I checked into this a while back. Too much hassle, and it not exactly cheap either. I also checked into it again when I swapped out my stock radio for an Alpine unit that was "Bluetooth ready". I can buy a Bluetooth model that is supposedly plug and play, but now my radio is considered "old because it was made in 2008, so I will have to but adapter cables as well. It will cost me damn near $350 to add Bluetooth to my "old" Alpine radio. For that much, I will just upgrade to a newer radio when I get around to it, and with more features than just Bluetooth. Pandora app compatibility is a good feature to have, we have it in my wife car and it's the shiznit.
