Thread: NEWBIE [and THE OTHERS :)] PROBLEMS with NG INSTALATIONS

Hi, Sorry i didnt want to ask in wrong place so i am asking here
I have always used default skin (basarsoft, now igo nextgen israel)
My unit is a chinese mtcb android head unit with 5.1.1
i have wanted to change a few things, not sure if it is a skin or other mod, or if it is possible

1) change so when in navigaiton and press on map it does not select a new destination during

2) change so when i press back button, it exits navigation (not exit app)

3) change so there is a button for new navigation (rather than menu-<new route)

4) maybe a button for delete route while navigating

are these things able to be done? is it skins or something else?
thank you in advance
