What Is the FIAT 637 VP2 NAFTA NAV Radio?
The FIAT 637 VP2 NAFTA NAV is a factory-fitted Chrysler audio and multimedia unit. Alongside everyday radio and audio playback it may include touchscreen controls, Bluetooth, CD/DVD playback or factory navigation, depending on how the vehicle was specified.
Continental FIAT 637 VP2 NAFTA NAV is the 637-series NAFTA Fiat-platform Uconnect with built-in navigation - touchscreen with maps, SiriusXM, North American tuner. Carries the Fiat-branded boot logo.
The FIAT 637 VP2 NAFTA NAV was installed in various Chrysler models between 2017-2021. It was commonly fitted to vehicles built on the Continental multimedia platform and remains one of the more recognisable factory radios of that period.
Typical features include:
AM/FM radio
Navigation built in, with factory map data
SiriusXM satellite radio*
Bluetooth for hands-free calls and music streaming
USB input for music playback
Steering wheel control support
Anti-theft security code
*Availability depends on the vehicle specification.
As with other Continental factory units, the FIAT 637 VP2 NAFTA NAV locks itself when power is lost. After a battery disconnect or a workshop visit the screen will ask for the original security code before any audio returns.

How Owners End Up on This Page
A locked FIAT 637 VP2 NAFTA NAV is nearly always the result of one of four everyday situations, none of which mean anything is broken.
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 - normal, not a fault.
A unit from a breaker
A used unit from a donor car always arrives locked, and the code from your old radio will not fit - the code follows each radio's own serial number, so order it for the serial on the REPLACEMENT unit.
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 battery change
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.
All four roads lead to the same solution - read the serial off the unit, enter it above, and the original code comes back instantly.
Reading the FIAT 637 VP2 NAFTA NAV Chassis Label
The code is generated 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: Chassis top label. Removal required.
Getting to the label:
- Bring the radio out of its slot; release keys do it in seconds and nothing needs disconnecting.
- Find the printed label on the housing and read the serial off it - it sits near the barcode.
- Copy it into the form precisely as printed; the checker catches any typo before payment.

Entering the code on the FIAT 637 VP2 NAFTA NAV
The code goes into the unit itself, not into the car's menus.
- 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 its usual self.
Things that can catch you out
Too many wrong attempts
After a few wrong entries the radio stops accepting codes for a while - cutting power only restarts the clock. 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. Chassis top label. Removal required.
The radio locked itself again
Expected behaviour: the security system trips again whenever power is cut. Loss of 12V supply.
I am not sure I have the right variant
Close relatives of this unit look almost identical from the driver's seat. Nav variant of the 637 NAFTA family. Non-nav siblings return "Feature not available" when tapping the maps tile.
Note the four digits somewhere safe - they are yours for good and reusable after any power cut.
