Ok, so I'm moving to an apartment from a house. Long story. Anyway, The apt complex itself is very nice, even gated. The problem is the surrounding area has some very low income housing. Not to stereo type, but I drove through there, its ghetto. So, since i have put the time and money into installing a nav/dvd HU and some subs, I'm now looking at getting an alarm. Any recommendations? Does the 05 already have a factory security system? I haven't tried to open the doors after they have been locked. Any help is appreciated.
