To my fellow Chrysler Pacifica Owners,
I've attached the Files for North American, US/CN
Chrysler Pacifica with Uconnect 4 8.4" screen require to fully update your Audio Units to the (at this time) current Software Version 40.1 Per Chrysler TSB: 08-076-23
They are organized into separate folders For US/CN (UAV/UCV); and VRM is separate.
Currently I have only the 40.1 Update for our Canadian Friends, when I get ahold of the 28.3 file, I will upload it and update this post
I've now ALSO included the VRM (Video Routing Module) Software Update Per TSB 08-018-21 REV A.
Please note: It is currently unknown if this update works for Canadian vehicles. If someone tries it and is successful, please let me know so that I can update the information accordingly.
At the bottom I've attached photos showing which ports to use for each Update thanks to @ThisSuckersElectrical
for taking the time to take, mark and post these photos for everyone to use as a reference.
Please Follow the Instructions carefully when creating the USB Stick per the TSB.
I will also recommend, as with ALL software programming and Updating, regardless of what module on a vehicle...
Ensure your vehicle battery is properly charged BEFORE attempting the updates,
hook up a battery charger of at least 10A, preferably 20A to ensure battery voltage is maintained.
set my key position to the 'Acc'
position during updates instead of the 'Run'
position, this allows the audio unit and USB ports to power up, but not wasting energy on the rest of the vehicle while updating.
the files being provided DO NOT
include any MAP specific updates, that's a problem for you to sort, do NOT link MAP specific updates here please to keep this thread clean and specific to the actual SOFTWARE Update.
4a) Perform these updates at >> YOUR OWN RISK << As with ANY software update, things CAN happen. If you follow the instructions in the TSB, and have a battery charger hooked up (preferable option) you SHOULDN'T have any issues.
4b) As far as I know, these files are for US Market Pacifica's. I do no know, nor do I guarantee that these updates work on vehicle outside of the US market.
If you try it on a NON-US Market Pacifica, do so at YOUR OWN RISK.
5) If you feel uncomfortable performing these updates, DON'T. Go to your Dealer, if they are no help, try asking Chrysler Cares for Help. They have been FANTASTIC at helping multiple owners to have audio update issues resolved.
6a) SPECIAL NOTE REGARDING Specifically the VRM UPDATE: If you're like me, and had REALLY old VRM Firmware (mine was 17.xx) The update will automatically run TWICE, once to get you to 19.xx, and then run again to update to 2114.12.
6b) Do not unplug your USB stick until it's fully updated, and the units return to the 'HOME' screen. At first it will say updates completed, going to sleep. (it's actually rebooting) Then you'll see the Chrysler Splash screen, after a long first load you'll get to the home screen. THEN, you can remove the USB stick. (I'd probably suggest you double check software version under the setting menu through the REAR screens to verify first)
6c) The upgrade option will pop up on both screens, and it does not matter which screen you Start the process from, But note during the update, ONLY the left (driver's screen) will show progress. Passenger screen will not come back on until FINAL reboot when the Chrysler Splash screen comes up.
7) The VRM TSB has incomplete instructions to create the USB stick, but it is the same as the Uconnect update. Extract files to the base USB drive, not in a folder, and the USB stick MUST be FAT32 File format.
8) This is a suggestion, take it as you will.. I am not a fan of unplugging live modules... that's how you brick things.
a) Turn on Vehicle completely (as tsb states)
b) Remove all dvd's, usbs, chargers, etc etc.
c) After rear screens fully booted up to the 'HOME' screen, Plug in usb into USB port next to BlueRay Player (per TSB)
d) Rear screens will pop up showing update, Click upgrade (again, doesn't matter which screen), and let it do it's thing.
Update Port for UCONNECT UPDATE ONLY
Update Port for VRM UPDATE ONLY
After Update(s) have been completed notes worth mentioning:
After you final update is complete and the Audio unit reboots, and you verify everything updated and versions are correct, I'd suggest leaving the vehicle on for about another 10-15 min. You'll notice many of your apps will initially be unavailable.
After the audio unit does it's reboot, you'll notice on the bottom left corner, in smaller print, the audio unit will start installing all of your apps in the background. I, would suggest letting all of those complete so there's no issues in the future. The TSB doesn't mention anything about it, but as a precaution, I'd go ahead and let all of them install in one swing so your next drive is good and ready to go
