Sir i am confused. i will install front cam for sure but i am thinking to install steering controls too (which has both side buttons) and will give signal to front cam from one of the steering control button to get an ease. It is a bit tedious to first click to main screen, go to the menu, scroll to next page then click to AV in icon . I know my father wont do that and front cam is then no use.
There is a mode button on steering controls which will serve my purpose. It will give the signal to AV in port and front cam will start operating.
