What Is the Chrysler Uconnect 8.4 UJM Radio?
Fitted as factory equipment in selected Chrysler models, the Chrysler Uconnect 8.4 UJM handles audio playback and vehicle integration from the factory. Depending on the version, it can also add Bluetooth, touchscreen operation, CD/DVD playback, navigation or wider multimedia support.
Uconnect 8.4 UJM is the right-hand-drive/Rest-of-World Panasonic 8.4-inch mid-spec head unit (the "J" middle letter denotes ROW/RHD). RHD-optimised UI, mid-tier feature set between UJQ and UJV.
Chrysler used the Chrysler Uconnect 8.4 UJM on selected models produced between 2017-2020, typically alongside the Panasonic multimedia platform. It is one of the factory units most often encountered from that era.
Common features on this unit:
8.4" touchscreen
AM/FM radio
Bluetooth hands-free and audio streaming
USB media playback
SiriusXM satellite radio*
Steering wheel control support
Anti-theft security code
*Availability depends on the vehicle configuration.
Like many factory-installed radios, the Chrysler Uconnect 8.4 UJM is secured with an anti-theft system. If power is interrupted after replacing or disconnecting the vehicle battery, the unit may request the original radio code before it can be used again.
Step One: The Serial Number
The code is generated from the radio's own serial number, so that number is the only thing you need before ordering. It is printed on the factory sticker of the unit itself, not in the vehicle documents.
On the Chrysler Uconnect 8.4 UJM: Top of the chassis label. Pull the radio.
Getting to the label:
- Slide the radio out of the dash - most units need a pair of release keys, which cost a few dollars online.
- Read the serial from the factory sticker on the housing, next to or under the barcode.
- Type it into the form exactly as printed, without spaces.

Once the code arrives
Nothing to install and no tools needed - just the four digits.
- Switch the ignition on and let the radio boot to its security screen.
- A keypad for the code fills the middle of the screen.
- Enter the four digits in the order you received them.
- Verification happens by itself once the fourth digit is in.
- On a correct code the radio leaves security mode and plays again.
Common problems
The screen shows a wait timer
After a few wrong entries the radio stops accepting codes for a while - cutting power only restarts the clock. 30-minute WAIT after three wrong codes.
The label is not where I expected
It is printed on the housing, so the unit normally has to come forward to read it. Top of the chassis label. Pull the radio.
Why it happened again
Expected behaviour: the security system trips again whenever power is cut. Battery service.
I am not sure I have the right variant
The differences are easy to miss, so check this before ordering. UJM is RHD mid-spec. If your steering wheel is on the left, you do not have UJM - check the UA-/UC-/UD-/UG- pages instead.
Write the code down - the same four digits work for the life of the unit.
