Morgan says that hacking a car's key fob to make a car beep but not lock, is easy. Actually, it would require one to hack the internal computer of the car. If the unsub hacked the key fob, the car would either beep and lock or do neither.
Morgan uses a touch screen in the Hammonds' BMW to look up the driving history. BMWs do not use touch screens; the screen is controlled by a knob in the center console. Also, the graphics on this screen do not match those of an actual BMW.
The Michigan license plates shown on the vehicles are blue with white lettering. Michigan stopped using that plate in 2007 despite the fact that this aired in 2013.
Reid points out that the unsub found the victims through their GPS data, which is supposedly sent to the car companies for research purposes, and that he knows this because he reads the agreement that appears on the navigation screen that the driver must agree to before he/she can use the system (and supposedly, no one else reads it). This isn't true. The message that displays and that the driver must agree to before he/she can start using the GPS is actually a safety warning. It reminds the driver to not be distracted by the GPS and to obey traffic laws, and that safe operation of the vehicle is the driver's responsibility.
There are license plates on the front of the victims' cars, but Michigan only requires rear license plates.
