I want to know does this device support USB flash drive/hard drives in addition to the ipod? If so, does the device itself take care of decoding or is it left up to the BMW head unit? If it's the device, what formats/codecs are supported? (Especially any lossless codecs. The BMW professional head unit supports WMA lossless).
Just retrofit the Combox.
