Nope, still Apple. There's no good reason that the iPod couldn't use a standard protocol. For that matter, there's not much reason not to just read it as a USB drive and let the car's internal music player do all the work, even if just as a fallback.

I can kind of understand why Apple would want the entire world to only work with their proprietary connector, but for the life of me I still can't figure out why anyone else, especially auto manufacturers, went along with it. It's a horribly short-sighted decision for products like cars which regularly have a useful lifetime measured in decades.
