Just bought a new car (2017), plugged in my 80 GB gen4 iPod classic via USB port but the car never recognizes it (but it charges it!). My wife's car (2013) does the same thing. The car I just sold (2009) always worked great but now I find myself with a hard drive of all my tunes that will not work. I've found male 30-pin to female Lightning adapters but their descriptions state they don't support data, only charging. Apple no longer supports that iPod. Is there any way to fix this?
