Opening NNG files

Did your computer fail to open a NNG file? We explain what NNG files are and recommend software that we know can open or convert your NNG files.

What is a NNG file?

The .nng file extension is most commonly used by the Pioneer AVIC navigation unit. These files contain the serial number assigned to the associated navigation device. The NNG file is used to synchronize the Pioneer AVIC unit with the Poicon Speedcam service.

Software that will open, convert or fix NNG files

Unfortunately we have not received enough suggestions for software that can open NNG files yet.

Try a universal file viewer

I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
