Many late-model BMW vehicles are equipped with an NBT Evo infotainment system. This system is seen in BMW vehicles in all global markets. Like infotainment systems from other manufacturers, this system records data elements that can prove to be key evidence to investigators of vehicular incidents. This system records timestamped tracklogs that consist of GPS coordinates paired with date/time data. These tracklog points, however, are not recorded in regular intervals. Testing of an instrumented BMW 430i was conducted in and around the Bruntingthorpe Proving Grounds in the United Kingdom. The test vehicle was instrumented with a Racelogic Video VBOX Pro. Data from the instrumentation was compared to the data acquired from the BMW by the iVe Ecosystem from Berla Corporation. The accuracy of the GPS coordinates recorded in the BMW tracklogs was determined by computing the distance between the recorded BMW data and the reference instrumentation data.

Data acquired from vehicle infotainment systems has continued its growth as key evidence in vehicle-related investigations. The accident reconstruction community continues to actively pursue digital data from vehicles to be used alongside traditional forms of physical and electronic evidence. Some of the vehicle infotainment systems that have provided valuable evidence for several years are now being updated by their manufacturers. One such system is the Ford SYNC Generation 3 (SG3) system. In 2019, Ford began installing an updated version of this system that included changes to the SYNC module. The new system, referred to as SYNC Generation 3, version 2 (SG3v2) is outwardly identical to the original SG3 system until the module is physically removed from the vehicle. Ford has released the new module globally and it has been observed in North America, Australia, the United Kingdom, and several European countries.
