Hello, just got my 2010 Mazda 3 GS yesterday! I have a quick question about the "anti-theft alarm system", in the Trim level comparison chart on mazda's site it says the GS comes with "anti-theft alarm system", is this a normal alarm system that is supposed to go off and make a sound or do I need to get some other alarm system that actual makes a sound if someone is trying to break into the car? If it doesnt make a sound, what does it actually do? If it is something I actually need to add to make a sound, what do you guys recommend and about how much is it gonna cost me?
Thanks in advance!
