How it works
One number, three steps, a couple of minutes.
- 1 Read the number on the label Pull the radio a few centimetres forward and read the number off its label - nothing has to be unplugged.
- 2 Type it in the form Just the serial and your email. The format check runs before the payment step.
- 3 The code is delivered instantly 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.
Money-back guarantee if the code does not open your radio.

Identify Your Factory Radio
Before requesting a radio code it is important to confirm the exact model. Match the design, controls, display and features below with the unit in your dashboard.
Typical identification features:
- 6.5" touchscreen in the centre of the dash
- A navigation unit - maps installed from the factory
- A Right-hand drive / Rest of World-market build
- Sales code REX on the chassis label
- Label serial opening with T00AM, T00BE, T0012
It is the MyGIG NTG4 REX when:
- the chassis label carries the REX sales code
- the printed serial opens with T00AM, T00BE, T0012
- the build year falls inside 2009-2012
- the screen is the 6.5" touchscreen fitted to the MyGIG NTG4
REX is rare. If your vehicle is RHD and the radio shows a hard-drive nav, REX is most likely. North American owners almost never have REX - check the part number against this page's supported list before paying.
What Is the MyGIG NTG4 REX Radio?
The MyGIG NTG4 REX is a dealer-installed Chrysler audio and multimedia unit. Alongside standard radio and audio playback it may include touchscreen controls, Bluetooth, CD/DVD playback or factory navigation, depending on how the vehicle left the factory.
REX is a lower-volume export navigation MyGIG variant - 6.5-inch touchscreen with HDD navigation, mostly shipped into right-hand-drive and selected European markets. Identical user interface to RER.
The MyGIG NTG4 REX was installed in various Chrysler models between 2009-2012. It was commonly fitted to vehicles built on the Harman multimedia platform and remains one of the more recognisable factory radios of that period.
Features you may find on the MyGIG NTG4 REX:
6.5" touchscreen
AM/FM radio
Built-in navigation with factory maps
Internal hard drive for ripped music
CD playback
AUX and USB input*
Steering wheel control support
Anti-theft security code
*Availability varies with the vehicle configuration.
The MyGIG NTG4 REX carries the same anti-theft protection as most factory units. Once power is cut - a flat battery, a battery swap, or the radio being removed - it will ask for the original code before it plays again.
Platform details and official documentation are available from Uconnect support at driveuconnect.com.
Your MyGIG NTG4 REX Serial Number - Where to Look
Your unlock code is tied to the radio's serial number, so it is the one detail the form asks for. The number lives on the label printed on the housing of the radio itself.
On this unit: Top of the chassis. Radio removal required.
Three steps to the serial number:
- Bring the radio out of its slot; release keys do it in a minute and nothing needs disconnecting.
- The serial is on the chassis sticker, usually right by the barcode - copy it down.
- Enter it exactly as it appears - no spaces, no dashes.

The Situations That Lock a MyGIG NTG4 REX
A locked MyGIG NTG4 REX is almost always the result of one of four everyday situations, none of which mean anything is broken.
A used car with a locked radio
Second and third owners almost never get the code card. The radio itself still carries everything needed - its serial number.
A unit from a breaker
Replacement radios are the classic case: every unit has its own code tied to its own serial. Read the serial off the newly fitted radio and order for that one.
New battery, locked radio
The most common trigger by far: the moment the battery is swapped, the radio forgets it was ever unlocked and asks for its code on the next start.
Back from the mechanic, radio locked
Mechanics often disconnect the battery before electrical work. The car comes back fixed and the radio comes back locked - expected, not a fault.
Whichever of these applies, the fix is identical: the serial number off the radio, the form at the top of this page, and the code is emailed in seconds.

The vehicles listed above are the most common factory applications for the MyGIG NTG4 REX. Equipment packages and regional specifications differ, so verify the radio using its design, serial number or part number before requesting a code.
Entering the code on the MyGIG NTG4 REX
Nothing to install and no tools needed - just the four digits.
- Give the radio power - key to accessory is enough - and wait for the code prompt.
- The screen shows a numeric keypad for the four digits.
- Punch in all four digits, first to last.
- Verification happens by itself once the fourth digit is in.
- The security screen disappears and the unit returns to normal operation.
Common problems
The radio is counting down
A countdown means the anti-theft system is holding the unit. Leave the ignition on until it clears. Three wrong attempts triggers a 60-minute WAIT. Leave the ignition on while waiting.
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. Radio removal required.
The radio locked itself again
Expected behaviour: the security system trips again whenever power is cut. Battery disconnect or replacement.
This radio looks like several others
A few models in this family share the same face, so the label is what settles it. REX is rare. If your vehicle is RHD and the radio shows a hard-drive nav, REX is most likely. North American owners almost never have REX - check the part number against this page's supported list before paying.
Save the code: it stays valid, so the next battery change costs you nothing.
