Android 6 battery drain 2-din gps

[farmeroz]

Hi,
I post here for info.
I have been installing an Erisin (Chinese) 2-din 7" display android 6 GPS/headunit system.
For information the UNSWITCHED (yellow) drew 0.75A at all times and the switched (red) took 30mA (0.030A) at all times with no speakers in use. Clearly this will cause rapid battery drain.
Switching either one resulted in a reboot (ie showed the boot screen on re-connection, same time to boot).
This is a fault. I intend to connect both to the switched supply and see how I get on. This will at least solve the battery drain problem. I may report later if I have further info.

Hi,
please first tell me your order number in amazon or buyer id in ebay,Pumpkin or AliExpress so that we can confirm more information about your unit and provide you positive solutions.
Normally,after you install the car stereo,the yellow wire constantly get power.After you turn the acc off/plug out the car key,the red wire will outage but the yellow wire will still get power with micro circuit.
Regards
