How the service works
Everything runs from the serial number on the radio's own label.
- 1 Get the serial off the radio Look for it on the sticker on the housing. The radio normally has to come forward a little - the wiring can stay plugged in.
- 2 Paste it into the box Just the serial and your email. The validator runs before the payment step.
- 3 Get your code The code is on screen in seconds and in your inbox. It never expires and works after every battery disconnect.
Covered by a full refund if the code turns out not to fit your unit.
The sticker on your unit will look similar. Read the serial straight off it.

How to Recognize the Uconnect 735N NTG4 Refresh JNAV RHP
Not sure if your vehicle is equipped with the Uconnect 735N NTG4 Refresh JNAV RHP? Check the design, controls, display and features listed below against your factory radio.
What the Uconnect 735N NTG4 Refresh JNAV RHP looks like:
- Centre-stack 6.5" touchscreen
- Built-in navigation with factory map data
- The chassis label carries the NTG4 Refresh JNAV RHP sales code
- Serial number starting with T00AM, T00BE, T0012
This is probably your radio if:
- the chassis label carries the NTG4 Refresh JNAV RHP sales code
- the serial on the label starts with T00AM, T00BE, T0012
- it came in a car from the 2011-2013 range
- the 6.5" touchscreen is the one the Uconnect 735N family uses
Look for the Jeep logo on boot and Garmin-style map graphics. If the boot logo is Ram, Dodge or Chrysler, you have RHP rather than the Jeep-branded 735N variant - the unlock procedure is identical, just confirm before buying so you receive the correct code.
Understanding the Uconnect 735N NTG4 Refresh JNAV RHP
The Uconnect 735N NTG4 Refresh JNAV RHP is an original factory-installed infotainment system developed for selected Chrysler vehicles. Designed to provide reliable audio playback and vehicle integration, this unit may also offer Bluetooth connectivity, touchscreen controls, CD/DVD playback, navigation or multimedia support, depending on the specific version.
Uconnect 735N is the Jeep-specific NTG4-refresh head unit with Garmin-sourced navigation (often referred to as "J-Nav" in service manuals) - a 6.5-inch touchscreen built around the RHP chassis. The Jeep logo appears in the boot animation.
The Uconnect 735N NTG4 Refresh JNAV RHP was installed in various Chrysler models between 2011-2013. It was commonly fitted to vehicles built on the Harman multimedia platform and is still one of the more recognisable factory radios of that period.
Typical features include:
6.5" touchscreen
AM/FM radio
Factory navigation with on-board maps
Bluetooth for hands-free calls and music streaming
USB media playback
SiriusXM satellite radio*
Steering wheel control support
Anti-theft security code
*Availability depends on the vehicle specification.
The Uconnect 735N NTG4 Refresh JNAV RHP 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 comes back to life.
Background on the platform itself is published by the official Uconnect site.
Locating the Uconnect 735N NTG4 Refresh JNAV RHP Serial Number
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 chassis label of the unit itself, not in the vehicle documents.
On this unit: Top of the chassis on a white sticker. Radio must come out; no on-screen serial display.
How to reach the number:
- Pull the unit forward with release keys (cheap online) - the wiring can stay connected.
- The serial is on the chassis sticker, usually right next to the barcode - copy it down.
- Enter it character for character - no spaces, no dashes.

Four Ways a Uconnect 735N NTG4 Refresh JNAV RHP Ends Up Locked
A locked Uconnect 735N NTG4 Refresh JNAV RHP is almost always the result of one of four everyday situations, none of which mean anything is broken.
The code card is long gone
The code card that shipped with the car went missing an owner or two ago. That is not a problem - the code is generated from the radio's serial, not from any paperwork.
You swapped the radio itself
Swapping in a second-hand radio means a new serial and therefore a new code - the one from the old unit cannot work.
The car was in the garage
Any repair that touches the 12V supply - even for a few minutes - is enough to bring up the code screen on the next start.
New battery, locked radio
Any battery work counts as a power cut to the radio. It re-arms automatically and waits for the original code before playing again.
Whichever of these happened to you, 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.
Compatible Radio Part Numbers 5
Check your radio's label against this list - any matching number means the code for your unit can be recovered here.
P68294580AA
P68294580AB
P68338220AA
P68338222AA
P68338223AA
The part number is printed on the sticker on top of or on the side of the radio chassis, usually next to the serial number. If yours appears above, the Uconnect 735N NTG4 Refresh JNAV RHP is the correct page.
Where Was the Uconnect 735N NTG4 Refresh JNAV RHP Installed?
| Vehicle Model | Typical Production Years | Notes |
|---|---|---|
| Jeep Wrangler JK (Sahara, Rubicon with nav option) | 2011-2013 | |
| Jeep Liberty KK, Patriot, Compass (nav option) | 2011-2013 | |
| Jeep Grand Cherokee WK2 (base nav trim) | 2011-2013 |
Vehicle compatibility can vary between trims, model years and regional versions. Because the same car could leave the factory with different radios, confirm your unit before placing an order.
Putting the code into the radio
It takes less than a minute once you have the four digits.
- Put the key in accessory position so the unit powers up and asks for the code.
- A four-digit keypad appears on the display.
- Key in the code, one digit at a time, left to right.
- The unit checks the code automatically on the last digit.
- Right code in, lock screen gone - the radio is back to normal.
Troubleshooting the Uconnect 735N NTG4 Refresh JNAV RHP
Too many wrong attempts
After a few wrong entries the radio stops accepting codes for a while - cutting power only restarts the clock. 60-minute WAIT timer after three wrong attempts. Keep ignition on ACC while the timer runs.
The label is not where I expected
Only the radio itself carries it - slide the unit forward and the label is right there. Top of the chassis on a white sticker. Radio must come out; no on-screen serial display.
Locked again after it was fine
Nothing is broken. Any interruption to the 12V supply brings the lock screen back. Battery disconnect, dead battery, or radio removal during a swap or repair.
I am not sure I have the right variant
Close relatives of this unit look almost identical from the driver's seat. Look for the Jeep logo on boot and Garmin-style map graphics. If the boot logo is Ram, Dodge or Chrysler, you have RHP rather than the Jeep-branded 735N variant - the unlock procedure is identical, just confirm before buying so you receive the correct code.
Note the four digits somewhere safe - they are yours for good and reusable after any power cut.

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
