Did the RX330 come with a factory alarm. The car I have in Australia is the top of the range RX330 here (there was a Sports pack and a Sports Luxury pack only, I have the Sports Luxury with Nav, ML, Sunroof, etc. etc.). I know that there is an immobiliser and there is a security flash on the dash. I thought I would test the alarm the other day, by opening the window, closing the door and then locking via the remote. I reached in and opened the car door and nothing, no alarm or anything. I would suspect that either there is no alarm and just an immobiliser or have I missed something?
