JW every time I have to install a new one it seems there are more things added. I always think of Jumptrout he seems to know about everyone of them.I have to read and reread the directions about 3 or 4 times. I really hate hearing from the customer, I bought mine because my friend just loves hers,it programmable. And I love the way it lights up ? When can you install it. They said at the store its really easy??
