Quick to set up: audio cable into the stereo (RCA), plug the power cord and the receiver indicated by the flashing blue LED, the search for new devices. On my iPhone in the Bluetooth settings of the receiver appeared then as "Amazon_Audio". That's it. Now my old stereo playing music from an attached waistband end iPhone via Bluetooth.

For the price, the only device that uses Bluetooth 4.0, therefore very strong buy recommendation.
