Understanding the Radio Serial Number and How to Locate It on 2019 300

The initial step is to find the radio's serial number.

Based on the head unit type fitted in your 2019 300, the S/N can usually be accessed either through the display menu or by checking the label on the radio itself.

Follow the steps below to identify your serial the right way.

2019 Chrysler 300 - Which Radio Did You Get?

The 2019 Chrysler 300 keeps the same Uconnect 4 line-up as 2018. Three head units across the trim range, separated by screen size and built-in GPS navigation.

  • Uconnect 4 (UAG) - 7-inch non-NAV touchscreen. Standard on the entry 300 Touring trim. Visual ID: 7-inch display centred in the dash bezel opening; Apple CarPlay and Android Auto are supported, but there is no factory NAV app or Map tile on the home screen.
  • Uconnect 4C (UAS) - 8.4-inch non-NAV touchscreen. Common on Touring L and 300S without the navigation upgrade. Visual ID: large 8.4-inch screen filling the dash opening edge to edge, CarPlay and Android Auto present, but no Map/NAV tile because GPS navigation is not built in.
  • Uconnect 4C NAV (UAQ) - 8.4-inch touchscreen with built-in GPS. Standard on 300C and 300S Premium, optional on lower trims. Visual ID: same 8.4-inch bezel and glass as UAS, but the home screen carries a dedicated NAV/Map tile and on-board maps work without a phone.

Quick test: 7-inch screen = UAG, 8.4-inch without a Map tile = UAS, 8.4-inch with a Map tile = UAQ.

View Your Serial on the Radio Display

These are the steps you should follow for 2019 Chrysler 300:

The 2019 Chrysler 300 — the final generation of Chrysler's full-size rear-wheel-drive sedan — comes with the Uconnect 4C (RA4) with an 8.4" touchscreen. Dealer Mode works differently from older RA3 models: press the bottom-left and bottom-right corners of the physical screen bezel frame simultaneously for 5 seconds (ignition ACC or ON). Dealer Mode opens. Navigate to: System Info → Radio Part Info → Serial Number.

Display-Based Serial Number Retrieval

The 2019 Chrysler 300 continues with the Uconnect 4 family - 8.4-inch UAQ NAV, 8.4-inch UAS non-NAV, and the smaller 7-inch UAG. On these units the head-unit serial number can normally be read on screen via the hidden dealer/diagnostic menu, although some 2019 builds had dealer mode tightened by a software update.

Uconnect 4C 8.4 (UAQ / UAS)

  • Switch the ignition to RUN/ACC and wait for the Uconnect interface to finish booting.
  • Press and hold the driver-side temperature UP, the driver-side temperature DOWN, and the front DEFROST buttons together for roughly 5-10 seconds.
  • If the climate-button shortcut does nothing on a software-updated unit, press and hold the bottom-left and bottom-right corners of the screen at the same time for about 5-10 seconds.
  • Browse to the radio/system info section to view the 14-character serial number printed on screen.
  • Photograph the screen before transcribing the characters.

Uconnect 4 7-inch (UAG)

  • Place the ignition in RUN/ACC and let the screen finish loading.
  • Press and hold the temperature UP and temperature DOWN buttons together for around 5-10 seconds to open the engineering menu.
  • Open System Info / Target Main Data and read the serial number on screen.
  • Take a photo of the display so each character can be copied accurately.

Serial Number on the Unit

If the serial does not appear on display, the next step is checking the radio itself.

Many Chrysler radios require physical access to the serial tag attached to the unit.

Usual approach:

  1. Start by completely shutting off the engine - pull the key out.
  2. Then detach the radio surround.
  3. Next, unscrew the mounting points and move the radio forward.
  4. Look for a factory sticker showing the serial number.

If Dealer Mode is unavailable on the 2019 Chrysler 300, remove the RA4 unit from the 300's center stack. The bezel corner press sometimes fails after OTA firmware updates.

  1. Remove the center stack trim with a plastic trim tool.
  2. Remove the four Torx T20 mounting screws.
  3. Pull the unit forward to access the serial label on the side or back of the chassis.

View Serial by Pulling Out the Radio Unit

If dealer mode has been disabled on a 2019 Chrysler 300 by a Uconnect software update, the printed chassis label remains the next reliable source. The Uconnect 4 head unit on the LD-platform 300 sits in a centre stack closely tied to the climate cluster, so work slowly and methodically.

  • Safety first: turn the ignition off, remove the key, disconnect the negative battery terminal, and wait a few minutes before touching wiring; never disturb the yellow airbag/SRS connectors and use plastic trim tools to avoid shorts and broken clips.
  • Tools you will need: plastic trim removal kit (a Mopar C-4755 trim stick or equivalent), Phillips and small Torx bit set, 7mm/10mm socket set, flashlight.
  • Pop the centre instrument panel bezel free using a plastic pry tool, starting at the lower edge and working up the sides; on the LD 300 this bezel also carries climate and clock connectors, so keep finger pressure even.
  • Unclip the A/C-heater control and clock harnesses at the rear of the bezel, then set the trim aside on a clean cloth.
  • Remove the mounting fasteners (typically four screws, two upper and two lower) holding the radio cage to the dash support bracket.
  • Slide the radio rearward and disconnect the antenna lead and the multi-pin power/data harness.
  • The serial number sits on a printed barcode/sticker label on the top or side of the radio chassis, next to the part number and supplier markings.
  • Photograph the label and double-check ambiguous characters such as 0/O, 1/I and B/8 before submitting the serial. If you are not comfortable working around airbag wiring or the integrated climate cluster, have a professional installer remove the unit for you.

