Kinda late, I know... I am looking to do the same thing. The cheapest way is to setup an AUX input (you can buy the cable online or make it yourself) and then get a bluetooth adapter that will connect to AUX and accept A2DP music from your phone. I am still searching for a buletooth adapter that also has a mic input, so I can use it both form music and phone calls. There is a Belkin AirCast for example, it's just that the mic is embedded into the unit. Still searching...
