Adrian You need to go to the Top Menu. Scroll through settings to "Car Mode" icon on Page 2/2. Select this with the Start button . The car icon should now be on-screen. Press "Down". You get the DashCam Menu. Turn DashCam "On" and set Loop Recording to 3/5/10 mins. Also set Power On Record if you want to Start when you start the Engine (connect car charger). This should overwrite on a Oldest-Out basis.
