Federal agents with the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) are now adding car infotainment systems to search warrants to seek evidence in criminal cases. When you connect your phone to a car's entertainment system, it stores all of your data and never erases it. Even if you have it reset, the memory inside the unit continues to stores your data as it just deletes references to the information. Vehicle forensics companies such as Berla specialize in dumping the entirety of the data stored in the memory of the vehicle's infotainment system. Because mobile devices typically hook up to in-vehicle infotainment (IVI) systems, a whole host of information might be available, the agent wrote. That included passwords, "voice profiles and other biometric identifiers," contacts, call logs, GPS locations and Web histories. "I know that even after a previously connected mobile device is removed, much historical live and deleted data may remain within the digital storage capabilities of the IVI system," Pitney wrote. "I also know that live and deleted data recovered from IVI systems may show evidence of current or ongoing, future and past criminal activity.
