Can't Locate Your Radio Serial Number? Follow These Steps for Dodge Grand Caravan 2020
The useful thing to know is that factory radios use a specific S/N to identify each unit.
The anti-theft system links the code directly to this serial.
Different from car-specific data such as VIN or registration info, it is not determined by the model or production year, so you'll be able to retrieve it even if you have a radio that you installed afterwards.
Depending on the manufacturer and radio installed in your Dodge Grand Caravan, the retrieval method is different.
These are the best ways to locate it.
Identify Your 2020 Grand Caravan's Factory Radio
2020 was the final model year of the Grand Caravan, and the radio lineup ended exactly where it began in 2013 - the legacy Mopar trio with no Uconnect 8.4 platform ever introduced. Identify yours below:
- RES - Media Center 130 (base). Non-touchscreen AM/FM/CD radio. Small monochrome single-line display, hard preset buttons and rotary tune/volume knobs - no screen graphics, no NAV button, no factory Bluetooth. Standard on SE/SE Plus and the most common fit out the door.
- RBZ - 430 MyGIG (6.5" touchscreen, no nav). Glossy black bezel, 6.5-inch color touchscreen, hard buttons for Radio, Media, Controls, More and Phone flanking the screen. No NAV soft key on the home page because it has no navigation hardware. Standard on SXT and GT - the dominant touchscreen variant by far.
- RHB - 430N MyGIG (6.5" with Garmin nav). Externally identical to RBZ - same Mitsubishi-built 6.5-inch screen, same bezel, same hard keys. The on-screen tells: a NAV soft key on the home menu, a Garmin splash logo at startup and a 28GB hard drive for stored music. Rare option even by 2020.
- Optional rear-seat DVD entertainment. Overhead 9-inch flip-down headliner screen with a separate DVD player in the lower dash and wireless IR headphones; orderable with any of the three head units.
Quick Method: Find the Serial Number on the Screen
These are the steps you need to follow for 2020 Dodge Grand Caravan:
The 2020 Dodge Grand Caravan is Dodge's full-size minivan and comes equipped with the Uconnect 8.4" (RA3) touchscreen. The serial number is accessible on screen through Dealer Mode.
Climate Button Method:
- Turn the ignition to ACC or ON.
- In the Grand Caravan's center console, the Climate Up, Climate Down, and Front Defrost buttons sit below the 8.4" display. Press and hold all three simultaneously for 5 seconds.
- Dealer Mode opens on screen.
- Select: System Info → Radio Part Info → Serial Number.
Alternative Method: Hold Temperature Up (red) and Temperature Down (blue) together for 5 seconds to access Engineering Mode, then navigate to the serial.
Pulling Out the Radio Unit to View the S/N on the Tag
If the serial number cannot be accessed through menu, use the pull-out method.
Most Dodge Grand Caravan original radios include a tag with the serial number printed on the housing.
The process:
- Shut down the car.
- Lift away surrounding mounting frame.
- Loosen screws holding the radio.
- Slide outward to inspect the label.
Should Dealer Mode be blocked on your 2020 Grand Caravan, the RA3 radio must be removed to read the serial label. The Grand Caravan's spacious center console gives adequate access for this work:
- Remove the center stack bezel – The Grand Caravan's center bezel surrounds the 8.4" screen and climate controls. A plastic pry tool pops off the friction-clipped panel — begin at the lower corners.
- Remove the 4 Torx T20 screws – At the radio mounting frame corners.
- Slide the radio out – Pull the unit forward enough to access the serial label on the top or side surface.
The 14-character serial is on a barcode sticker. Wiring can remain plugged in.
Serial Number on the Unit
The factory head units offered on the 2020 Grand Caravan - the final model year before the nameplate was retired - continued with the same legacy lineup: the RES single-CD radio (standard on most trims), the RBZ MyGIG 430 (6.5-inch touchscreen, with the Single-DVD Entertainment Group), the RHB MyGIG 430N (6.5-inch touchscreen with Garmin navigation, 28 GB hard drive), and the optional REZ rear-seat DVD entertainment module. None of these legacy radios expose the serial through the screen, so the head unit has to come out for the printed chassis sticker to be read.
