Vehicles with an Audio-Video Navigation (AVN) system have become another source of potential digital evidence. The AVN systems in modern cars retain information and event data from mobile devices connected to the car’s infotainment module, and navigation data in the form of tracklogs. These data provide a time history of a car’s geolocation that may be used to investigate an incident involving an automobile or reconstruct a crash. There has been little research into what types of user artifacts can be found on the AVN systems, and whether the AVN systems provide more vehicle event information than the connected mobile devices. For this study, we used the AVN system of a KIA NIRO EV vehicle for digital data acquisition and analysis. We have found that the AVN system provided some amounts of user data (start log, favorite routes, last destination search history, etc.). The acquired data and analyzed results can serve as basic digital evidence for vehicle forensic research.
