruit peeling knife to shave some plastic. Looks nice and neat no gaps!
Thank you Mpgrimm2 for the harness and advice.

Heated/Vented Seat/Wheel radio buttons will not work on 2013 and 2014 trucks.

Well, there go my plans to get one. I really can't live without my wheel mounted audio controls.

You misread that. Just the heated seat/heated wheel functions via the radio's menus. (For now)

Regular wheel buttons/audio buttons still work.

M² Mods.

Ah, thanks for the clarification.

I have 3D printed adapters to use the 2018 Hub in a 13-17 lid with slight dremeling but will fit and look mostly stock.

Are the adapters for the console or the jump seat?

@Mpgrimm2 is correct. I changed the wording to better clarify that know issue.
