I currently use a product put out by parrot.com. The item is MKI9200. This product allows you to stream music from apps such as last.fm or IHeart Radio, Stitcher etc. I've used this product will a Blackberry 9000--->9800--->Samsung Galaxy Note. The MKI9200 will import your phone book contacts into the setting so that when you receive a phone from someone in your contacts it will announce over the car stereo who's calling. When your phone call is ended your music or podcast will resume. I've had this product for 2yrs. now. This item was permanently installed in a 00' Ford Explorer.
I had the Parrot installed by my radio shop here in Texas. Visit YouTube and search for parrot, so you see how the item works. My Eclipse CD5030 has BT capabilities just for the phone. The only downside going this route is that the BT will sometimes drop off. I use the parrot on my daily commute to and from work. Hope this helps.
