That system is so old it's amazing it's even still on the air. It's essentially RDS but with other information onboard.
Maybe they are keeping it alive for a reason. it was upgraded in 2015 to 2kbps from 1kbps, graphic capabilities were added and sms support if radio supports sms. It would be pretty easy to embed a computer control feature to shut an engine off if they chose to. they wouldn't need to rely on the onStar system. I can see a nefarious application if they choose to.
Chances are most of these cars have an XM downlink already, this is the more logical choice as satellite radio data can reach places there aren't any FM signals floating around.
All of it is interesting to me as I ponder the nefarious uses of technology and ways I could exploit it. I'm sure there are people alraedy exploiting it. thanks for the chat.
saw this and couldn't help but to think about our recent conversation: https://www.kuow.org/stories/we-didn-t-mean-to-ruin-your-mazda-s-stereo
Stopped reading when I got here:
A few weeks ago cellphone companies switched to a 5G signal. But many cars are still only equipped with 3G and glitch when faced with the newer 5G.
That's not how cellular or radio works.
"Correction: An earlier version of this story incorrectly stated that KUOW switched to a 5G signal. Station operations staff later clarified that 5G is a mobile service standard and bears no relation to broadcast terrestrial service."
