Your code in three steps
Everything runs from the serial number on the radio's own label.
- 1 Check the unit's sticker Look for it on the chassis label. The radio normally has to come forward a little - the wiring can stay plugged in.
- 2 Paste it into the box Letters and digits as they appear on the label - the form validates them before payment.
- 3 Unlock the radio You get the digits at once, with an email copy to keep. Type them into the radio and it plays again.
If it does not work, you are refunded in full.
Your radio carries a label like this one. The serial is the code printed on it.

Check If This Is Your Radio
Compare the design, controls, display and features listed below with your factory-installed radio - the Uconnect 8.4 RA4 VP4 NA is easy to tell apart once you know what to look for.
What the Uconnect 8.4 RA4 VP4 NA looks like:
- 8.4" touchscreen in the centre of the dash
- Built-in navigation with factory map data
- Built for the North America market
- RA4 VP4 NA printed on the factory label
- Serial number starting with T00AM, T00BE, T0012
This is probably your radio if:
- RA4 VP4 NA appears as the sales code on the label
- the printed serial opens with T00AM, T00BE, T0012
- the model year sits within 2014-2018
- the display matches the Uconnect 8.4 8.4" touchscreen
RA4 has the NAV tile. If tapping NAV returns "Feature not available" you have RA3, not RA4. VP4 is the second-generation Uconnect 8.4 platform - it boots faster than the VP3 RA4 and has Apple CarPlay/Android Auto support in later model years.
Uconnect 8.4 RA4 VP4 NA Overview
Fitted as factory equipment in selected Chrysler models, the Uconnect 8.4 RA4 VP4 NA handles audio playback and vehicle integration from the factory. Depending on the version, it can also add Bluetooth, touchscreen operation, CD/DVD playback, navigation or wider multimedia support.
Uconnect 8.4 RA4 (VP4 North America) is the most common 8.4-inch navigation Uconnect in US-market FCA vehicles - 8.4-inch touchscreen with built-in maps, SiriusXM Travel Link, climate controls integrated into the screen on most vehicles. The home screen shows a NAV tile alongside Radio, Media, Phone.
Between 2014-2018 the Uconnect 8.4 RA4 VP4 NA appeared across a number of Chrysler models, usually on vehicles using the Harman multimedia platform. It stayed in production long enough to become a common sight in that generation of cars.
Typical features include:
8.4" touchscreen
AM/FM radio
Navigation built in, with factory map data
SiriusXM satellite radio*
Bluetooth for hands-free calls and music streaming
USB media playback
Steering wheel control support
Anti-theft security code
*Availability varies with the vehicle specification.
As with other Harman factory units, the Uconnect 8.4 RA4 VP4 NA locks itself when power is lost. After a battery disconnect or a workshop visit the screen will ask for the original security code before any audio returns.
Platform details and official documentation are available from the official Uconnect site.
What Usually Triggers the Code Screen
Nearly all of the Uconnect 8.4 RA4 VP4 NA codes we generate follow one of these four events.
The seller had no code
Used cars routinely arrive with a locked radio and no code card in the glovebox. The serial number on the unit is all that is needed to recover it.
A different unit is in the dash now
The code does not transfer from one unit to another: the swapped-in unit has a different serial, and that serial is what the code is calculated from.
The battery was replaced
Whether the battery was changed or just ran flat, the radio sees a power loss and asks for the code the next time it starts.
After electrical work
The repair worked - the locked radio is just the side effect of the battery being off the car for a while.
All four roads lead to the same solution - read the serial off the unit, enter it above, and the original code comes back instantly.
How to Read the Serial Number Off Your Uconnect 8.4 RA4 VP4 NA
The code is calculated from the radio's own serial number, so that number is the only thing you need before ordering. It is printed on the factory sticker of the unit itself, not in the vehicle documents.
On this unit: White printed label on the top of the chassis, near the rear edge. Three 7mm bolts and two trim clips release the dash bezel; pull the radio forward enough to read the label from above. No on-screen serial menu is available while the unit is locked.
How to reach the number:
- Slide the radio out of the dash - most units need a pair of release keys, which cost very little online.
- Read the serial from the printed label on the housing, next to or under the barcode.
- Copy it into the form precisely as printed; the checker catches any typo before payment.

How to enter your Uconnect 8.4 RA4 VP4 NA code
Nothing to install and no tools needed - only the code itself.
- Switch the ignition on and let the radio boot to its security screen.
- The code prompt comes up with its own keypad.
- Enter the four digits in the order you received them.
- As soon as the last digit lands, the radio runs the check on its own.
- On a correct code the radio leaves security mode and plays again.
Troubleshooting the Uconnect 8.4 RA4 VP4 NA
The radio is counting down
A countdown means the anti-theft system is holding the unit. Leave the ignition on until it clears. After three wrong codes the screen shows "INCORRECT CODE - WAIT" with a 30-minute countdown. The timer counts down only while the radio has 12V applied (ignition in RUN or ACC) - cutting power restarts the 30 minutes. The radio cannot be permanently locked; the correct code always works once the timer expires.
I cannot find the serial number
It is printed on the housing, so the unit normally has to come forward to read it. White printed label on the top of the chassis, near the rear edge. Three 7mm bolts and two trim clips release the dash bezel; pull the radio forward enough to read the label from above. No on-screen serial menu is available while the unit is locked.
Why it happened again
That is normal - the anti-theft system re-arms every time the unit loses power. Any interruption of 12V power for more than about a minute. Common causes: dead battery, battery replacement, jump-start failure, alternator service, dash repair that disconnected the battery, or pulling the radio out of the dash.
Same face, different radio
One glance at the label settles it - worth doing before the order. RA4 has the NAV tile. If tapping NAV returns "Feature not available" you have RA3, not RA4. VP4 is the second-generation Uconnect 8.4 platform - it boots faster than the VP3 RA4 and has Apple CarPlay/Android Auto support in later model years.
The code belongs to the radio and never changes, so keep it somewhere safe once you have it.
