I picked up a Viseeo (or Bovee?) Tune2Air and I'm really impressed with the sound quality streaming music w/ iPhone/iPod and Pandora.
I got the WMA2000 which is the USB only version. Plugged it in, connected up on my iPhone & can stream music or Pandora to the head unit and still control the music from the steering wheel. Volume & tracks skip + track name shows up on my stereo. The sound quality is really good too. Just like plugging in w/ the apple USB-to-lightning plug.
I got it from here:

I'm not affiliated with them but just a happy customer
The wma2000 worked for me b/c I have the combox 6VC and 6FL usb/audio interface . Calls still work via my Bluetooth. It muets the music when I get a call and when the call is done plays on.
