How to Find the Serial Number on Your 2019 Dodge Caravan Radio?
The first step is to locate the radio's serial number.
Based on the head unit type fitted in your 2019 Caravan, the serial can be found either through the screen menu or by pulling the unit out and checking the label on the radio itself.
Below are the most common methods to identify your S/N the right way.
2019 Grand Caravan - Which Radio Did You Get?
For 2019 the Grand Caravan still ran the same three-radio fleet that had served the van since 2013 - no Uconnect 8.4 RA3/RA4, no platform refresh. Base RES (Media Center 130) remained the AM/FM/CD non-touchscreen radio with single-line display, hard preset buttons and rotary knobs - standard on SE/SE Plus and the most common fit. RBZ (430 MyGIG) was the volume touchscreen option on SXT and GT: 6.5-inch color touchscreen, glossy black bezel, hard keys for Radio, Media, Controls and More on the sides, and no NAV soft key on the home menu because it has no navigation. RHB (430N MyGIG) was the rare top-tier touchscreen with Garmin navigation - same 6.5-inch bezel as the RBZ but distinguished on-screen by a NAV soft key, the Garmin boot logo, and a 28GB hard drive for ripped music. The optional overhead rear-seat DVD entertainment system - 9-inch flip-down headliner screen with a separate DVD player in the lower dash and wireless headphones - was still available on higher trims and is independent of which head unit you have.
Quick Method: Find the Serial Number on the Screen
Try the following for your 2019 Dodge Caravan:
The 2019 Dodge Caravan is a family minivan and comes with the Uconnect 8.4" (RA3) touchscreen. The serial number can be retrieved directly from the screen using Dealer Mode.
Climate Button Method:
- Turn the ignition to ACC or ON.
- In the Caravan's center stack, the Climate Up, Climate Down, and Front Defrost buttons are located below the 8.4" screen. Press and hold all three at once for 5 seconds.
- Dealer Mode appears on the screen.
- Navigate to: System Info → Radio Part Info → Serial Number.
Alternative: Hold Temperature Up (red) and Temperature Down (blue) for 5 seconds to open Engineering Mode, then follow the same path.
Locate Serial on Caravan's Radio Chassis
If the serial number cannot be accessed through menu, use the removal method.
Most Dodge Caravan factory radios include a label with the serial number printed on the housing.
Step-by-Step Approach:
- Power down the vehicle.
- Lift the trim surrounding the radio.
- Loosen the mounting bolts.
- Slide the unit slightly out to access the label.
The serial number is usually located near the printed code.
If Dealer Mode is inaccessible on your 2019 Caravan, the radio needs to be removed to find the serial label. The Caravan's tall, accessible console makes the process manageable from the front seat:
- Remove the center bezel – The Caravan's bezel covers the 8.4" display and HVAC section. Using a plastic trim tool, work around the perimeter to pop off the friction clips.
- Remove the 4 mounting screws – Torx T20 or Phillips screws at the radio frame corners.
- Pull the radio forward – Slide the unit out to expose the serial label on the top or side unit.
The serial is a 14-character code on a barcode sticker. The wiring harness don't need to be disconnected.
Serial Number on the Unit
The factory head units offered on the 2019 Grand Caravan - typically the RES single-CD radio (standard on most trims), the RBZ MyGIG 430 (6.5-inch touchscreen, available with the Single-DVD Entertainment Group on SE/SXT), the RHB MyGIG 430N (6.5-inch touchscreen with Garmin navigation, 28 GB hard drive), and the optional REZ rear-seat DVD entertainment module - all keep their serial on a printed chassis label. The Caravan continued with these legacy radios all the way through the end of production rather than moving to the Uconnect 8.4 platform, so the head unit has to come out for the sticker to be read.
Safety first. Switch the ignition off, remove the key, disconnect the negative battery terminal, and wait several minutes before touching wiring. Avoid the yellow airbag/SRS connectors entirely and use plastic trim tools so nothing shorts or breaks.
Tools you will need. Plastic trim removal kit, Phillips screwdriver, small Torx bit set, flashlight, and a 7 mm socket on hand for any deeper retaining bolts.
Removal overview. Ease the centre stack bezel forward at the lower edge using a plastic pry tool and work up the sides - on the post-2011 Caravan dash it is held in by four friction clips with no visible screws on the bezel. With the four clips released, lay the bezel aside on a soft cloth (on this body it does not need to be unplugged from any harness). Remove the four screws securing the radio chassis to the dash bracket, slide the radio forward, and disconnect the antenna lead and the multi-pin power/data harnesses on the rear.
Where the serial sits. The serial number is printed on a barcode/sticker label on the top or side of the chassis, next to the part number and supplier markings. The REZ rear-seat DVD module wears the same kind of printed label on its own case.
Tips. Photograph the label up close in good light and double-check ambiguous characters such as 0/O and 1/I before submitting the serial.

