Noob.
Disabling your chime does not effect your safety you, it's called a convenience indicator.. I can see it now..."I fell out of my car because I didn't hear the chime telling me the door was open"..
And btw changing your radio doesn't have anything to do with your SIR.
I think it's a pretty idea to keep your mouth shut when you have no idea Wth your talking about.
