Can't Find Your Radio Serial Number? Follow The Steps Below for Dodge Grand Caravan 2014
The initial step is writing down the radio S/N.
Many drivers assume the code depends on the Dodge model or year, but in reality, the unlock process relies on the unique radio's serial number.
This number identifies the exact head unit installed in your Dodge Grand Caravan.
This is actually better, because if you have bought an aftermarket radio, the VIN or other Dodge-specific data wouldn't be of much use.
Depending on the radio used, you may be able to see the serial directly from the display or by looking at the label on the radio chassis.
2014 Grand Caravan - Which Radio Did You Get?
For 2014 the Grand Caravan kept the same legacy Mopar trio carried over from 2013 - no platform changes, no Uconnect 8.4. Identify yours by the bullets below:
- RES - Media Center 130 (base AM/FM/CD). Non-touchscreen unit with a small one-line display, physical hard preset buttons and large rotary knobs. No NAV button, no factory Bluetooth, no SiriusXM out of the box. Standard on AVP/SE; this was the most common factory radio.
- RBZ - Media Center 430 MyGIG (6.5" touchscreen, no nav). 6.5-inch color touchscreen with hard keys for Radio, Media, Controls, More and Phone flanking the screen. No NAV soft key on the home menu because it has no navigation hardware. Optional on SXT, standard on Crew/R/T - the volume touchscreen option.
- RHB - Media Center 430N MyGIG (6.5" with Garmin nav). Visually identical bezel to the RBZ, same Mitsubishi-built 6.5-inch touchscreen and same hard buttons. The difference is on-screen: a NAV soft key on the home menu, a Garmin logo at boot and a 28GB internal hard drive for stored music. Optional top-tier choice and rarer than RBZ.
- Optional rear-seat DVD entertainment. Separate 9-inch flip-down overhead screen with its own DVD player in the lower dash and wireless IR headphones; recognised by the headliner-mounted screen and independent of the head unit.
Access the S/N on the Radio Screen
The method for 2014 Dodge Grand Caravan is this:
The 2014 Dodge Grand Caravan seats up to 7 or 8 passengers and features 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. Hold all three at once for 5 seconds.
- Dealer Mode launches on screen.
- Go to: System Info → Radio Part Info → Serial Number.
Alternative Method: Hold Temperature Up (red) and Temperature Down (blue) together for 5 seconds to enter Engineering Mode, then follow the same menu.
Find it by Pulling Out the Radio Unit
If the serial number cannot be accessed through menu, use the removal method.
Most Dodge Grand Caravan OEM radios include a label with the serial number printed on the housing.
Basic process:
- Disable power.
- Lift away surrounding dashboard trim.
- Remove fasteners holding the radio.
- Slide outward to inspect the label.
Should Dealer Mode be unavailable on your 2014 Grand Caravan, the RA3 radio must be removed to see the serial label. The Grand Caravan's spacious center console provides good access for this work:
- Remove the center stack bezel – The Grand Caravan's center bezel covers the display and HVAC area. Trim removal tool releases the friction-clipped panel — start from the bottom.
- Remove the 4 Torx T20 screws – At the radio mounting frame corners.
- Slide the radio out – Ease the unit out to reveal the serial label on the side or top surface.
The 14-character serial is on a barcode sticker. The harness can stay connected.
Grand Caravan's Hardware Label Method
The factory radios offered on the 2014 Grand Caravan - typically the RES single-CD head unit, the RBZ MyGIG 430 (6.5-inch touchscreen), the RHB MyGIG 430N (6.5-inch touchscreen with Garmin navigation), and the optional REZ rear-seat DVD entertainment module - all carry their serial number on a printed chassis label. Because these legacy units do not expose the serial through the touchscreen, the head unit needs to come out so the sticker on the case can be read.
- Safety first: switch the ignition off, remove the key, disconnect the negative battery terminal, and wait several minutes before touching wiring; never disturb the yellow airbag/SRS connectors 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 if any retaining bolts need backing out further into the dash.
