Why is it that the Redline is said to be harmed by the interference of a V1 but not vice versa. If the Redline uses a magnesium case, it is supposed to be shielded. Electronic shielding is often done this way. So why does everyone say the V1 interferes with the Redline/STi D given that ALL of these have magnesium cases? I would think the concept of a 'stealth' detector means it really is shielded so how can it be harmed by another unit?
