Nowadays the most of vehicles are equipped with different types of on-board computers.
Usually such devices have navigation systems, cell phones, radio etc built-in.
From digital forensic standpoint memory chips from such computers may be a real treasure trove of information. When the high profile case comes to the lab, even one phone number or contact may completely change the story. As you may know car infotainment systems have proprietary architecture so the easy access to data using standard interface is not always guaranteed.
This is where chip-off technique is the only way to pull the data out of the device. These cases can be solved by eMMC-NAND Reconstructor.
