Recently, in-vehicle infotainment (IVI) systems, also called car audio video navigation (AVN) systems hold a wealth of digital data valuable for forensic investigations, encompassing navigation history, call logs, and Bluetooth connections. They serve as central hubs for entertainment, communication, and navigation, storing crucial evidence for accidents, thefts, and cybercrimes. Therefore, forensic investigations of IVI systems are becoming increasingly important. In this paper, we conduct a forensic analysis of an Android Jellybean-based AVN system installed in Kia K5 2017. We first efficiently collect system logs as well as navigation logs using the log menu of an engineering mode provided by the car manufacturer company. Therefore, our data collection method does not require a chip-off technique or rooting of the AVN system. Next, we analyze the collected logs systematically and the differences between the two types of log data. Our forensic investigation method can provide insights into occupant activities and reconstruct events leading to incidents and car crimes.
