Every time I open my sunroof I have to hold the button down until I get the desired amount of opening needed (or every time I want to close it); Now this is OK if your car is not moving, but what if you wanna close your roof while you are driving, its kinda hard to focus on the road and get the sunroof to seal right (so there is no noise); is that the way our sunroof works? Because in my previous car (celica GTS), all you have to do is push the button once. Your response is greatly appreciated. Thanks!
