AC Question

Hi,
On my car android system (android 4.4 i believe) not all setting option are available.
I am trying to create a full back up of the system.
I tried the recovery mode - it is not the usual recovery mode - it has buttons to push on and they all give various option for updating. No option to restore or backup. On option though is to update the recovery mode itself.
I tied enabling developer mode but pressing the "build #" many times did nothing - perhaps it was disabled by the manufactures.

Is there any way I can enable the usb debugging/mode?
If not then how can i make a full back which i will be able to later restore as an update for the system since this is the only available option in the recovery mode?

Thank you!
