ok I have just tried another one of these G1W-s dash cams for my Audio problems. many will not realise that if you have yours recording permanently once you reach the end of your Card and its starts to overwrite. you loose audio on all your next footage and any after. only way round this is to turn the camera off then on then on each time before it starts re writing at the point where you have turn off and on, if that makes any sense? most people will not have noticed this as your camera is ignition live so it will automatically turn your camera off and on with the key, so there fore will sort your audio issue out with out you knowing you have had one in the first place. is there any chance someone on here who can run a test with it powered on to fill the card up and see what audio test you get on the next re write sections please. the two G1W-S cams are acting the same from different sellers. so I think there is a fault within these cameras that people have yet to discover like I have just done.
