Enabling reverse camera while cruising

[j1m4kos]

Hi
Is it possible to access the reverse camera while cruising? I tried using this menu but no luck http://pleasedonttouchthescreen.blogspot.gr/2012/10/toyota-touch-hidden-menu.html
Has anyone tried it ?

Typically to do it you have to add a switch to trigger the reverse signal to the head unit. You would also need a diode to prevent feeding the signal to the lights, where you would scare people behind you when you switch it on.
