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 factory label reads UDM
- the label serial begins with TM9
- the car left the factory 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
Hands-free Bluetooth with audio streaming
USB input for music 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.
Background on the platform itself is published by the official Uconnect site.
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.
- Find the printed label on the housing and read the serial off it - it sits beside the barcode.
- Type it into the form exactly as printed, without spaces.

Typical Ways a Chrysler Uconnect 8.4 UDM Gets Locked
Almost all of the Chrysler Uconnect 8.4 UDM codes we generate follow one of these four events.
New battery, locked radio
A replacement battery - or a flat one after the car stood over winter - cuts power to the radio, and the anti-theft system arms itself the moment power returns.
The seller had no code
Used cars routinely arrive with a locked radio and no code card in the glovebox. The serial number on the unit is all that is needed to recover it.
After electrical work
The repair went fine - the locked radio is just the side effect of the battery being off the car for a while.
A different unit is in the dash now
Replacement radios are the textbook case: every unit has its own code tied to its own serial. Read the serial off the newly fitted radio and order for that one.
The route back to a working radio is the same in every case: serial number in, original code out, in seconds.

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.
- A keypad for the code fills the middle of the screen.
- Tap the four digits of your code in order.
- There is no separate OK button - the radio checks the code on the last tap.
- A correct code clears the lock screen and the audio comes straight back.
If something goes wrong
The screen shows a wait timer
The timer is the radio protecting itself after failed entries - power on, patience, then try again. 30-minute WAIT timer after three wrong codes.
The serial is hiding from you
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.
It is asking for the code a second time
By design, every loss of power resets the anti-theft lock. Battery disconnect or replacement.
Making sure it is the right unit
The differences are easy to miss, so check this before ordering. 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.
Write the code down - the same four digits work for the life of the unit.
