Does the mirror have ramp-up beeping for RDs that are hooked into it? If so, how good is the ramp up? I'm getting the mirror no matter what, but I do love the V1's ramp up and having to look at the V1's concealed display to determine signal strength takes my eyes off of the road unnecessarily.
EDIT: Is there a button on the mirror to mute both voice and tone alerts? There are a few places by me where I need to mute because of falses but I'm driving 70mph so the FAST system won't really be practical.
