RA4 vs UAQ

[Atcer2018]

Hard to say. I don't know what year they started putting the newer generation in Jeeps. I can say if it has Apple Carplay and/or Android Auto it is the newer Panasonic radio with better resolution.

To be clear, an older generation 8.4 will work in newer trucks too so without knowing the specific features or model number, I couldn't say.

Thank you. It does have CarPlay. Just surprised me that it was a radio out of a 2016. They are nice radios for sure although the replacement looks slightly different and does sound different. The old one had better highs and less bass. I do have the Mopar performance/Kicker speaker upgrade and a Kicker Key amp so adjusting the sound was an easy fix.

I put a UAV from a Grand Cherokee in My 2016 Ram and it has been flawless.

Not saying it won't work well, only that there may be reasons to choose one over the other. Your first hand experience being one of those reasons...

I've found the firmware versions on these can greatly effect the audio quality. I recently reverted my 2018 UAQ from 39.6 to 39.5 to remedy this. Immediately noticeable is the range of the volume knob. I typically listen to music at 24, on the 39.6 firmware I could go all the way to 40 and not be satisfied with the level. It also was difficult to hear all of the instruments until volume levels 30+ on 39.6.

All this to say a firmware upgrade might be in order but can result in bricks so flash at your own risk and try to find the most suitable version first.

Also, I don't have the Kicker Key so it might make all of what I just said needless. It is the last upgrade I plan to do audio wise (eventually)...

Thank you for sharing the knowledge. I had no idea about firmware effecting sound quality. The replacement radio is definitely less “loud” at the equivalent volume setting than the original but with the key amp it’s compensated and given I’m using line level inputs it’s good enough for my 58 year old ears. Mom warned me decades ago about listening to loud music but I didn’t listen. Thanks for the advice about possibly bricking the radio if I change the firmware, I’ll keep what I have.

The UAQ and UAS delamination issues is across the Chrysler umbrella starting with the 2017 Chrysler 300 then then to Dodge/Jeep from 2018 until 2020. LG has since fixed the problem and the 2nd generation U's do not have the delamination issue. Be careful with the dealers replacing with anything but the 2nd generation screens and digitilizers. They will delaminate like they are prone to do.

And how do you know if the replacement is the 2nd generation, when they replace the UAS in your truck?

You'd have to physically disassemble the radio to confirm the revised screen assembly part number.

Yikes, Ok, not what I was hoping to find out. I will just have to pray that is what they installed.
Thanks for the Information...