Common S/N Formats Used on 2019 300 Units

Year Chrysler 300 RA4 serial patterns:

  • T00AM – Harman RA4 Uconnect 4C (primary format on the 300)
  • T00BE – Continental variant

Serial is 14 alphanumeric characters. Skip the part number (starts with P or 68).

Common S/N Formats Used on 2019 Chrysler 300 Units

The factory radios fitted to the 2019 Chrysler 300 use the standard Mopar/Uconnect serial style. The exact prefix depends on which Uconnect tier shipped with the car and which supplier (Visteon, Continental, Harman or Panasonic) built the unit.

Uconnect 4C 8.4 (UAQ / UAS)

  • Typically printed as a 14-character alphanumeric string on the chassis label.
  • Commonly begins with T - frequent prefixes include T00AM, TM9 and TQ1 - or with A2C on Continental-built variants.
  • Usually a continuous run of letters and digits with no spaces or dashes.

Uconnect 4 7-inch (UAG)

  • Usually carries a Mopar/Harman or Panasonic-style serial printed on the chassis sticker, so use the label on the unit itself as the reference.
  • Copy the serial exactly as printed and avoid guessing characters that look unclear.

Locked 300 Radio? Here's Exactly How to Get the Code

Getting your radio code takes only 4 easy steps.

  1. Locate the radio's serial - this is the only information required by our side.
    Unlike dealership lookup, no VIN or paperwork is needed.
  2. When you've found the S/N, type it into the form above.
    The system checks it against a database of supported factory radios and automatically retrieves the matching radio code.
  3. In most cases, the code will appear instantly on the screen after payment and is also sent to your email for backup.
    If manual verification is required (rare situations), you'll be notified before checkout.
  4. When you receive it, just enter it into the radio to restore full functionality.

How to Enter the Radio Code

Now that you've generated 2019 Chrysler 300 anti-theft code from the serial, you're ready to reactivate the radio.

Many drivers hesitate at this stage because input process can look different across radio versions, but it's usually quick.

When the radio shows ENTER CODE, it means the unit is waiting for the correct numbers.

Detailed Input Instructions for 300 2019

To enter the code on the 2019 Chrysler 300 Uconnect 4C:

  1. Turn ignition to ON. Screen shows "ENTER CODE".
  2. Tap each digit of your 4-digit code on the touchscreen keypad.
  3. Radio auto-confirms after the 4th digit. No confirm button needed.

3 wrong attempts cause a 60-minute lockout. Keep ignition ON. Turning off restarts the timer.

Correct Entering Process

Once the unlock code has been retrieved for a 2019 Chrysler 300 Uconnect head unit, it can be entered straight at the dash - no scan tool or dealer visit required.

  • Limited attempts: Mopar/Uconnect head units only accept three incorrect tries before the radio enters a WAIT state, so confirm every digit before pressing it.
  • Turn the ignition to RUN/ACC so the radio powers up while the engine stays off.
  • Wait for the display to show CODE, Please enter Anti-Theft Code, or a similar prompt.
  • On the Uconnect 4C 8.4 (UAQ/UAS), key the digits using the on-screen number pad and confirm with the OK/Enter touch button.
  • On the Uconnect 4 7-inch (UAG), press the numbered preset buttons in sequence (preset 1 for the first digit, preset 2 for the second, and so on) - or use the on-screen keypad if the unit prompts for it.
  • If WAIT appears after wrong attempts, leave the ignition in RUN with the radio powered for a continuous 30 minutes (the vehicle may be driven during this time) before trying the correct code again.

Why Is the Radio Asking for a Code?

The 2019 Chrysler 300 RA4 self-locks after power is cut. The final-gen 300 uses the same anti-theft system — a disconnected radio won't work without the code.

Most common trigger: battery replacement or disconnect. Other causes:

  • Failed fuse after electrical work
  • Buying the 300 used without a known code
  • Battery disconnect during service
  • Battery drained from storage

Code comes from the radio serial number — not the VIN.

Fixing Common Code Entry Problems for 2019 300

The radio label: serial = 14 alphanumeric chars starting with T00AM or T00BE. Part number starts with P or 68 — skip this.

If the 300 screen boots normally, anti-theft is inactive. Trigger it: briefly disconnect the battery, reconnect, turn ignition to ON.

3 wrong entries lock the 300 RA4 for 60 minutes. Keep ignition in ON or ACC. Cutting power restarts the timer from zero.

The 300 RA4 label carries both serial and part number. Serial: 14 chars starting with T00AM or T00BE. Part number (skip): starts with P or 68.

If you read from the screen, verify against the physical label. Screen glare on the 8.4" can cause misreads. Contact support for a free re-check if needed.

The 300 Uconnect 4C uses touchscreen-only code entry. Press each digit directly on the on-screen keypad. No physical buttons needed. Auto-unlocks after the 4th digit.
