What device to stream music via BT from Pro to radio through 3.5mm jack?

[Shohan]

I have an older radio in my car. It works and I see no reason to buy a new radio with BT just to listen to music. It does have RCA Aux inputs in the back which I have connected to an RCA to 3.5mm stereo jack cable. I used this to play my iPod in the car. What I'm looking for now is basically a bluetooth receiver that I can plug into this cable and pair with my Pro in order to stream the music. I've found plenty of transmitters, like the MSI Bluetooth Music Audio Transmitter FS320, but I'm not sure if this will work in reverse. That may sound like a stupid question, but the only other BT device I have is my earpiece.

So how can I go:

Pro >>BT>> BT Receiver --3.5mm/RCA Cable-- Radio

Why stream it over Bluetooth? I would hardwire it via the audio adapter that comes with the Touch Pro. That's what I do and it's super easy and it wouldn't require any extra money on your part, right?

You will need an a2dp receiver, not a transmitter. Something like this (turned this up in a quick google).

I just wanted to use BT to reduce clutter from having a phone charger and extra cables and stuff. I'll have to try the included adapter. Maybe I'll just have to do that since I really don't feel like spending $50+. Oh well, cool factor out the window.

Try the Jabra BT-3030. I really like mine.
