Atoto A6 Pro, ignition power cycling problem - Android Head-Units

Hi all
Just picked up an Atoto A6 Pro for my 2014 CRV Touring.
Everything is wired correctly and I popped the unit in.
I am experiencing an issue where the device will not power cycle unless I press the power buttons on the unit itself.
No wake on ignition and it does not turn off with the key removed either.
I verified power is properly reaching the unit with a multimeter (checked ignition power and constant power).
And now I have tried reversing accessory/ignition power on the radio harness. Now the unit will turn on/off with ignition BUT it does not seem to receive any power when ignition is off. Causing it to lose stored time, and to slowly reboot each time the ignition is turned on.
Does anyone have any experience with this?
thanks

Power consumpition Joying DE-JY-UM124N2

Hi,
I'm testing the unit at the moment at home before I put it in the car.
I wanted to know what's the power consumption is when ACC is off. Joying says it's 11 mAmp.
The unit goes in a sort of sleep mode than, when I switch on ACC again after 30 min it takes about 3 seconds to wake up.
I have no CanBus.
I connected my multimeter between the Constant B+ wire to see how much power the unit takes when I should leave the car.
When I set the multimeter at 20 Milliamperes it displays 00.59 .
My question is, how many milliamperes is this ?
Thanks .

xtron PR78OLO-s opel corsa D not turning on at ignition after a while of use.

Hello
I recently purchased the PR78OLO-s and i love it. Thank you for such a beautiful product.
I have used it for a few days and i have run into a small issue.
Sometimes the unit will not start on power on. Even holding the power doesn't work.
>
I will have to unplug the iso cable and plug it again then it will work.
Why does it do that?
Xtron tells me to Cut the ACC cable from the canbus and use the ACC cable from the ISO instead, and connect that to the positive end on the cigarette plug.
But in my head i think that sound weird. It works fine for a day or two. Then all of a sudden it won't turn on at ignition. Have to unplug the ISO and plug again.

Help needed! Did I just buy a brick?

Long story short, I just bought a 10.25" Android HU used for my BMW F20 but the owner didn't give me the power harness. Seller disappeared so I needed to figure out what unit it was in order to try source the harness.
I had read in BMW forum that the unit can be turned on with a 12V power supply connected to 2 pins on the back but when I did that, nothing happened. I could see a red led on the board turn on, stay on for about 10 sec, then turn off.
I had tried to hold the reset button when power on but it's still the same. I had noticed that when I pressed the reset button, the red led turn off, then turn back on.
Did I fried the screen or did I buy a brick? Thanks a lot!
