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*
Apple CarPlay and Android Auto*
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.
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:
- Slide the radio out of the dash - most units need a pair of release keys, which cost very little online.
- Read the serial from the printed label on the housing, beside the barcode.
- Type it into the form exactly as printed, with no spaces or dashes.

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.
- The screen shows a numeric keypad for the four digits.
- Tap the four digits of your code in order.
- Verification happens by itself once the fourth digit is in.
- A correct code clears the lock screen and the audio comes straight back.
Things that can catch you out
The radio is counting down
After a few wrong entries the radio stops accepting codes for a while - cutting power only restarts the clock. 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
Nothing on the car's menus shows it - the number lives on the radio's own label. 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
Close relatives of this unit look almost identical from the driver's seat. 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.
The code belongs to the radio and never changes, so keep it somewhere safe once you have it.
