Theme, Color, Dashboard changing in Z3 - HD3-II

[RastaRevolution]

Hello,

 

did anyone knows, if it's possible to change the color of the dashboard or the theme?

I didn't see any option in the manual or menu.

 

I don't like the blue color, i will change it in green or red.

 

The Theme/ must be on HDD, did anyone knows the name of the files to change the color?

Is it possible to make something like a new skin for AVIC Z-Series or european HD3-II?

 

Thanks in advance for the answers!
