The Security group consists of a retractable soft cover for the Cargo area of the Compass.
Security Alarm is an anti theft device that has some engine immobilization features in case of tampering. It also works in conjuction with the Driver Convenience Group. For example if the systems detects any tampering and an unauthorized person got into the vehicle and if it was parked outside the garage, they will not be able to open the garage door using the Universal garage Door Opener.
It is only $200 CDN - I got it, not because I wanted it but the vehicle I wanted already had it.
If you are in the Toronto area (where Compass' with the nicer options are hard to comeby) I wouldn't let it hold me back
Hope this answers your question
