Hey all, Just a few questions as I think about pulling the trigger on a s 85D with tech package. 1) Does it have an alarm system? for example if i get my window smashed does it go off? does the app do anything with the alarm if there is one? or do I have to install a system aftermarket? 2) mirrors...do the side mirrors and rear view mirror automatically have dimming features? i have that on my current BMW and love that. basically that and heated steering wheel makes for a great drive at night. thanks!
