V1/S1. No question.

V1 shows multiple threats AND where they are (FSR). S1 mutes the stereo when there's a threat.

This setup has saved by a$$ twice in the last week.

Only drawback is there isn't a place to conceal the V1 in the X5 (don't know about the X3) w/o losing rear and/or laser detection - at least none that I'm aware of.
