FLAC playback in car?

[Guest TooBigToFit]

I'm getting my license next week, along with my car (a hand-me-down 1999 Subaru Legacy, should serve me well). A large majority of my music is in FLAC, and resides on my Omnia (I plan on getting Kinoma Play real soon, awesome app), and also my COWON Q5W. Anyways, I was wondering if there was a way I could use Bluetooth to play the FLAC files on my Omnia through the car speakers. Most bluetooth car receivers make themselves seem as if they were solely for making calls. Worst case scenario, I'd probably use a line-in. Never liked those FM modulator things or those casette devices. Any recommendations, whether a specific route to take or a specific device would be great. Thanks!
