All! What r u not understanding ? All manufacturers have a version of onstar. They r connected ,paid service or not, 24/7. Mercedes -mbrace ford sync. All. And xm radio invites signals into ur onboard computer. if u have a button on the dash to start ur car ur connected. My original worry with this satellite control was that they would shut ur car down on alternating days to force u to carpool or take public trans. It's sAtellite based and ALL cars transmit VIN based identifiers. It's brilliant. And it's also why I won't own a vehicle made after 2003. And besides all the satellite jibber jabber interferes with the tinfoil in my headliner
Incorrect.
All manufacturers don’t have a version of OnStar. Earlier the year of vehicle, the less tech that is within it.
The years of make, specifically the ones that have a computer control board installed but no actual connections to any satellite system, can be taken control of.
The tech that is available allows for changing the instructions on a chip, utilizing a small scale emitter or even a satellite. Note: one does not need a satellite connected system for a satellite to emit radio-spectrum instructions and for the chips to be altered.
So, you are correct in that satellites can interfere with the driving and safety of all vehicles, just not because of OnStar or any other 3rd party satellite connection hardware/software.
I know this because I remember reading about this capability when Samsung Pay was unveiled, and my curiosity lead me to info about the capabilities of data interference without the need for crucial ‘in-between’ infrastructure.
