DBL car audio does an alarm system has a sim etc.... also gps tracking, you can set perimiters eg. speed of 70kph and 2km from a set destination and you get notified if the boundaries are crossed. an emergency function (notifies 3 people (plus you) if something happens and sends them the location, tilt sensors, hidden microphone and the works. It is good, it is the alarm i will be getting soon.
The remote immobiliser is illegal, it is due to a) accidents and b) a lot of insurance companies wont cover you if it is stolen and hit the remote immobiliser and it kills the engine somewhere eg. middle of an intersection and they get wiped out.
that is why the EVO no longer has the remote immobiliser. (Think it was evo 9 that had it)
