2022 Ram 2500 Head Units We Cover
Every card below opens a radio model that shipped in the 2022 Ram 2500. Compare the screen size and faceplate to pick the right one, then check where the serial is printed.
How Our Radio Code Generator Works for 2022 Ram 2500
Vehicle radios use security codes tied to the radio unit itself instead of the model or production year.
- The system uses the 2500's radio serial to retrieve the unlock code.
- When you input the serial into the generator, the system identifies the radio unit and retrieves the corresponding code.
- You can then enter the code directly into your Ram radio.
- Compared to Ram dealer retrieval, this method is faster and more convenient.
How Serial Numbers Work and Where to Find Them on 2022 Ram 2500 Radios
The starting step is finding the radio serial number.
Many drivers assume the code depends on the Ram model or year, but in reality, the whole process depends on the unique radio unit's serial number.
This number identifies the exact head unit installed in your Ram 2500.
This is actually better, because if you have a used radio, the VIN or other Ram-specific data wouldn't help.
Based on the radio version used, you can retrieve the serial directly from the screen or by checking the label on the radio chassis.
Radios Offered in the 2022 Ram 2500
For 2022 the Ram 2500 runs the Uconnect 5 infotainment platform as standard across SLT and above (with Uconnect 4 retained on the very base Tradesman/base Chassis Cab in some markets). Uconnect 5 introduced wireless Apple CarPlay and Android Auto, five user profiles and a much faster processor compared with the Uconnect 4 hardware it replaced.
- Uconnect 3 / Uconnect 4 (sales code
UAG) - 5-inch base touchscreen, retained on the lowest Tradesman/base Chassis Cab build only. Visual ID: small 5-inch screen with conventional climate controls below. - Uconnect 5 with 8.4-inch display (sales code
UBL) - 8.4-inch landscape touchscreen with wireless Apple CarPlay and Android Auto, optional GPS navigation. Visual ID: 8.4-inch glass with the Uconnect 5 home grid (multiple user profiles, large widgets) instead of the older Uconnect 4 tile layout. - Uconnect 5 NAV with 12-inch display (sales code
UBQ) - 12-inch portrait touchscreen with built-in GPS, wireless Apple CarPlay and Android Auto. Standard on Limited and optional/standard on Laramie depending on the build. Visual ID: large vertical 12-inch glass with split-screen and the Uconnect 5 interface.
Quick test for 2022: a 5-inch screen with the older Uconnect interface means UAG, an 8.4-inch landscape screen with the new Uconnect 5 home grid means UBL, and a tall 12-inch portrait screen running Uconnect 5 means UBQ.
Access the S/N on the Radio Display
These are the steps you need to follow for 2022 Ram 2500:
The 2022 Ram 2500 HD work truck is equipped with the Uconnect 4C (RA4) 8.4" touchscreen in the HD's center stack. The serial number is retrievable via Dealer Mode:
- Turn ignition to ACC or ON.
- Press the bottom-left and bottom-right corners of the physical screen bezel (plastic frame, not glass) at the same time for about 5 seconds.
- Dealer Mode opens on the display.
- Go to: System Info → Radio Part Info → Serial Number.
Note On some 2022 Ram 2500 units, Dealer Mode may be restricted after a software update. If the bezel press fails, physical radio removal is the fallback.
Releasing the Unit to View the S/N on the Tag
If the serial number cannot be accessed via display, use the hardware method.
Most Ram 2500 OEM radios include a label with the serial number printed on the chassis.
Basic process:
- Disable power.
- Lift away surrounding mounting frame.
- Loosen screws holding the radio.
- Move slightly to inspect the label.
If Dealer Mode is unavailable on your 2022 Ram 2500, the RA4 radio must be removed to access the serial label:
- Turn off the vehicle.
- Remove the surrounding trim panel using a plastic pry tool. The 2500 HD's center stack may have more robust trim pieces than the 1500. Apply even pressure to release the friction clips.
- Unscrew the mounting screws (Torx T20 or T25) securing the radio.
- Slide the unit forward to read the serial label on the side or top of the chassis.
Cables don't need to be unplugged while you photograph the serial.
Releasing the Unit to Access the S/N on the Tag
The factory radio in the 2022 Ram 2500 also carries a printed barcode/sticker label on the chassis. On the fifth-generation DT HD dash the head unit (especially the 12-inch portrait UAX/UBQ) sits inside a wide centre-stack bezel that integrates the screen surround with adjacent climate and storage trim, so the work needs to be done methodically.
- Safety first: turn the ignition fully off, remove the key fob from the cabin, disconnect the negative battery terminal and wait at least 10-15 minutes before touching wiring so the SRS/airbag capacitors can discharge. Avoid yellow airbag/SRS connectors entirely and use plastic trim tools so nothing shorts or breaks.
- Tools you will need: plastic trim/panel removal kit, T20 Torx bit, Phillips #2 screwdriver, 7mm socket and short extension, flashlight, clean microfibre to rest the bezel on.
