  2. 2 Put it in the form on the left Copy it character for character. We check the format up front, so a typo never costs you anything.
  3. 3 Your code lands in seconds The code is on screen in seconds and in your inbox. It never expires and keeps working every time power is cut.

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

This is probably your radio if:

  • 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
Careful - there is a lookalike

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.

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

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:

  1. Bring the radio out of its slot; release keys do it in a minute and nothing needs disconnecting.
  2. The serial is on the chassis sticker, usually right by the barcode - copy it down.
  3. Enter it exactly as it appears - no spaces, no dashes.
Format on the label: T00AM and then 9 more characters; T00BE or T0012 and then 9 more digits, e.g. T00BE123456789.

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.

Factory Part Numbers 7

All of the part numbers listed here are covered. Match the one printed on your unit's label and you are in the right place.

P05091098AC P05107098AD P05107098AE P05107098AF P05107098AG P05107098AH P05107098AI

You will find the part number on the chassis label of the unit, normally alongside the serial. A match in this list confirms you are on the right page for the MyGIG NTG4 REX.

Models Featuring the MyGIG NTG4 REX

Vehicle Model Typical Production Years Notes
Chrysler 300C RHD, Voyager (UK/Australia) 2009-2012
Jeep Grand Cherokee WK RHD, Wrangler JK RHD 2009-2012
Lancia Thema and Voyager rebadges (limited) 2009-2012

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.

  1. Give the radio power - key to accessory is enough - and wait for the code prompt.
  2. The screen shows a numeric keypad for the four digits.
  3. Punch in all four digits, first to last.
  4. Verification happens by itself once the fourth digit is in.
  5. 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.

Frequently Asked Questions

Yes, and it is the smart move: order while the timer runs down, and by the time the radio accepts input again the code is already in your inbox. The lockout only blocks code ENTRY, not code retrieval.

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 identical to what the dealer would give you - the difference is the price and the fact that you do not have to book an appointment.

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

Yes, and this is one of the most common orders. It makes no difference where the unit came from - the code is generated from the serial on ITS label, so read the serial off the replacement unit and enter that.

From Drivers Who Unlocked Their Radio

These are real orders and real radios. Hundreds more are on the reviews page.

"This was a simple procedure. My Chrysler 300s, I found out my radio S/N (I had to disassemble the radio to get it) and on my vehicle I had 2. The main unit was the right S/N to use and paid my fee, at the same time received my code. It beats paying an $100 + to get it from the dealership."

I originally called the dealer and they said I needed to bring my car in and bring the title and ID. I found this sote from YT. I was skeptic at first but it worked right away.

Had to replace the head unit and bought one on eBay but the anti theft code wasn’t provided. This option to get it worked out well
