My VX was broken into for the second time in two weeks.
The first time the bent the tab at the top of the window, pulled the top out and unlocked the door. The worst part was that I heard the alarm and but by the time I got to the window they were gone, and so was my sub.
The second time they broke my window and destroyed the dash to get my head unit. They also stole my other sub.
I will not trust the stock alarm again. If they only break your window, it will not sound.
