I am glad I installed this unit in my car it is a life saver.
I took the full package with the text to lock/unlock my doors and automatic immobilize, now anything that happens to my car I get a text and in the event of a break in the immobilizer prevents the car from starting or a carjacking, I can remotely have the car shut down from any of the 5 administrators that I have chosen. Best of all is the FREE App that all I have to do is press a button on my phone and the command is sent to my car. 18 months warranty means that they believe in the product and best of all it cost me less than 100 per year.
