2009 Playing Music from Phone

I bought my prius in early 09, and a friend bought the 09 model later in the year.

They're nav screen looks different than mine, but it does one cool thing I wish mine did, which is to play music from my phone via bluetooth. My phone connection works great, but I don't have the same software options in my setup to connect the music via bluetooth.

Is there a software upgrade or something I can do for my version?

Thanks,
Brent
