Understanding the R1 EXT NA 3B MY22

The R1 EXT NA 3B MY22 is an original factory-installed infotainment system developed for selected Chrysler vehicles. Built to deliver reliable audio playback and vehicle integration, this unit may also offer Bluetooth connectivity, touchscreen controls, CD/DVD playback, navigation or multimedia support, depending on the specific version.

R1 EXT NA 3B MY22 is the Model Year 2022-specific external-mount Uconnect 4C NAV 8.4 - same form factor as R1 EXT NA but with a 2022 hardware revision (Apple CarPlay wireless, updated processor, FOTA-capable firmware). The "3B" denotes the third hardware revision.

The R1 EXT NA 3B MY22 was installed in various Chrysler models between 2022. It was commonly fitted to vehicles built on the Harman multimedia platform and remains one of the more recognisable factory radios of that period.

Common features on this unit:

AM/FM 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 specification.

Like many factory-installed radios, the R1 EXT NA 3B MY22 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.

Your R1 EXT NA 3B MY22 Serial Number - Where to Look

Every R1 EXT NA 3B MY22 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 the R1 EXT NA 3B MY22: Top of the chassis assembly, behind the screen module. Single-piece removal.

How to reach the number:

  1. Slide the radio out of the dash - most units need a pair of release keys, which cost very little online.
  2. Read the serial from the printed label on the housing, next to or under the barcode.
  3. Type it into the form exactly as printed, with no spaces or dashes.
Format on the label: T0012 or T00BE followed by 9 digits (for example T0012123456789).

  5. On a correct code the radio leaves security mode and plays again.

Common problems

Too many wrong attempts

Wrong codes put the unit into a lockout, and the only fix is to leave it powered and wait. Three wrong codes triggers a 60-minute PLEASE WAIT countdown.

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 assembly, behind the screen module. Single-piece removal.

Why it happened again

Nothing is broken. Any interruption to the 12V supply brings the lock screen back. Loss of 12V power.

Making sure it is the right unit

A few models in this family share the same face, so the label is what settles it. MY22-specific. If your vehicle is a 2021 or earlier 2022 build (built before mid-2021), you have the standard R1 EXT NA, not 3B. The hardware revision is printed on the chassis label - look for "3B" after the part number.

Write the code down - the same four digits work for the life of the unit.

What Owners Usually Ask

The code is generated automatically as soon as the payment goes through, so it appears on screen within seconds and lands in your inbox at the same time. The service runs day and night, so there is no queue and no waiting for office hours.

No. The code for the R1 EXT NA 3B MY22 comes from the radio's own serial number, not from the vehicle identification number. A VIN lookup only works on Renault and Dacia units - for every other make, including this one, the serial from the radio label is what we need.

Usually yes, because the serial is printed on a label on the unit itself rather than shown on screen. Release keys are cheap and the unit only has to come forward far enough to read the label - the wiring can stay connected.

You get your money back. Send us a short video showing the serial number and the code being entered, and we refund the order in full - no argument, no restocking fee.

Pricing depends on the radio family and starts at $9.99. The exact amount for your serial is shown at checkout before you pay anything, so there is never a surprise on the invoice.

No, and any service that claims otherwise is guessing. The serial is the only input the algorithm has - with no serial there is simply nothing to work from.

What You Get

The original code on screen seconds after you pay, emailed to you as well.

Full money-back guarantee if the code does not open your radio.

Available 24/7 - no booking, no dealer visit, no towing.

Works every time - the code stays valid for the life of the radio.
