good idea, but unfortunatly not usable for me ;-)
I have a MPAV 9000 and it is hocked up to my Avant. it works well to play CD or Radio (controlled through Beo4/BL1000)...but the main problem is that the buttons on the MPAV does not work... so I was thinking about conneting the buttons on the MPAV to a old BL 1000 circuit board to send the IR commands to the AVANT...and then it should work!
it might not be the best solution but it should work...and be a little fun at the same time.
I was hoping that the buttons on the BL1000 would have been more of "real" buttons so that I could soild cables from them... but that was not the case.
