A 10 year old car, if had Navigation, was being fed by a disc somewhere in the vehicle, so the chances of you getting an update could be likely.
10 years ago is 2011. What car in 2011 was still using discs for sat nav?
Maybe 15 years ago, sure. I had a 2004 BMW 330Ci with DVD-based maps which lost support in 2015. Not a bad run.
My 2009 BMW 335i uses its hard disk for nav data. I received an update last year for its mapping data (hopefully will receive an update this year as well). Indeed I still receive live RTTI traffic updates as well. BMW does tend to support its cars a lot longer, and is way more advanced than other manufacturers, though. My 911 doesn’t get map updates any more, and it’s also a 2009.
Conversely, the built-in telematics don’t work, as they’re 2G based. I can’t send directions from my iPhone to my car, for example. Doesn’t work because the supporting infrastructure literally no longer exists.
This works for iOS devices too. Your built-in apps still function fine - Clock, Messages, Mail, even Maps. But stuff which requires a server to relay data
might cease to work as the system’s firmware becomes more obsolete. For example, my iPad 2 running iOS 6 serves Maps data fine, but Safari has issues rendering pages and Netflix hasn’t worked in years. My iPhone 3G running 3.1.3 still loads Google Maps, but Safari is limited to a handful of text-only websites (
m.cnn.com, for example), and Weather / Stocks no longer work.
Maintaining compatibility with obsolete firmware versions is a major attack vector, as later OS releases bring security improvements. For videos, you can still load .mp4 files from iTunes / Finder onto the local device. That works even with an iPod Classic...
I demand Age of Empires II remastered work on that!
