It's possible someone will want to do this, but there are a few things working against you. The main problem is that the Empeg, for most people, replaces the need for a CD changer. Some people still like to have some CD's on hand, and not everyone who has a CD changer immediately sells it when they get an Empeg. But the problem is that although someone's got the specs for Blaupunkt's interface, there are dozens of other interfaces to CD changers out there. Since there's no standard, and the Empeg is such a small market product, there isn't a very wide audience for any particular type of CD changer. If there was a universal spec, there might be more motivation for someone to write it. But I would say a majority of the people who buy an Empeg end up selling their CD changer... What's the point in having it when you have all your music instantly at your fingertips?
