Okay, I got A2DP to work in my Acura TSX. I didn't do anything different from last week. All you have to do is pair your phone with the HandsFreeLink and it should connect with Bluetooth Audio. I'm still not sure why it didn't work last week, but whatever.
If you're having problems, I found this page from another forum that might be helpful:
