The *.HAFMMA file extension is primarily associated with navigation data files used by Hyundai and Kia vehicles equipped with the Mobis AVN (Audio Video Navigation) system. These files contain map data, points of interest (POIs), and other navigational information essential for the system's operation. The specific internal structure of *.HAFMMA files is proprietary and not publicly documented. It is designed for use within the Mobis AVN environment and is not intended for direct manipulation or use with other navigation systems. This file format is classified as GIS data.

HAFMMA file format details:

To view or edit HAFMMA files you need to know the file format, because it determines how the data in this file is stored. The file format can be determined based on the file extension and the signature (the first few characters of a file). However, different programs can use the same file extension. Furthermore, a file extension can be renamed incorrectly and double-clicking on it will then display an error when it is opened. So you need a detailed analysis of a file to find out the format and the associated program. Below you will find our evaluation of the HAFMMA files:

HAFMMA is rarely used as a file extension and predominantly uses a uniform format. The two most common formats are as follows:

98% of all HAFMMA files start with the magic bytes FORMAT_VERSION_01.0, which are always the first bytes of this file format. These files are binary files, so they do not contain text, but only cryptic characters. The files are often between 470 KB and 70 MB in size. This file type is based on cutting-edge technology. The files contain the following words: DATA, FORMAT_VERSION_01.04.01 and FORMAT_VERSION_01.04.00. Files like these are sometimes connected to image, voice, symbol, rendering, unique, admin, general, landmark, driving and course.

All other HAFMMA files (2%) have different formats. Files like these are sometimes linked to guideimgres, extsymbol, junction, model, theme or view. If you want to find out which format your HAFMMA file belongs to, just click on the button "Choose your .hafmma file to analyze".
