Hi, My A129 Duo, has developed a fault on automatic start up. It comes on, then a blue screen, with a warning to Format SD card, I press to confirm it, and the camera works perfectly. Next time I switch on, same thing happens every time, never used to. I have tried formatting the card, and have used the card in my other car, whichhas same dash cam, no problems, used th known good card from other camera, in my cars camera, same scenario. Nothing I do seems to work, any ideas?.
