Looking for the best way to do this. I know I can replace the entire head unit with something modern (I'd love suggestions on that). But that's expensinve.

The adapter methods I've seen involve taking over the CD changer port (Enfig, Crux, Yomikoo) I've not found one where I can do audio -and- charging using a single USB cable. Is there such a beast?

What do y'all recommend?
