I have a in car MBC, but haven't installed it yet. I was told that the in car ones are not as good as the one u keep under the hood. something about taking longer for it to respond, or travel, i honestly wasn't payin attention. Anyone know about this or can give me insight I'd greatly appreciate it. I wanna know the ups and downs of having a in car MBC, to me just sounds easier to work with then having to pull over every few minutes re-adjusting it. Anyone?
