In-car entertainment, or infotainment, used to be synonymous with the original AM car radio, as infotainment is known for delivering entertainment and information to vehicle occupants. Owing to today’s advancements in technology, infotainment has evolved. Utilizing modern hardware and software, infotainment systems assist vehicle operators by making data more available, such as a backup camera adding a view angle or an in-car navigation providing directions. The first infotainment systems were not much more than a pathway to play music through the vehicle’s speakers; however, they have now grown to be versatile, offering hands-free calling and even reading text messages aloud. A key identifier for current infotainment systems includes an audio interface constructed of a touchscreen for the use of radio and music, , climate control, navigation, and as a connected phone interface. There is a substantial variety of infotainment systems on the market. Each manufacturer has their own unique system, along with different versions over the years, showcasing different features and distinct elements.
Infotainment systems can store data relevant to vehicle collisions that help engineers analyze the events leading up to a crash. An infotainment system stores GPS data not only associated with the route of the vehicle, but with events such as doors opening/closing, light activations, and more. Infotainment data is often timestamped and defined with geolocation data.
While different types of data are available to be retrieved from infotainment systems, there are some obstacles. For example, with the right forensic tools, text messages can be extracted from an infotainment system, but sometimes they only include text messages that were received, not sent. The main driver for what data is available is the vehicle make. Ford’s infotainment systems differ from Toyota’s, Chevrolet’s, etc. Each system is similar, but each may store different data.

Even though cell phones are physically small, their data storage capacity is quite large. The infotainment system storage capacity in newer cars is also large and includes data from cell phones if it has been connected via Bluetooth or USB. An infotainment system refers to a vehicle system that provides entertainment and information to the end user. The systems include audio and video interfaces, touchscreens, and other features to enhance the user experience. Most newer vehicles are equipped with an infotainment system that assists users with various tasks such as hands-free calling and a rear-facing camera for reversing.
