## How to identify NTG5.5

One of the easiest ways to identify whether your car is NTG5.5 is to use our [Car Lookup](/guides/car-lookup) feature.

### Car Lookup

An interactive vehicle lookup is available on the canonical guide page.

### Video Tutorial

A generation-specific video walkthrough is available on the canonical page.

## Purchase a Map Code

Follow our guide [here](/guides/map-code), or use the form below once you've created your USB.

Enter your VIN in the map-code flow to confirm the compatible navigation system, region, and version.

## Region Compatibility

**Important Notice for Korea, Southeast Asia, and Japan Vehicles**

If your car has a region of **Korea, Southeast Asia, or Japan** (including imports from these Asian countries), and you want to migrate to a navigation from a different region (such as Africa/Middle East or Europe), **you cannot use our service** - the update will not work.

**Before purchasing a map code, you must:**

* Change your head unit's region first by finding a service online, or
* Replace the head unit entirely

**Refunds will not be granted** for region incompatibility issues if you proceed without addressing the region change first. We provide clear warnings in our code generation dialog and guide pages about this limitation.

## Common Problems

Here are some common problems you might encounter when purchasing a map code for your NTG5.5 car.

### USB Stick is not valid, even though it is correct

This is likely a region error and **ONLY** occurs with Korean and Japanese cars (even imported). If you are unsure of your car region, please use our [Car Lookup](/guides/car-lookup) feature to verify your car region.

In cases like this, you will need to consult a service to change the region of your head unit to your desired region. Contact us at [contact@mbretrofit.it](mailto:contact@mbretrofit.it) for more information.

### Installation was unsuccessful
