Shark Attack

I have the 6 disk unit connected to the stock head unit.

So tonight I took out the becker and installed my Blau mp75 seattle.
it plugged right in I was shocked.... the 6 disk will not work. Everything else works fine. Anyone else do this swap and know a trick to make the 6 disk work..

The changer doesnt even have power with the blau installed.

Any good audio philes here that have been where I am?

No specific experience with the changer, but with my Blau headunit there's an option for turning on auxillary devices in the menu. Did you set that to "on"?
