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

... what did InfoT have to say about it?
(Did you get the radio from them also?)

Well that radio didn’t fix my issue. I’m at a loss now not sure where to go from here.

So update I got in contact with infotainment and I’m getting a new harness. Which I don’t have high hopes for. As for now I have the radio connected like it would be from the factory. I still have steering wheel control and my climate control works when connected like this. Only functions I don’t have are the heated/vented seats and heated steering wheel. Has anyone found a way to wire or bypass this to make it where I don’t have to use the infotainment harness? I don’t have the push buttons on the bottom because I have the aux up fitter switches instead. Any help would be much appreciated.

Long time lurker but recently deal with Mike - @Mpgrimm2 and my 2013 3500 truck had a factory 8.4. Wanted AA so got a harness and radio from Mike. Support is well worth it and the packaging was top notch. Solid guy and actually tests everything first. I got a "new" radio and Mike spent some time and money to make it ship safely and securely. the packaging was on point. For something this expensive that is VERY nice!
So far the only issue I have is the Chrysler 200 hub won't fit all the way in on my jump seat. Mine apparently has a different metal bracket than most that gets in the way. Haven't cut it out as of yet. Pic attached if anyone has a jump seat, check that metal first.
I must say screen is more crisp and audio seems WAY better (more bass) than my factory Harmon unit. Maybe more power to the amp? Maybe placebo.. Not sure. This isn't a cheap upgrade. But absolutely worth it and I'm very glad I met and got to support Mike in what he does.

Converting an '18 classic 2500 tradesman with the stock 5" screen 4 speed blower fan. I'm not too tech savvy, I know just enough to be dangerous...

I can't say enough good things about @Mpgrimm2. I bought a 8.4" radio with AA/dual zone bezel locally on Craigslist for $100, the wiring harness and blower components from mpgrimm2. Turns out the radio was a dud, he talked me though some simple diagnostic ideas via email and over the phone, before I ultimately bought an 8.4 AA unit from him. He was amazing to deal with and instructions for installing the wiring harness were clear and easy to follow.

He let me know of the possible blend door issue with the radio and how to solve it w/ an extra dongle he sells and Alpha OBD. Sure enough, my blend door was acting wonky, for anyone interested, I found a work around for it w/o having to use AlphaOBD.

My blend door lever goes all the way down when I press max a/c.
When the a/c is off, and I start at 'hottest' temp, lever only goes about 75% of the way down when I press the soft or hard key long enough for the temp slider on the radio to get all the way down. I have to press the soft or hard key another 8-10 times to get the blend door to go all the way down.
I can't say it will work for you, but worked on my truck

@Mpgrimm2 send me a pm I’m looking to upgrade my 14 8.4 to a UAQ. If you sell them I’m interested. Thanks

I just upgraded my 2016 Ram 1500 Big Horn from RA4 with Navigation to a new UAS with CarPlay/AA. I found a YouTube video of someone doing the install and then made my way to this forum. I spent a few days reading the hundreds of posts and making notes on how to do the upgrade, and I would like to thank everyone here for all their knowledge and support. I'd particularly like to thank @Mpgrimm2 for his help sourcing my UAS, hub, and harness. He answered the many questions I still had remaining and even helped me get what I needed to upgrade my RA4 from v16.09.09 to v18.45.01.

I'll list my upgrade parts, experience, and notes from the install:

2016 Ram 1500 Big Horn 4x4 Crew Cab 5.7L with: 8.4 Uconnect with Navigation (PN 68258671AH software version 16.09.09), full center console, Alpine sound system, satellite radio, factory HVAC 7-speed fan, Dual zone climate control, factory backup camera (tailgate), heated seats & steering wheel, steering wheel controls with hands-free calling, voice, and radio function.

UAS: PN 68331635AO (April 2023)
Hub: 2017/18 Premium 8pin Chrysler 200 Dual USB Hub (PN 68283703AA)
Adapter harness from @Mpgrimm2

I wanted everything to be plug-and-play and not lose any functionality, so @Mpgrimm2 sourced me the perfect parts and shipped them all quickly. The HU swap was very simple. The backup camera, heated seats, and steering wheel functions didn't function at first, but as others have mentioned, I just had to let the BCM do its thing overnight.

My check engine light came on after everything was installed and went away within a day, someone mentioned this is due to reconnecting the battery to test the newly installed unit while some of the plugs from the dash while still disconnected that throws an error, but quickly resets after a few cycles.

The media hub install went smoothly; I have a full center console, so accessing the media hub harness was simple, with the removal of only 7 T20 Torx screws. There was very little trimming needed to fit the Chrysler 200 media hub, I used an exacto knife - the plastic is pretty soft. As a note, I trimmed only the bottom of the opening because I wanted to retain the top "slot" that was there, but I would suggest trimming the top or both. By trimming only the bottom of the opening, the new hub fit fine and clipped in, but it made it sit too low on the console supports underneath, causing my console tray not to be reinstalled properly and my latch not to close smoothly. I spent most of my time on this install trimming the supporting plastic braces beneath the new media hub so the console tray would fit flush again and close and latch easily.

I hope any of this may be helpful to the next person wanting to make this upgrade, I think it's well worth it! Thanks again to everyone who took the time to experiment and post this thread.
