Do You Have the Chrysler Uconnect 8.4 UDM?
Before ordering a radio code it is important to confirm the exact model. Compare the design, controls, display and features below with the unit in your dashboard.
What the Chrysler Uconnect 8.4 UDM looks like:
- 8.4" touchscreen in the centre of the dash
- No navigation tile on the home screen - no maps installed
- Built for the Mexico market
- Sales code UDM on the chassis label
- Serial number starting with TM9
You most likely have the Chrysler Uconnect 8.4 UDM if:
- the chassis label carries the UDM sales code
- the serial on the label starts with TM9
- the vehicle was built between 2017-2020
- the screen is the 8.4" touchscreen fitted to the Uconnect 8.4
UDM defaults to Mexican Spanish on boot. If your screen boots in US English by default, you probably have UAQ (US) instead. UDM sits between UDQ and UDV in feature set.
Chrysler Uconnect 8.4 UDM Overview
The Chrysler Uconnect 8.4 UDM is a factory-fitted Chrysler audio and multimedia unit. Alongside standard radio and audio playback it may include touchscreen controls, Bluetooth, CD/DVD playback or factory navigation, depending on how the vehicle left the factory.
Uconnect 8.4 UDM is the Mexican-market Panasonic 8.4-inch mid-spec head unit (the "D" middle letter denotes Mexico/LATAM). Mexican Spanish UI by default, mid-tier feature set between UDQ (basic non-nav) and UDV (nav).
Chrysler used the Chrysler Uconnect 8.4 UDM on selected models produced between 2017-2020, typically alongside the Panasonic multimedia platform. It is one of the factory units most often seen from that era.
Typical features include:
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 UDM is protected by 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.
Reading the Chrysler Uconnect 8.4 UDM Chassis Label
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 chassis label of the unit itself, not in the vehicle documents.
On this unit: Chassis top, white printed sticker. Pull the radio with three 7mm bolts.
Getting to the label:
- Ease 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, beside the barcode.
- Type it into the form exactly as printed, without spaces.

Entering the code on the Chrysler Uconnect 8.4 UDM
It takes under a minute once you have the four digits.
- Turn the ignition on so the radio powers up and shows the locked screen.
- The screen shows a numeric keypad for the four digits.
- Key in the code, one digit at a time, left to right.
- There is no separate OK button - the radio checks the code on the last tap.
- On a correct code the radio leaves security mode and plays again.
If something goes wrong
The radio is counting down
After a few wrong entries the radio stops accepting codes for a while - cutting power only restarts the clock. 30-minute WAIT timer after three wrong codes.
I cannot find the serial number
Nothing on the car's menus shows it - the number lives on the radio's own label. Chassis top, white printed sticker. Pull the radio with three 7mm bolts.
Why it happened again
Nothing is broken. Any interruption to the 12V supply brings the lock screen back. Battery disconnect or replacement.
I am not sure I have the right variant
A few models in this family share the same face, so the label is what settles it. UDM defaults to Mexican Spanish on boot. If your screen boots in US English by default, you probably have UAQ (US) instead. UDM sits between UDQ and UDV in feature set.
Save the code: it stays valid, so the next battery change costs you nothing.
