- 1 Read the number on the label On the factory sticker on the radio housing, beside the barcode. Most units have to come out of the dash - release keys cost a few dollars.
- 2 Enter it in the form Just the serial and your email. The validator runs before the payment step.
- 3 Unlock the radio The code appears the moment the payment clears, and a copy goes to your email. Keep it - the same four digits work for the life of the radio.
If it does not work, you get your money back.
Same label, different radio: yours carries its own serial in this spot.

Everything You Need to Know About the Uconnect 8.4 RJ4 VP4 EU

Uconnect 8.4 RJ4 (VP4 Europe) is the second-spec 8.4-inch navigation Uconnect for select European/RHD applications - VP4 hardware, built-in EU maps, DAB+.
Between 2015-2018 the Uconnect 8.4 RJ4 VP4 EU 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.

Built-in navigation with factory maps
Bluetooth hands-free and audio streaming
USB media playback
SiriusXM satellite radio*

Like many factory-installed radios, the Uconnect 8.4 RJ4 VP4 EU is protected by an anti-theft system. If power is interrupted after replacing or disconnecting the vehicle battery, the unit may request the original radio code before it can be used again.
Finding the Serial Number on the Uconnect 8.4 RJ4 VP4 EU
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: Top of the chassis label.
Getting to the label:
- 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, beside the barcode.
- Type it into the form exactly as printed, with no spaces or dashes.

- Tap the four digits of your code in order.
- Verification happens by itself once the fourth digit is in.
- On a correct code the radio leaves security mode and plays again.
When it does not go to plan
The screen shows a wait timer
A countdown means the anti-theft system is holding the unit. Leave the ignition on until it clears. 30-minute WAIT after three wrong attempts.
Where the number actually is
The serial is on the unit itself, not in the vehicle papers or on the dashboard. Top of the chassis label.
Why it happened again
Expected behaviour: the security system trips again whenever power is cut. Battery disconnect.
This radio looks like several others
The differences are easy to miss, so check this before ordering. RJ4 EU is the navigation variant. RJ3 is non-nav. Distinguish by NAV tile presence.
