In the automotive industry, vehicle technology continues to advance to satisfy consumer driven functions. Whether the expectation is increased safety, comfort, or options, in-car technology demands are on the rise. One of the measures taken by automakers to mitigate these demands is the implementation of state-of-the-art infotainment or telematics systems. Although there is some overlap between these two systems, such as sharing the same visual display monitor, there are functional differences. The basis of infotainment involves the combination of entertainment and information, which may be obvious given the name “infotainment”. Common infotainment functions include GPS navigation, listening to music, and Bluetooth phone operations. More recently, infotainment systems have gained the ability to store cell phone related data when tethered by USB or Bluetooth. Infotainment systems also allow drivers to link their phones through integration software such as Apple CarPlay and Android Auto.
Vehicle telematics merge telecommunication and informatic functions. When comparing telematics and infotainment, the most notable difference is that telematics utilize two-way communication. The communication provides a platform to send and receive data. The exchange of data is necessary for features like vehicle location for navigation, collision reporting for police or insurance providers, and remote vehicle diagnostics. Telematic systems can be built-in (onboard) or aftermarket. Built-in or OEM telematics are commonly subscription based such as OnStar by GM. Companies are beginning to use aftermarket plug-in telematics to track their vehicles and how or where they are driven. The devices are plugged into and powered by the diagnostic port usually located in the driver’s footwell area. Insurance companies offer similar devices to track driver behavior to possibly yield a discount on premiums.
Regardless of the type of system, infotainment or telematic, accessible data is potentially stored in the vehicle or in a cloud. The data is not only obtained for insurance discounts or safety related purposes, but also for incident related situations being investigated at a forensic capacity.
