Eclipse 7100 woes

I just got this head unit and it works fine, but it sure as hell is not intuitive.

I need to figure out how to get more than three letters of each song to show up on usb.

There is a popping noise out of my tweeters on USB.

It defaults to CD when I turn it on

maybe one of you has an IPC module?

I hate how much of a pita this thing is, but it sounds a lot better than my 9887....
