⎜ Overview of Operation ⎟

Recorded data is saved as Runs. Each Run starts when the vehicle exceeds 20MPH/33KPH and ends when the vehicle is moving slowly. The run includes several seconds of data before the recording trigger speed is reached. This way the start of an auto-cross run is included.

⎜ External GPS Modules ⎢

Due to limitations of the built-in GPS, the data may suffer from inaccuracy. An external GPS module is required to record accurate data for high speed driving events.
