Basically, the forensic exam of the infotainment module is non-destructive. No it will not destroy a car.
Knowing ahead of time the year, make, model, VIN of the vehicle to predict what data may be obtainable and how long the download could take. It can also determine if the non destructive method is a possibility.
If not accessible in the field, some module can be broken down to a chip level or a “chip-off” forensic exam. The chip off is destructive process. This would require replacing the control board within the infotainment module in order for the vehicle to function normally again. Worse case is that the radio control module would have to be replaced.
With the full vehicle identifying information beforehand, most of the time we can predict if a chip off is the only way to access the data. Only a small percentage of vehicles have to resort to this. Also the physical condition of the vehicle may affect the in field acquisition. If it has been destroyed by fire, chip off may be the only resort.
