I have an expensive kenwood touchscreen radio that I bought right before the lightning port was introduced, and support for lightning was never added as a firmware update for the radio. The radio also doesn't have bluetooth support (which at the time didn't matter to me because I could just plug my phone in with USB and be good to go). I use the aux jack in my car every single day to listen to music when I'm driving. Is it time for me to update my radio? Maybe. Should I avoid kenwood in the future for not supporting an expensive radio? Hell yes. Am I just irritated in general about this entire situation? Of course. The continued money to support things sucks. My PA/sound systems also will require adaptors to play music here at home if/when I choose to upgrade my iPhone.How many people even have a radio that has an aux jack? How many people use it? How many people don't have usb port in their car or bluetooth audio?
Edit: also, I'm sure someone will come out with cable with headphone jack and charging port. But I still argue that this is a super small group of people.
