I installed it in the head unit KIA RIO 3. I used the USB port of the radio (Ipod) for power supply. Works well, without delays and interference. Connects automatically within approx. 2-5 sec. The sound quality of course suffers slightly on 3+. Hearing does not cut, but the difference with listening to AUX is noticeable. Most likely this is due to the fact that this adapter supports only the most primitive audio codec for Bluetooth - SBC, which is a significant minus among compeors.
