The problem, according to Mazda, was that the radio station sent out image files in its HD radio stream that did not have extensions
Why on earth is your radio station sending out image files, with or without extensions, in the first place? Isn't radio supposed to just be audio? Or is this some new thing where it sends out images to be displayed on the console that are relevant to the story on hand? And even if that's the case, what's the point in sending someone's car those pictures when the car driver is supposed to be driving, not looking at whatever picture is coming up on the console?
