ZX803 model AllWinner chip 8" Android 4 capacitive screen car head unit topic

Hello everyone, I purchased this unit (VW submodel) few days ago. Picture attached.
it works great.
8"
1ghz cpu,
1gigs of ram,
4gigs of flash + microSD,
capacitive.

Does anybody have the unit with same chipset so we can exchange some info? For example, I can't find an entrance to hidden menu that was presented to me at first boot,
I don't know how to restart the unit, and I have a slight issue with car battery draining.

To be straight on topic, I have modified stock radio application to be more... ... presentable :) It was terrible, colors were out of this world :)
This unit came rooted. So I could easily replace the stock radio app.
If somebody needs it just let me know.
Now it looks like this:


Thanks!
