E-PRANCE Mini 0803 Ambarella A7LA50D Chip Full HD 1296P, GPS Logger, Inbuilt 8GB Memory with 32GB Memory Card
I recently installed in my car.  After only three weeks use it has begun intermittently begun making an audible pulsing sound.  And it gets extremely hot and stops recording although video display works.  After disconnecting from power and cooling down, it seems to operate for a few hours normally, then pulsing sound and heat are experienced again.  Very disappointed.
