> the cellular contract GM had for vehicle connectivity expired
reply2022, I got a letter saying that my car's crash response SOS system will stop working because FCC is retiring the 3G spectrum it is using.
The car clock however is synced to the GPS instead.
If GM used NTP instead of GPS, then it makes sense that it stopped working arbitrarily around 2022.
Older versions of the GM OnStar hardware used 2G cellular radios and carriers have decommissioned those networks. Adapters are available for some vehicles to use newer networks.
replyConsidering that OnStar spies on you even if you don't subscribe to the service it's much better to just leave it broken, or even to actively disconnect it in newer vesicles.
replyIn 2019 there was a GPS week number rollover, another possible cause.
replyIt seems absurd to me that cars needs a cellular connection to automatically set time, meanwhile 10$ clocks can get the time correctly from the radio signal that are broadcasted. More insulting the fact that the car itself has an FM and also an AM tuner that are capable of receiving time signal and decoding them while the radio is not in use. And that modern cars that use digital radio (DAB) have a standard to get the time. Come on, car infotainment is so outdated...
