Im looking around on Crutchfield for a good system that does both the Anti-Theft and the Remote start. The problem I have is that all of them seem to not have a glass break sensor. How important is this? I dont want my windows smashed in as I have had in the past. Does anyone have any good systems installed on theirs? Ones on Crutchfield are the Code Alarm CA6551 that I am looking at. I am open to suggestions!
