Courtney Lancaster gave this talk at Shmoocon 2014 outlining the types of information available from vehicle infotainment systems “This talk will take an in-depth look at infotainment technologies and how to forensically acquire the data associated with the functionalities that exist across various manufacturers. Furthermore, we will cover the challenges of conducting digital forensics on an actual car, both physically and logistically.”
Boring presentation lacking the juicy details.
