How DICE handle unicode charachters in ID3 tags?

I have cyrillic charachters in many songs, wonder how it's going to look.

I would like to mount iPod in CD changer area (2003 x5 with business CD. No DSP) and operate it through steering wheel only. Is all cables included to do that? I don't have CD Changer.

what is the latest DICE firmware version? How much does it cost to upgrade older unit?
