I'm having an issue with my SG9663DC where it will power up when I turn on the car but then shut off after about 3 seconds. After this happens I can't turn the power on and buttons don't respond at all. I've also tried it without the SD card, without the back cam and GPS plugged in. I did try it with another power cord in my house and the same thing, powers up for about three seconds and then just shuts off completely.
Any ideas for how to troubleshoot this?
