This is NOT examining the EDR or (Event Data Recorder) or the Black Box, that is normally done with a Bosch or other branded system relating to only the EDR.  The EDR is traditionally the primary source of data for crash reconstruction.  The data from an infotainment can recover some facts that can assist in crash reconstruction and not available in that EDR download.
We use the only forensics system on the market from BERLA forensics. We are one of a handful of private entities that have been given access to this forensic software, hardware and system.
There is Nothing else than can do this forensic exam.  The majority of OEM brands are covered.  Sorry No Tesla.
