2014 Ram 2500 Radio Code: Retreat It in Seconds

2014 Ram 2500 - Which Radio Did You Get?

The 2014 Ram 2500 carries the same Uconnect head unit family as 2013, with sales codes spanning RA1 through RA4. Most trucks left the factory with one of four possible radios, distinguished by screen size and the presence of a NAV tile.

1. Uconnect 3.0 / RA1 - base AM/FM/CD radio on the lowest fleet-spec Tradesman trims. Small monochrome strip display, hard tuning and volume knobs, no touchscreen and no Bluetooth.
2. Uconnect 5.0 / RA2 - 5-inch colour touchscreen, common on Tradesman and entry SLT. Six soft keys flank the display, no CD slot, no NAV button, supports Bluetooth, USB and an aux input.
3. Uconnect 8.4 / RA3 - 8.4-inch landscape touchscreen, optional on SLT and standard on Laramie. Capacitive shortcut row across the bottom of the screen. No Nav tile on the home screen.
4. Uconnect 8.4N / RA4 - 8.4-inch screen with the navigation database enabled. Optional on most trims and standard on Longhorn. A Nav tile sits on the home screen and a SiriusXM Traffic/Travel Link splash appears at startup.

Quick tell: no screen at all = RA1; 5-inch screen = RA2; 8.4-inch screen with no Nav tile = RA3; 8.4-inch screen with a Nav tile = RA4. Sales code is printed on the label on top of the radio chassis.

Pull the Serial Number From the Touchscreen

If your 2014 Ram 2500 has the 8.4-inch Uconnect, you can usually pull the serial number directly off the screen via a hidden dealer/diagnostic menu - much faster than removing the radio from the dash. The smaller RA1 and RA2 head units do not have a reliably documented on-screen serial readout for this generation.

Uconnect 8.4 (RA3) and Uconnect 8.4N (RA4)

1. Place the ignition in the RUN position so the 8.4-inch touchscreen is fully booted.
2. Press and hold the driver's temperature UP, temperature DOWN and front DEFROST buttons together for around 7 seconds.
3. When the dealer/diagnostic menu opens, select the radio-information entries near the top of the list - they list serial numbers, hardware/software revisions and similar identifiers.
4. Note the full serial exactly as printed, including any letters at the start such as T00AM or TM9.
5. Press Done, or cycle the ignition off/on, to exit the menu.

Uconnect 5.0 (RA2) and Uconnect 3.0 (RA1)

1. An equivalent on-screen serial-number readout for these smaller radios is not consistently documented for the 2014 Ram 2500.
2. If the dealer-mode shortcut does not surface a serial entry, fall back to the chassis-label method described in the removal block.

Removing the Radio to Read the S/N Tag

If the on-screen method is unavailable or the radio is stuck at the CODE prompt, the chassis label is the most reliable source for the serial number on a 2014 Ram 2500.

Safety first

1. Turn the ignition fully off and remove the key.
2. Disconnect the negative terminal of the 12V battery.
3. Wait several minutes before working near the dash so airbag circuits can fully discharge.
4. Stay clear of yellow airbag wiring while removing trim.

Tools to have ready

1. Plastic trim/panel pry tools to release the dash bezel without scratches.
2. A T20 Torx driver for the screws hidden behind the rubber beauty plates at the top of the bezel.
3. A Phillips driver for the two screws inside the lower console cubby (if your truck has the centre floor console).
4. A 7 mm socket or driver for the four radio retaining screws.
5. A phone/camera to photograph the chassis label.

Removal overview

1. At the top of the dash bezel, lift the rubber RAM-branded beauty plate with a fingernail or plastic pick to reveal two T20 Torx screws and back them out.
2. Lift the rubber plate inside the cubby above the centre HVAC vents to reveal a single T20 screw and remove it.
3. If your truck has the centre floor console, lift the rubber pad at the front of the console well and remove the two Phillips screws underneath.
4. Starting at a lower edge, gently pry the dash bezel outward; it is held by retaining clips. Walk the tool around the perimeter to release each clip.
5. Pull the bezel forward and unplug any small switch/HVAC connectors on its back.
6. With the bezel off, undo the four 7 mm screws now visible at the corners of the radio chassis.
7. Slide the head unit out and disconnect the main wiring harness and antenna lead.

Where the serial sits

1. Look for a printed label on the metal chassis - typically on the top or side face.
2. Copy the long alphanumeric string next to the barcode and double-check similar characters (O vs 0, I vs 1).

Tips

1. Photograph the label so the serial is preserved as a permanent reference.
2. Reinstallation is the reverse: harnesses on, four 7 mm screws home, bezel pressed in until clips seat, T20 and Phillips screws restored, then reconnect the battery.

Standard Serial Number Patterns for This Radio

The 2014 Ram 2500 was supplied with several different Uconnect head units, each from a different manufacturer, so the serial-number style depends on which radio is fitted. The patterns below are the ones most often reported for this generation.

Continental-supplied Uconnect 8.4 (RA3 / RA4)

1. Frequently shown with a T00AM prefix followed by a numeric tail, for example a string resembling T00AM1234567.
2. The prefix is printed inline with the rest of the serial on the chassis label.

Panasonic-supplied Uconnect units

1. Often start with TM9 followed by additional digits or letters.
2. This pattern has been widely associated with Panasonic-built Mopar radios from the Uconnect 8.4 era.

Uconnect 5.0 (RA2) and Uconnect 3.0 (RA1) base radios

1. Also carry a printed serial label, but the prefix can vary by supplier batch.
2. Read the full string off the label rather than assume a fixed pattern.

If the alphanumeric you read does not match any of these examples, double-check that you have copied the serial line rather than the part number. The serial is normally the longest string on the label and is the one tied to the barcode.
