DSC and button issues...

[hotimportknight]

Can't really think of a better title for the thread, cause its a wierd problem I havent been able to figure out for quite some time now. Right after I installed my Alpine IVA-D310 touchscreen DVD head unit, my buttons that turn on/off the DSC (right below the little flippy door storage comartment thing) and the button that has the green LED in it with the speaker, that i have NO idea what it does... But it made the stereo sound better when the green LED was on... stopped working, wont do anything, DSC is stuck ON. and the speaker button is stuck off. Does something for this assembly run through the stock CD players wiring harness or some thing? I didnt have any left over wires that I can remmeber. Oh yeah, my car is a 2000 323ci coupe 5 speed. I havent been able to find any help on other forums, i never even got a response on bimmerforums maybe I'll have some luck here, if some one knows please help me out! Thanks!

ps. if any one else knows what it could possibly be caused by give me some ideas too... thanks!
