5th Gen 2019+ 12" UAX Owners Radio Reboot Issues/info

[Mpgrimm2]

12" UAX radio owners please post/reply back with your truck info/observations similar to what I have done below.


** If you don't have this radio please refrain from posting - we understood those that are glad they didn't get this radio **


Like others that picked up a 5th gen Bighorn, Laramie, Limited with the 12" UAX radio by Panasonic, I have found myself with a frequently rebooting radio after 4 months & 4500 miles on the truck.
(I drive 70+ miles a day for work, so it's happens 2-3 times each way now. Radio is fantastic when it worked up to this point).

I've got a trip to the dealer this week but already know the answer is that there's a sw update supposedly coming out in April that fixes it... Which we know from the 2018 4th gen UAQ/UAS radio could actually be 1.5 - 2yrs to get an update. Just want to get it documented.

My truck info :

- 5th Gen 2019 Ram 1500 Laramie
- 12" UAX radio
- HW PN: CNSC29NFGL
- Application Version: v 33.3.0
(USA-SBX-12.1-LR-33.3.0-20191203-LORM)

My observations:

- Sirius XM radio almost always cuts out first, sometimes for a few minutes before the radio reboots.

- Will get a message: "SXM radio is unavailable" and SXM button is grayed out.

- Often some portion of the screen will go blank before the Reboot if running the split screen... Usually the media/SXM card

- Doesn't matter what audio/media option is playing before the Reboot. ...
SXM, Android Auto/ie Pandora app, fm radio, USB drive, etc.

- Doesn't matter if anything is plugged into the usb hub/ports, ie ... Phone (AA on GS9), USB drive.
(I've made drives with nothing plugged in)

- Doesn't matter if I disable ALL SXM NOTIFICATIONS as some have suggested on other Panasonic 8.4 that do this.


** I do believe that the issue is related to the SXM/Satellite module (SDARS) which faults out and causes the Reboot. Specifically...

>> If I go into DEALER MENU when SXM is working, you can see that the Following info is populated....
- SDAR hardware version: 01-00-01
- SDAR firmware version: 11-46-00
- SDAR Audio/Traffic/Data on Demand: TN647D8H

>> When I check this screen after it faults out/reboots ... SXM is greyed out & " Unavailable" it doesn't show any SDARS info (Just blanks):
- SDAR hardware version:
- SDAR firmware version:
- SDAR Audio/Traffic/Data on Demand:


** To access DEALER MENU : hold the 2 Lower, Outside App Icons at the bottom of the screen for 6-10 secs **
