Am starting to look into HeadUnits that can read USB Thumbdrive or other sources like SD cards etc. 1 of them is enough. But I have the following criteria:
1.Capable of reading big drives i.e 8GB & above
2.Capable of reading all common music files regardess of how many folders, how long & language of the filenames, mp3 kbit/vbr
3.Quick reading, not much waiting/buffer/searching time
4.Good sound quality & settings available
5.Can output Chinese/Japanese or even Korea Filenames of music files.
