It's a bit complicated
U need:
Obd2 Reader - ie. ELM327 bluetooth
Smartphone - Android or iOS
TrackAddict - software / datalogger
GoPro or other camera
Could be sport 10Hz external GPS
RaceRender3 - pc/mac software to generate final vid with data overlay.
So it looks good?
So - on track record data with TrackAddict (connecterd with obd2 Reader and GPS internal or external).
After wars download everything (data files and video from camera).
Synchronize all in Racerender and U have it
