AFAIK only the Dension GW-Pro & GW300 (may be newer versions now) displays track information in the DIS and have USB as well as track information, I Have the GWPro fitted, it gives USB/Ipod/BT Streaming and BT phone kit. But really it requires a MFSW to control it. You can do it from the head unit but not fully and it's tricky. I also use it for my DAB interface and that works well, very little dropout with a decent antenna. I was using the DAB/AMI setup, but this was causing me too many issues.
