You say that vent is for air to escape the cabin or trunk? Ok, this makes sense... but where does it come from in the cabin and in the trunk?
Yes, I have seen the crash sensor behind the radio. I thought this was only the control unit or something for it. How can it be so sure there's been an accident when it's not mounted close to the outside of the car? And is this sensor for both front airbags? If so, still how does it know which one to set off?
