Hello MP3car, ive been usin my car pc for about 7 months and ive been looking into using my RS232 I/O controller with 8 relays and 4 opto inputs to controll various things within my car.

my alarm system has various triggers and expandable features, one of them is a 12v line that seems to activate the alarm and central locking.

my windows are already controlled by the relay as well as the boot release.

has anyone looked into the idea of using a carputer to interface with the alarm?.
