Ok, so first off, HI! I just bought an '03 3.0 X5 about three weeks ago. I have to say. . . Its like I just won the popularity contest at work and with my friends/neighboors. What a feel good car! Then I found this site, talk about a wealth of information. I have already installed the aluminum guage rings and have some more stuff on its way.
Now to the meat, there are some options that are not on my X5 that I have read about/seen on this site that I would love to have. That damn phone button on my BC screams at me everytime I look at it "PUSH ME! PUSH ME! HAHAHA I DO NOTHING FOOL!!" What would it require to make that button work and/or can I make it bluetooth and have the speakers/built in mic work with it?

Any info is great info, thanks in advance!
