Not sure how you're set for cash but the best method I found is to head up to Amazon and pick up a nice stereo like the Kenwood KDC-BT555U. Not only does this have blue tooth, AUX and a USB port, that I use to death, but her 920 would upload all the phone numbers from her phone to the Kenwood until needed. Then, while she's out bumpin' Tupac or Enya's Sail Away and the phone rings, boom, the Kenwood mutes the music and switches instantly to hands free. No ear piece needed. My wife loves that feature. Same goes for text messages. You get the voice of Cortana reading her messages out and doing replies too. All she has to do is steer the car. All for about 225.00, less if you know how to do installations.
