Why I need a GPS?
The GPS module can record your speed and route data in the video file allowing compatible viewers to display the data on playback. It will also keep the camera' s clock synchronized with GPS time so that the video files are correctly time stamped. It could also be a way to tell your dashcam to automatically get into/out of parking mode by speed data (if you didn' t use the VIOFO HK3 ACC Hardwire kits for parking mode).
