My vehicle is older than 2008 and Raven's displays keep turning off

Raven was designed to communicate over CANBus.  Car manufacturers created an OBD standard for light duty vehicles in North America to adhere to the industry standard from 2008 to present.

Your pre-2008 vehicle will exhibit behaviour that makes it appear that Raven is in parked mode because it is unable to determine if your vehicle's engine is active. 

The displays will turn OFF when you are not moving for longer than 5 minutes because it now requires the use of the accelerometer to determine that your vehicle is driving.

Please be aware that when the displays are OFF, no video is recording and the WIFi is disabled because Raven was designed to communicate over CANBus to know when to remain active.

Once the pre-2008 vehicle is in motion it will reactivate the displays.  Each pre-2008 vehicle will exhibit different behaviour since there was no OBD standard until 2008.