Common Serial Number Structures
The 2019 Dodge Caravan's Uconnect 8.4" (RA3) uses these common serial formats:
T00AM– Harman VP2 Uconnect (most common format)T00BE– Continental-made variantTM9– Older Harman production
Radio designation: RA3 (or VP2 with optional premium audio). Serial: 14 characters.
Note The Caravan's label includes a part number (P05064... or 68...). The serial number alone is used for the unlock code.
What a Valid Serial Number Looks Like
The factory radios fitted to the 2019 Grand Caravan are legacy Mopar head units rather than the later Uconnect 8.4 platform, so the prefix on the chassis label varies with which radio was specified and which supplier built it.
RBZ MyGIG 430 and RHB MyGIG 430N
These Mitsubishi-built MyGIG units typically print an alphanumeric serial on the case sticker. Common Mopar/MyGIG prefixes seen on this generation include TM9 alongside other T-style codes. The serial usually runs as a continuous block of letters and digits with no dashes or spaces.
RES (single-CD)
The base RES head unit usually carries a Mopar-style serial on a chassis sticker. Treat the printed label on the unit itself as the authoritative reference and copy each character exactly.
REZ rear-seat DVD module
The optional REZ overhead DVD entertainment unit also wears a printed chassis label with its own serial. If codes are needed for that module, transcribe its serial separately and avoid guessing unclear characters.
How Code Entry Works on Your Dodge Radio
Once you receive the correct unlock code based on the serial number, you can restore normal functionality by entering it into the unit.
The code entry process depends on the head unit design, but most 2019 Caravan 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.
Entering Process
Code entry on the 2019 Caravan's Uconnect 8.4":
- With ignition ON, the screen shows "ENTER CODE".
- Use the on-screen keypad to enter your 4-digit code. The Caravan's 8.4" screen is easy to reach from the front.
- The radio unlocks automatically after the 4th digit — no confirm button is needed.
Lockout: 3 wrong entries = 60-minute lockout. Leave ignition ON. Turning it off starts the countdown over.
In-depth Entering Instructions for Caravan 2019
Once the unlock code has been retrieved for a 2019 Grand Caravan radio, it can be entered straight at the head unit - no scan tool or dealer visit is required.
Limited attempts. Mopar head units only accept a small number of incorrect tries (commonly three) before going into a long lockout/WAIT state, so confirm each digit before pressing it.
Entering the code. Place the ignition in RUN/ACC so the radio powers up but the engine stays off. Wait for the display to show CODE, Enter Anti-Theft Code, or a similar prompt. On the RBZ/RHB MyGIG (6.5-inch) units, type the digits using the on-screen number pad and confirm with the on-screen OK/Enter button. On the base RES head unit, press the numbered preset buttons (1-6) in sequence and confirm with the tune/menu knob or labelled enter button as prompted on the display.
If a wrong code was entered. If WAIT or a similar timeout appears after the failed-attempt limit is reached, leave the radio powered with the ignition in RUN for a continuous 30 minutes before trying the correct code again.
Why Did the Radio Lock and Ask for a Code?
Minivan owners face radio lockouts most often because of:
- Heavy family use battery wear — Family vehicles with constant use of chargers, DVD players, and rear fans drain batteries faster, making replacements more frequent and each one locks the radio.
- Extended parking — family minivans parked for extended periods can deplete the battery.
- Battery replacement — any battery swap activates the lock.
- Used purchase — Caravans are popular used family purchases, so owners find it locked when they buy one.
The code is permanently linked to the radio serial number and never changes.
Understanding Unlock Issues with Your Caravan
A wrong code on the Caravan usually indicates the wrong serial was used. The RA3 label contains both the serial (14-char code, prefixed by T00AM, T00BE, or TM9) and the part number (P... or 68...) — only the serial generates a code.
Verify the number via Dealer Mode or the label and contact support for a free re-check if needed.
The Caravan's Uconnect 8.4" uses touchscreen-only code entry — no preset buttons are involved. When the locked screen shows:
- Press each number on the touchscreen.
- The radio confirms after the last digit entered — no confirm step is needed.
Should taps not register, cycle the ignition and allow 30 seconds.
The RA3 label on the Caravan's radio contains multiple numbers:
- Serial number — 14 alphanumeric characters, starting with
T00AM,T00BE, orTM9. Submit this. - Part number — begins with
P05064or68. Ignore this.
Your quickest option: Dealer Mode — System Info → Radio Part Info → Serial Number. No tools needed.
Three wrong attempts on the Caravan's Uconnect trigger a 60-minute lockout showing "WAIT":
- Leave the Caravan's ignition ON — engine off is fine but ignition must remain ON.
- Allow the full 60 minutes.
- Turning the Caravan off resets the timer.
After 60 minutes, re-enter carefully with the verified code.
If the Caravan's radio doesn't show the code screen after a battery event:
- Ensure the ignition is in ON (not just ACC) and give the system a moment to boot up.
- Check the radio fuse — fuse failure prevents any display.
- Certain models respond to a brief touch to activate the code entry screen.
If the screen stays dark, power delivery issue is worth checking first.