- Ease the centre dash bezel forward at the lower edge using a plastic trim tool and work up the sides; on the post-2011 Grand Caravan dash it is held in by four friction clips with no visible screws on the bezel itself.
- Once the four clips release, set the bezel aside on a soft cloth - on this body it does not need to be unplugged from any harness to do the job.
- Remove the four screws securing the radio chassis to the dash bracket.
- Slide the radio forward and unplug the antenna lead and the multi-pin power/data connectors on the rear of the unit.
- The serial number is printed on a barcode/sticker label on the top or side of the radio chassis, next to the part number and supplier markings; on the optional REZ rear-seat DVD module, the same kind of label sits on the unit's case.
- Photograph the label up close and double-check ambiguous characters such as 0/O and 1/I before submitting the serial.

Common S/N Formats Used on 2014 Grand Caravan Units
The factory radios fitted to the 2014 Grand Caravan are legacy Mopar units rather than the later Uconnect 8.4 platform, so the prefix on the chassis label depends on which head unit was specified and which supplier built it.
RBZ MyGIG 430 and RHB MyGIG 430N
- These Mitsubishi-built MyGIG head 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 is usually a continuous run 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.
Code Entry Process for 2014 Grand Caravan
Once you have the radio serial and generated the unlock code, the next part is entering it into your radio.
Dodge OEM units display a locked screen when ready for input.
The process is usually simple, but button layouts and confirmation methods may change depending on the radio version installed in your Grand Caravan.
Entering Process
Code entry on the 2014 Grand Caravan 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.
Entering Process Explained
After retrieving the unlock code for a 2014 Grand Caravan radio, the digits 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 verify each 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,Enter Anti-Theft Code, or a similar prompt. - On the RBZ/RHB MyGIG (6.5-inch) units, key in 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.
Fast Dodge Grand Caravan Radio Unlock Process Explained
- Skip long troubleshooting discussions or service visits - you can find the code online with the radio serial number.
- First locate your radio's serial. The best place to search is on the unit itself, and sometimes it can be visible on the Grand Caravan's display.
- Type it into the field above, and the software will calculate the correct 2014 Grand Caravan unlock code.
- When you receive the code, input it using Grand Caravan's radio buttons to release the blockade successfully.
- The entire process takes only a few minutes and requires minimal effort.
Understanding Unlock Issues with Your Grand Caravan
If no "ENTER CODE" appears after a battery event:
- Confirm the ignition is in ON (not ACC) and allow 15–20 seconds for the system to initialize.
- Inspect the radio fuse — a blown fuse prevents the display from powering on.
- Certain models may require a brief touch to activate the code entry prompt.
If the screen stays blank, a blown fuse is the most likely cause.
The Grand Caravan's Uconnect 8.4" uses touchscreen-only input for code entry — no preset keys are used. Once the locked screen appears:
- Tap each digit on the on-screen keypad.
- The radio confirms after the final number — no "Enter" key is needed.
If the touchscreen is sluggish, restart by turning the ignition off and back on.
A code rejection on the Grand Caravan's Uconnect typically points to a serial number mismatch. The RA3 label displays both the serial (T00AM, T00BE, or TM9, 14 characters) and the part number (P... or 68...) on the same sticker — only the serial is needed.
Re-check via Dealer Mode or the physical label and reach out for a free re-check if needed.
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 removal needed.
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 — engine doesn't need to run but key must stay in ON.
- Wait the complete 60 minutes.
- Turning off the ignition restarts the countdown.
After the 60 minutes, re-enter the correct code.
What Caused the Radio to Lock?
Grand Caravan owners face radio lockouts 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, leading to more battery changes and each one locks the radio.
- Long periods parked — Grand Caravans going undriven between trips can lose enough charge to lock the radio.
- Battery replacement — routine battery service triggers the lock.
- Used purchase — Grand Caravans are frequently bought and sold used, so many new owners encounter the locked radio.
The unlock code is permanently tied to the serial number and never changes.
