The function of IGLA2 is the same, but a siren sounds when the door is opened, and it is a model with a built-in two-stage shock sensor and a warning and alarm function to quickly drive away thieves. When IGLA is installed, a closure function that automatically closes the window and a program that blocks key duplication are added. IGLA2 is a standalone model that only controls engine start, so compared to that model, this model with an alarm protects your car even more.
