Hi Nath, to log onto the WiFi you should hold the bigger button for five seconds for it to allow you to sync another device, it will then make a sound, the password to logon via the WiFi will be all the letters of your keyboard from Q through to P. Make sure you have the latest app etc. It’s most likely shutting down as your power is shutting it down when the engines off and it’s not the dashcam settings for parking mode/ motion detection etc. I would strongly recpmmend getting an approved auto electrician to fit it. You can buy the Q9 power pack and get that installed which works perfectly and doesn’t touch your car batteries power but charges up when you drive, it works a dream. If your in Sydney I recommend speaking to the guys at Autocraze in Silverwater they will sort it for you. Stick with it as it’s worth every cent once you get it working.

Oh thanks for your response. I had changed the memory card yesterday and it works fine.
