The 2009 doesn't support a music profile (A2DP) for Bluetooth - it was added
In 2010.
The Belkin seems like it would work but you need an adapter to convert to RCA - this music ones includes an RCA adapter but you probably won't be able to switch to phone calls / Siri easily:

Seems like you would need a car power adapter for it though.
