I was under the impression that On star and 'the Black Box' are two entirely different things.
There are some really good things about On Star technology, too. If my Grandchildren had been kidnapped and were being transported in a vehicle with On Star, I'd think it was the most fantastic gizmo in the world.
On Star and the black box ARE two different things, I was trying to point out that if you enroll in On Star you are basically signing on to give up your privacy, while with the black box you are giving it up involuntarily and for some without that knowledge.
