bluetooth not working.

[Bdh821]

I can't say it doesn't entirly not work, but it doesn't show my contacts, display anything on my stereo screen when calling or being called, and my botton on my steering wheel doesnt work anymore. I tried resyncing everything and it still doesn't entirly work. What does work is actually talking thru the stereo still but I have to physically open the phone to answer or find a contact.... WTF?! This is more of a rant then question of how to fix it. I assume I'm going to have to bring it in for service which is a wicked PITA
