Open NNG File

The NNG format files are data from the Pioneer AVIC navigation unit.

The NNG file extension is primarily associated with Pioneer AVIC Navigation devices and is used for internal purposes.

The NNG file contains the serial number of the navigation device and is required for synchronization purposes with the Poi Con Speedcam Service, which is a database of POI points compatible with most GPS devices on the market.

Pioneer AVIC devices are multifunctional devices for vehicles that can play audio, video and have built-in GPS navigation functions. One of the functionalities that some AVIC models have is voice control.
