Since the forensic approach to digital devices began, evidence subject to digital forensics has been steadily increasing. The reason is that general devices are equipped with storage media on their operating systems, and they are becoming the subject of digital forensics. In particular, electronic and autonomous driving performance is rapidly growing in the automotive field. Since these functions are installed, various user convenience functions have been provided. In the automotive field, various parts are becoming electronic; however, the audio, video, and navigation(AVN) system that directly connects with users to exchange data is the most important in the digital forensic field.
