on mine it is working, kind of nice touch, headlights on, the wipers come on automatically, and i even made to have sunroof close when the auto wipers kick in...

Could i live without it - I sure could... after all, i live without the after burners, the jet thrusters, the gun mounts, the refrigirator in the backseat... and many other things that do not exist... I don't know about them, I am totally fine...
BUT I WANT MY iPHONE!!! AAAHHHH!!!! i am spoiled... i want the toys!!!!
