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
  • Factory navigation with maps built in
  • Built for the Right-hand drive / Rest of World market
  • Sales code REX on the chassis label
  • Serial number starting with T00AM, T00BE, T0012

  • the vehicle was built between 2009-2012
  • the screen is the 6.5" touchscreen fitted to the MyGIG NTG4
Careful - there is a lookalike

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.

Chrysler used the MyGIG NTG4 REX on selected models produced between 2009-2012, typically alongside the Harman multimedia platform. It is one of the factory units most often seen from that era.

Features you may find on the MyGIG NTG4 REX:

6.5" touchscreen

AM/FM radio

Built-in navigation with factory maps

Music hard drive for ripped discs

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.

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:

  1. Ease the radio out of the dash - most units need a pair of release keys, which cost a few dollars online.
  2. Read the serial from the factory sticker on the housing, next to or under the barcode.
  3. Type it into the form exactly as printed, with no spaces or dashes.
Format on the label: T00AM followed by 9 more characters; T00BE or T0012 followed by 9 digits (for example T00BE123456789).

Entering the code on the MyGIG NTG4 REX

Nothing to install and no tools needed - just the four digits.

  1. Put the key in accessory position so the unit powers up and asks for the code.
  2. A four-digit keypad appears on the display.
  3. Tap the four digits of your code in order.
  4. There is no separate OK button - the radio checks the code on the last tap.
  5. On a correct code the radio leaves security mode and plays again.

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.

I cannot find the serial number

It is printed on the housing, so the unit normally has to come forward to read it. Top of the chassis. Radio removal required.

Why it happened again

That is normal - the anti-theft system re-arms every time the unit loses power. Battery disconnect or replacement.

I am not sure I have the right variant

Close relatives of this unit look almost identical from the driver's seat. 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.

Frequently Asked Questions

Usually yes, because the serial is printed on a label on the unit itself rather than shown on screen. Release keys are cheap and the unit only has to come forward far enough to read the label - the wiring can stay connected.

No. The code for the MyGIG NTG4 REX comes from the radio's own serial number, not from the vehicle identification number. A VIN lookup only works on Renault and Dacia units - for every other make, including this one, the serial from the radio label is what we need.

The code is generated automatically as soon as the payment goes through, so it appears on screen within seconds and lands in your inbox at the same time. The service runs around the clock, so there is no queue and no waiting for office hours.

It is. The code is calculated with the manufacturer's own algorithm from your serial number, so it is the exact code a dealer would look up - the difference is the price and the fact that you do not have to book an appointment.

You get your money back. Send us a short video showing the serial number and the code being entered, and we return the full amount - no argument, no restocking fee.

Pricing depends on the radio family and starts at $9.99. The exact amount for your serial is shown at checkout before you pay anything, so there is no surprise at the end.

What Happens After You Order

The original code on screen within seconds of payment, emailed to you as well.

Full money-back guarantee if the code does not open your radio.

Available 24/7 - no appointment, no dealer visit, no towing.

Works every time - the code stays valid for the life of the radio.
