Ogg vorbis playing head unit?

[Refefer]

Hey, I'm looking for an OGG file playing head unit to upgrade the stock cd player my car has (1999 Mustang V6). Most people would say just convert my files over to MP3, but the problem is that I have encoded nearly 16000 now in that format and am very conscience of audio distortion (which is why I originally coded them all in OGG because of it especially good quality) which I would certainly get if I were to convert from one lossy format to another.

I've been looking around on the net and have found only hack job ways of doin it using an external players and I really want to avoid that if possible.

Any ideas?
