Telephone Buttons Not Working

[CJFleischmann]

I picked up my new 2006 X5 a month ago, and bought a bluetooth phone (not 100% compatible, but still able to pair the device). All of a sudden on day none of the telephone buttons work (bot steering wheel and dash). I took it to the dealer, and they could find no "codes" or otherwise figure out the problem. They said there may be a new "software download" but I have heard nothing further from them. Has anyone esle experienced this problem? Does what they are telling me make sense? Although I never had bluetooth before, I feel like now I am lost without it. Please advise.