- Removal overview (2022 Ram 2500 dash): lift the rubber beauty pad on top of the centre stack to expose two T20 Torx screws and remove them; lift the rubber mat in the small cubby behind the 120V outlet to expose a third T20 Torx screw and remove that as well. With those three screws out, pull the centre-stack bezel rearward starting at the lower edge to release the spring clips around its perimeter. The bezel carries the hazard/HVAC switches, so unclip those harnesses before setting it aside on a clean cloth. Remove the four 7mm screws securing the radio cage to the dash support bracket, then slide the head unit straight rearward and disconnect the antenna lead and the multi-pin power/data connectors at the rear.
- Where the serial sits: the serial number is printed on a barcode/sticker label on the top or one side of the radio chassis, alongside the part number and supplier markings. Photograph the label up close and double-check ambiguous characters such as 0/O, 1/I and B/8 before submitting the value.
- Tips and professional advice: the 12-inch UAX/UBQ portrait head unit on the 2500 is deeply integrated into the wider centre-stack trim and shares hardware with the climate cluster, hazard switch and 120V outlet bezel - if the trim resists, stop and double-check for hidden screws rather than pulling harder. Owners who are not comfortable working around airbag wiring or releasing the wide integrated bezel should have a professional installer or dealer technician remove the unit instead; an experienced shop typically completes this in well under an hour.

Common S/N Formats Used on 2022 2500 Units
The 2022 Ram 2500 Uconnect 4C (RA4) serial number formats:
T00AM– Harman Uconnect 4C (standard prefix)T00BE– Continental versionT0MYD– Updated Harman units (later models)
Radio designation: RA4 (Uconnect 4C, 8.4"). Serial: 14 characters alphanumeric. The Ram 2500 HD received the RA4 with the 2019 redesign.
Important Don't confuse the serial with the part number (P05064... or 68...). Only the 14-char serial generates the code.
How Serial Numbers Usually Look on These Ram 2500 Radios
The factory radios fitted to the 2022 Ram 2500 are predominantly Uconnect 5 head units (with Uconnect 4 retained on the base 5-inch UAG only). The serial style follows the standard Mopar/Uconnect convention, with the exact prefix driven by the supplier and software build of the specific unit, so any pattern below should be treated as a guide rather than a strict rule.
Uconnect 5 8.4-inch (UBL) and 12-inch (UBQ)
- Typically a 14-character alphanumeric string printed on the chassis barcode label.
- Often begins with
T(for exampleT00-prefixed Mitsubishi Electric builds) or withA2Con Continental-built modules. - Printed as a continuous run of letters and digits, with no spaces or dashes.
Uconnect 3 / Uconnect 4 5-inch (UAG, base only)
- Usually carries a Mopar/Visteon or Panasonic-style serial on the chassis sticker, so the printed label on the unit itself is the authoritative reference.
- Copy the serial exactly as printed and avoid guessing characters that look unclear.
Entering the Radio Security Code
When you obtain the correct unlock code based on the S/N, you can restore default functionality by entering it into the unit.
The code entry process depends on the control layout, but most 2022 2500 systems follow a similar structure using preset buttons, touch controls, or rotary knobs - depending on if it's a factory or an aftermarket unit.
You will typically see SAFE displayed on screen.
Detailed Entering Instructions for 2500 2022
Entering the unlock code on the 2022 Ram 2500's Uconnect 4C:
- The 8.4" screen presents "ENTER CODE" after a battery event.
- Tap the touchscreen keypad to enter each digit of the 4-digit code.
- The radio restores after the 4th digit – no confirm step needed.
Lockout Warning: 3 wrong attempts = 60-minute lockout. Keep ignition ON. Cycling the ignition restarts the wait. HD work trucks must complete the full wait without interruption.
What Caused the Radio to Lock?
The Ram 2500's Uconnect 4C activates anti-theft after any power interruption. HD Ram 2500 owners encounter this most often because of:
- Battery replacement — primary cause. HD trucks have higher electrical loads, making battery replacements more frequent.
- Fleet service battery swaps — commercial and fleet 2500s undergo regular battery service.
- A failed radio fuse — common after aftermarket work.
- Buying fleet-retired without the code.
The code is derived from the radio's serial number — not the VIN.
Fixing Common Code Entry Problems for 2022 2500
No code prompt means the Uconnect 4C isn't activated. To force the code screen: pull the radio fuse and reinsert it, then turn ignition ON. The prompt appears on startup.
The Ram 2500's Uconnect 4C uses touchscreen-only code entry — press each digit on the virtual number pad. No physical preset buttons are used. The radio auto-unlocks after the 4th digit.
A rejected code on the Ram 2500's Uconnect 4C typically indicates the wrong serial was submitted. The RA4 label has the serial (T00AM, T00BE, or T0MYD, 14 chars) and the part number (P05... or 68...) — the serial alone generates the code.
HD labels may be hard to read. Wipe down the label or photograph it and zoom in. Reach out for a free re-check if needed.
The Ram 2500's Uconnect 4C locks after 3 wrong entries, showing "ENTER CODE" but blocking all input during the lockout.
To reset: Keep ignition ON for a full 60 minutes. Turning off restarts the countdown. Commercial-use 2500s that get turned off frequently must complete the full 60-minute wait in one sitting.
The Uconnect 4C serial on the Ram 2500 is accessible via Dealer Mode (System Info → Radio Part Info → Serial Number) or on the physical label on the unit housing after removal. Serial: 14 chars starting with T00AM, T00BE, or T0MYD.
Ignore the part number (P05... or 68...) on the same label.
