Anyone have an issue with no sound from rear speakers after old 8.4 To 8.4 4C UAQ ?

Not on mine, I have a 2017 Ram 1500 and upgraded to a 8.4 with nav from the 5 inch screen and then upgraded it again to the 8.4 UAQ.Anyone have an issue with no sound from rear speakers after old 8.4 To 8.4 4C UAQ ?
If you haven't let it set for a little while after install through several power cycles/hours let that happen first. It should read the BCM and change the display.On a 2013 how do I fix the A/C issues where you can’t control the temperature only high and low
Try pulling the inline fuse for the radio in the engine bay for 15 minutes then plugging back in. Conversely you can do the same with the negative battery cable.It’s been in for 3 months so far
Is this from a 5th gen truck and not a Classic? If so, I'd imagine that is where your issues stem from and this would be a UAV radio.Hello all! After months of lurking and reading 203 pages, I performed the upgrade but am left to ask for help.
4 days ago I performed 8.4 upgrade on my 2015 Ram 1500 Limited (5.7L V8). Original equipment was 8.4” UConnect (no CarPlay obviously). Bought the new 8.4 from a salvage yard which came from a 2020 Ram 1500 Big Horn/Lone Star 5.7L.
Upgraded to:
- 8.4” UAS(Q?) P/N: (P)68428539AC (Aptiv)
- Foruly RAM Media Harness (Amazon)
- UOIENRT Compass USB AUX Port (Amazon)
Install went fine, only hiccup was the connector orientation for the purple fakra didn’t fit in the port, so I swapped the plastic housing from the original and it clicked in fine.
NOW (4 days later) - everything works great with a few exceptions which are critical in my opinion:
1) Backup camera shows black screen with “…camera unavailable”
2) Steering wheel volume/tune controls do not work (everything else does)
3) Outside temp shows Celsius
4) SXM works fine but no SXM app in menu
5) Limited settings options — bought OBDLink MX+ and codes show VIN mismatch, camera disconnect, (B2206-00 and B222C-00) etc.
I’ve tried:
1) Disconnecting battery
2) Removing fuse
3) Parking outdoors overnight
4) Reset to default settings
I’m at a loss! Any guidance???
Thank you in advance!
I’m guessing 5th gen based on grill style from the VIN lookup. My only cause for hope is that I did not have the configuration or mounting issues that everyone seemed to need to modify in the other thread. Ie, the screen mounted perfectly, the UConnect radio I installed did not appear to have any un-used ports after I installed it.Is this from a 5th gen truck and not a Classic?

Does anyone know if it's possible to switch from a early style gen 4 bezel and u connect with nav to the layer gen 4 style bezel and 8.4" UAS u connect ?Adding Some Notes here ....

Get a new (LA084X01 SL03) Screen/Digitizer assembly (definitely not an SL01 version… SL02 maybe) ~ $400 -$500 and replace it yourself
…. Or send it off to United Radio (Peachtree GA) recommendedor NavRepair (FL)

Unfortunately the communication protocols are different from the 2009-2012 trucks and the +2013 trucks and the factory radios are incompatible.Does anyone know if it's possible to switch from a early style gen 4 bezel and u connect with nav to the layer gen 4 style bezel and 8.4" UAS u connect ?
Sometimes, the firmware just has bad sound quality. I have 39.6 for your radio if you'd like to try and flash it?Hey,
I just installed a UAQ in my 2014. Install wise, all went as expected. But those of you with the alpine system, have you noticed a significant drop in audio quality over the RA4? I have read a few posts that said there were some differences but the sound quality on mine (any source, Bluetooth, CarPlay over usb) is absolutely atrocious.
I know the alpine system isn’t amazing by any stretch, but in comparison to the Harman unit, now with the UAQ I have to lower the bass as much as possible, crank the midrange, and the treble is very sibilant regardless of the setting (for reference I measured the response with a calibrated microphone). All I can say is that I almost want to take the UAQ back out and put something else in.
I have tried to do a few checks. All speakers work, balance and fade work, I’ve checked that the truck proxi aligned and sent the eq curve from the bcm to the radio. I am on update
CANADA-ASO-8.4-JR-34.2.0-20200123-JOM2
Just curious what the general consensus is on how these sound?
Shoot me a PM with your Gmail address and I'll send it your way.That would be great if you don’t mind. I am definitely up to attempting to flash it
