## Need a map license key?

When you update the navigation system from a USB you made yourself, the car asks for a map license key before it installs anything. [Need help finding your VIN?](/guides/finding-vin)

Follow our [map update guide](/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.

## How to find your NTG version

The fastest check is our [Car Lookup](/guides/car-lookup). It reads your data card and reports the NTG version.
