Im getting tomorrow my G30 with Harmann Kardon system and got really serious about using its maximum potential.
So main questions are:
1) what audio formats are better to use (mp3, AAC, flac etc.). Heard that flac has noticeable difference and is much better.
2) what is the best way to play files not loosing their quality (connect USB storage to car or use Apple CarPlay or connect phone via USB or just save music on cars harddrive).
