Hi, I have a compustar unit installed in my car, reservation mode works fine during the day, however at night it doesn't seem to work properly.

I set the reservation mode, walk out of the car, close the door, turns off engine, however since at night more then my dome lights come on, it doesn't do the last step, where it arms the alarm/locks door.

It just turns the engine off, and that's it I have to manually lock/arm the alarm.

Was wondering if that's how it is suppose to work or am I missing something.

During the day, it works fine, reservation mode, get out of car, car turns off, dome lights go off, car arms/locks door.
