Is This Your R1 EXT NA?
Before requesting a radio code it is important to confirm the exact model. Match the design, controls, display and features below with the unit in your dashboard.
Typical identification features:
- Centre-stack 8.4" touchscreen
- Built for the North America market
- NA printed on the factory label
- Serial number starting with T0012, T00BE
It is the R1 EXT NA when:
- the factory label reads NA
- the serial on the label starts with T0012, T00BE
- the car left the factory between 2018-2022
- the 8.4" touchscreen is the one the R1 EXT family uses
External-mount = screen sits on top of the dash. If your screen is flush in the centre stack, you have R1 INT NA or an older RA4. Model year 2022 specifically uses the R1 EXT NA 3B variant - see the dedicated page if your vehicle is a 2022 build.
Learn More About the R1 EXT NA
The R1 EXT NA 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.
R1 EXT NA is the externally-mounted Uconnect 4C NAV 8.4 head unit for North American markets - 8.4-inch touchscreen on an above-dash bezel. Apple CarPlay, Android Auto, SiriusXM, built-in NA maps.
Chrysler used the R1 EXT NA on selected models produced between 2018-2022, typically alongside the Harman multimedia platform. It is one of the factory units most often seen from that era.
Common features on this unit:
8.4" touchscreen
AM/FM radio
SiriusXM satellite radio*
CarPlay and Android Auto support*
CD playback
AUX and USB input*
Steering wheel control support
Anti-theft security code
*Availability varies with the vehicle configuration.
The R1 EXT NA carries the same anti-theft protection as most factory units. Once power is cut - a flat battery, a battery swap, or the radio being removed - it will ask for the original code before it plays again.
For the manufacturer's own documentation of this platform, see the official Uconnect site.
How to Read the Serial Number Off Your R1 EXT NA
Every R1 EXT NA has a unique serial number, and the unlock code is derived from it. You will find that number on the unit's own label - it is not in the service book and not on the dashboard.
On this unit: Top of the chassis behind the screen module. R1 is removed as a single screen-plus-chassis assembly via four bolts on the dash bracket.
Getting to the label:
- Bring the radio out of its slot; release keys do it in seconds and nothing needs disconnecting.
- Find the white label on the housing and read the serial off it - it sits beside the barcode.
- Type it into the form exactly as printed, with no spaces or dashes.
The sticker that carries the serial
Four Ways a R1 EXT NA Ends Up Locked
The lock screen rarely appears out of nowhere - one of these four situations is behind nearly every locked R1 EXT NA we see.
New battery, locked radio
Any battery work counts as a power cut to the radio. It locks automatically and waits for the original code before playing again.
The car was in the garage
Any repair that touches the 12V supply - even for a few minutes - is enough to bring up the code screen on the next start.
The code card is long gone
The code card that shipped with the car went missing an owner or two ago. That is not a problem - the code is generated from the radio's serial, not from any paperwork.
You swapped the radio itself
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 way out is the same in every case: serial number in, original code out, in seconds.

R1 EXT NA Vehicle Compatibility
| Vehicle Model | Typical Production Years | Notes |
|---|---|---|
| Jeep Wrangler JL, Gladiator JT (USA, nav trims) | 2018-2022 | |
| Jeep Cherokee KL refresh, Compass (USA nav trims) | 2018-2022 | |
| Ram 1500 DT (USA nav trims) | 2018-2022 |
Vehicle compatibility can vary between trims, model years and regional versions. Because the same car could leave the factory with different radios, confirm your unit before placing an order.
Entering the code on the R1 EXT NA
Nothing to install and no tools needed - just 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.
Things that can catch you out
The screen shows a wait timer
The timer is the radio protecting itself after failed entries - power on, patience, then try again. Three wrong codes shows "PLEASE WAIT" for 60 minutes. Power must stay on for the timer to run down.
I cannot find the serial number
It is printed on the housing, so the unit normally has to come forward to read it. Top of the chassis behind the screen module. R1 is removed as a single screen-plus-chassis assembly via four bolts on the dash bracket.
Why it happened again
That is normal - the anti-theft system re-arms every time the unit loses power. Loss of 12V power - battery service, dead battery, or radio removal.
Making sure it is the right unit
The differences are easy to miss, so check this before ordering. External-mount = screen sits on top of the dash. If your screen is flush in the centre stack, you have R1 INT NA or an older RA4. Model year 2022 specifically uses the R1 EXT NA 3B variant - see the dedicated page if your vehicle is a 2022 build.
Write the code down - the same four digits work for the life of the unit.
