Its a definite violation of privacy.
The info on the black box can also be used against you by the manufacturer to void your car warranty.I didnt realise what was on the thing till I took a new truck to the dealer and he hooked up his laptop.
Those who pay for onstar are giving up their privacy and paying for it, If thats what they want to do thats fine , but they should realise what they are paying for.
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.
You can buy software and a link cable that will do some pretty kewl things with your OBD II interface.
What with location services and car black boxes, I'd be sure to have my phone and car corroborate my alibi if I ever were to really need one.
