I use this equipment for BMW E46 Business CD. The sound quality is good, the playback starts quickly. But: The equipment displays the titles on radio screen only if the ID3 tags are V2.3 ANSI coded. The V1 tags are not diplayed (shown 'No title'), and if V2.3 tags are coded UNICODE, then two asterix (**) and the first character of the title is only Displayed. With BMW Business CD radio supports only 9 folders on USB, and only the first 6 Folders Can Be Accessed Directly (with buttons 1-6), rest can be played by pressing 'next' several times ... And the playback order inside of a folder is chaotic: it plays in the order how what files copied on the USB (not alphabetically ...)
