just saw my friend's 360 cam on his new car and its soooo cool. I feel like getting myself a 360cam module too, or failing that, a front sensor too ( already have back sensor).

so my question is

1) if my car doesnt come with 360 cam, can i install it later?
2) if installing 360 cam is impossible for cars that dont come with it, is it possible to install a front sensor , like the reverse parking one but in front instead ?
3) how would they do it ? would they drill a hole on my hull to install it?
