PUMPKIN CAR STEREO SUPPORT CENTER

Hello I have bought this Car stereo:27-AQTU73-DE-A
It has Android 6.0.1. Basically it does all I need but I still have some Issues.
1. If I turn off my car and later turn it on again there is either the app Music/Radio/Video starting at random. My old unit started the app that was active before being turned off.
2. The Unit gets quite hot to the point where it shuts down automatically. After using it for like 30 minutes.
3. Also the Car stereo I had before was a lot more customizable like changing the apps in the bottom line of the screeen or removin the widgets from the home screen. This Unit seems to have a custom Launcher. Is there any way to deactivate it?

Hi,
Could you please first tell us you order number or buyer ID?
1. Please check the red and yellow wire position of our power cable, if their position is reverse, then the unit will loose the memory.
2. The point of the unit is used for helping rejection of heat from the interior of the unit. Sorry for hot trouble caused.
3. It's the factory default design, different kind units have different screen layout, so there is not a way to change or deactivate it.
Regards