- Safety first: switch the ignition off, remove the key, disconnect the negative battery terminal, and wait several minutes; never disturb the yellow airbag/SRS connectors and use plastic trim tools to keep clips and metal contacts intact.
- 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.
- Ease the centre dash bezel forward at the lower edge using a plastic pry tool and work up the sides; on the post-2011 Grand Caravan dash the bezel is held by four friction clips with no visible screws.
- 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 to free the radio.
- 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 at the rear.
- 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.
- Photograph the label up close and double-check ambiguous characters such as 0/O and 1/I before submitting the serial.

Typical Serial Number Formats for 2020 Grand Caravan Radios
The factory radios fitted to the 2020 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
TM9alongside otherT-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 Our Radio Code Generator Works for 2020 Dodge Grand Caravan
Vehicle radios use anti-theft codes dependent on the radio unit itself rather than the model or production year.
- Our lookup service works by matching your Dodge Grand Caravan radio's serial number.
- After entering the serial into the form above, the system identifies the radio unit and retrieves the corresponding code.
- You can then enter the code directly into your Dodge radio.
- The online process is quicker and more accessible than visiting the Dodge dealer.
Got the Code? Here's How to Enter It
When you obtain 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 control layout, but most 2020 Grand 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 CODE displayed on screen.
Entering Process
To unlock the Grand Caravan's radio using the Uconnect 8.4":
- Ignition ON. Screen presents "ENTER CODE".
- Use the touchscreen number pad to enter each digit of the 4-digit code on the Grand Caravan's screen.
- The radio auto-confirms after the 4th digit — no extra step needed.
Lockout: 3 incorrect entries = 60-minute lockout. Keep ignition ON. Turning it off extends the wait.
Step-by-Step Code Input Guide
Once the unlock code has been retrieved for a 2020 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.
- 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; on the base RES head unit, press the numbered preset buttons (1-6) in sequence.
- Confirm the entry with the on-screen OK/Enter button on the MyGIG units, or with the tune/menu knob (or labelled enter button) on the RES.
- If
WAITor 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?
Full-size minivan owners most frequently encounter this because of:
- Heavy family use and battery strain — The Grand Caravan's role as a family hauler with heavy accessory loads wears batteries more quickly, increasing replacement frequency and every replacement triggers the code.
- Long periods parked — family minivans going undriven between trips can lose enough charge to lock the radio.
- Battery replacement — any battery swap triggers the lock.
- Used purchase — minivans change hands often, so many new owners find the radio locked at purchase.
The unlock code is permanently assigned to the serial number and remains valid.
Fixing Common Code Entry Problems for 2020 Grand Caravan
Rejected unlock code on the Grand Caravan's Uconnect typically points to a serial number mismatch. The RA3 label has the serial (T00AM, T00BE, or TM9, 14 characters) and the part number (P... or 68...) on the same sticker — just the serial is needed.
Re-check via Dealer Mode or the physical label and contact support for a free re-check if needed.
If no "ENTER CODE" appears after a battery event:
- Confirm the ignition is in ON (not ACC) and give a moment for the system to start.
- Inspect the radio fuse — a blown fuse prevents the display from activating.
- Certain models may need a screen tap to bring up the code entry prompt.
Should nothing appear, a blown fuse is the first thing to investigate.
The Grand Caravan's Uconnect enters a 60-minute lockout after 3 wrong code attempts. The screen displays "WAIT":
- Keep the Grand Caravan's ignition ON — car can be off but key must stay in ON.
- Allow the complete 60 minutes.
- Turning off the ignition resets the timer.
After the 60 minutes, re-enter the correct code.
The Grand Caravan's Uconnect 8.4" uses touchscreen-only input for code entry — no physical buttons are involved. When "ENTER CODE" is shown:
- Tap each digit on the on-screen keypad.
- The radio confirms after the 4th digit — no "Enter" key is needed.
Should taps not respond, restart by turning the ignition off and back on.
The Grand Caravan's RA3 radio label shows more than one number:
- Serial number — 14 characters, prefixed by
T00AM,T00BE, orTM9. Use this one. - Part number — begins with
P05064or68. Do not use this.
On this model, Dealer Mode gives the serial directly: System Info → Radio Part Info → Serial Number. No physical access required.
