on normal pioneer units the full speed ipod converts media to the wav PCM format and sends the datastream to the unit.
the unit sees it as reading a normal audio cd so theres no loss.
on this i dont understand why they made an analog audio connection instead.
when theres usb present.
you can try loading it
but from what i understand itsa hardware decoder that they use so even tho theres windows theres no hardware chip to decode FLAC.
i ve been beating that dead horse on pioneer dealer forum and all i get from pioneer.
well we working on it
well i dont know
umm yea maybe sometime in the future
and all kinds of other excuses...
but maybe someone is smart enough to integrate a software decoded into the system
