I have a new vectra C and the alarm is not sensitive at all, i can boot the wheel or bang on the window and it wont go off at all, any know if the sensitivity can be altered?
Also, i managed to make the alarm go off by when i jacked the car up. But the alarm was more like a sqeel than an alarm. I heard a SAAB Alarm recently and i was really loud, im pretty sure the alarm on the saab uses the HORN on the car as the alarm as the noise was the same. Does anyone know if the vectras alarm can be hooked up to the horn so the alarm is louder?
