Can't Find Your Radio Serial Number? Follow These Steps for Chrysler Grand Caravan 2015
The initial step is finding the radio serial number.
Many people assume the code depends on the Chrysler model or year, but actually, the whole process depends on the unique radio's serial number.
The serial is the key used to calculate the correct unlock code.
This is actually better, because if you have bought a used radio, the VIN or other Chrysler-specific data wouldn't help.
Depending on the radio used, you may be able to retrieve the serial directly from the screen or by looking at the label on the radio chassis.
Identify Your 2015 Grand Caravan's Factory Radio
The 2015 Grand Caravan continued the same three-radio fleet with no hardware updates - the Uconnect 8.4 platform never came to this minivan. Identify yours below:
- RES (Media Center 130) - base AM/FM/CD. Non-touchscreen, single-line monochrome display, large rotary tune/volume knobs and a row of hard preset buttons. No screen, no NAV button, no factory Bluetooth. Standard on lower-trim Canadian-market vans and the dominant fit.
- RBZ (430 MyGIG) - 6.5-inch touchscreen, no nav. Volume touchscreen variant with a glossy black bezel and hard keys (Radio, Media, Controls, More, Phone) flanking the screen. No NAV soft key on the touchscreen home page because it lacks navigation hardware.
- RHB (430N MyGIG) - 6.5-inch touchscreen with Garmin nav. Same 6.5-inch screen and bezel as the RBZ and indistinguishable from the outside; identification is software-side - a NAV soft key on the home menu, the Garmin splash logo at startup and a 28GB hard drive for ripped music. Optional and rarer than the RBZ.
- Optional rear-seat DVD entertainment. Overhead 9-inch flip-down screen with a separate DVD player in the lower dash and wireless headphones; independent of the head unit and orderable on higher trims.
Before Removing the Radio, Try This Screen Method
These are the steps you need to follow for 2015 Chrysler Grand Caravan:
The 2015 Chrysler Grand Caravan — the iconic American family hauler with fold-flat second and third rows — is equipped with the Uconnect 8.4" Classic (RA3). The Grand Caravan's center stack positions the climate controls right underneath the 8.4" touchscreen, making the Dealer Mode button combination easy to access.
Press and hold Climate Up, Climate Down, and Front Defrost simultaneously for 5 seconds with ignition in ACC or ON. Dealer Mode opens. Go to: System Info → Radio Part Info → Serial Number.
Pulling Out the Radio Unit to View the S/N on the Tag
If the serial does not appear on display, the next step is checking the radio itself.
Many Chrysler radios require physical access to the ID label attached to the unit.
Typical approach:
- Start by completely shutting off the engine - pull the key out.
- Then remove the trim panel.
- Next, loosen the mounting points and pull the radio forward.
- Look for a printed tag showing the serial number.
If Dealer Mode is unavailable on the 2015 Chrysler Grand Caravan, remove the RA3 from the Grand Caravan's family-oriented center stack.
- Pry off the trim panel with a plastic trim tool.
- Remove the 4 Torx T20 mounting screws.
- Pull the unit forward to read the serial label on the side or back of the chassis.
The Grand Caravan's no-nonsense center stack makes the trim removal relatively straightforward.
Serial Number on the Unit
The factory head units offered on the 2015 Grand Caravan - typically the RES single-CD radio, the RBZ MyGIG 430 (6.5-inch touchscreen), the RHB MyGIG 430N (6.5-inch touchscreen with navigation), and the optional REZ rear-seat DVD entertainment module - all keep their serial on a printed chassis label. Because these legacy radios do not expose the serial on screen, the unit has to come out for the sticker to be read.
- Safety first: turn 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.
- 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 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 of the unit.
- The serial number is printed on a barcode/sticker label on the top or side of the chassis next to the part number; the REZ rear-seat DVD module wears the same kind of printed label on its own case.
- Photograph the label and double-check ambiguous characters such as 0/O and 1/I before submitting the serial.
