There is also a similar device that does the same just for Bluetooth - it is basically a Bluetooth Reciver than connects to the RCA sockets in the glovebox. You change to AUX and it plays the music - but all control of album choice is via the Bluetooth phone that is playing the music - something like this:

If you look in this French video - from time index 1:28 this guy is trying to fool everyone into thinking his MyWay can stream Bluetooth Audio - which it can't. What he is not telling anyone is he has a hidden bluetooth transmitter on the RCA plugs that is transmitting the audio only through the AUX source. He is trying to show everyone 'look - no wires or connections' but deliberately fails to talk about the bluetooth transmitter hidden in the glovebox! You can see that he has no control of the tracks from the car - he has to use the phone to do everything and the display on the car is just playing the audio! Hi is trying to con everyone!
Hidden Bluetooth Transmitter - Not Bluetooth Audio Streaming!
To be honest, I didn't mention this as it would likely be 6 points and fine no doubt in the UK if caught fiddling with the phone like that when driving. Just not worth the risk in my opinion.
