How do I get a first person view, driving in Grand theft auto 4 on xbox360?

I was playing my son’s X-box Grand theft Auto 4 and after a number of failures and spectacular crashes, accidently mashed a combination of buttons where I had a view from behind the wheel! That made driving a lot easier! I’ve not been able to duplicate the feat which is very frustrating for a rookie game player. (even though I am 50 lol!) Does anyone know what I did to get that view while driving?
