Found this trick from a sportage owner. If you have a wireless AA or Carplay adapter that doesn't turn it self off like mine you either need to unplug it or put a switch on it so it won't keep connecting and disconnecting for hours in your house. But if you buy a USB Y cable and a USB power blocker you can make it automatically power off and on with the car. Put the Power Blocker on the Ioniq's USB port, it will pass though data but not power. Then plug the other side into the lighter socket, it only powers on when the car is on. So the adapter only now gets power from the switched lighter socket and not the USB port, so it turns on/off with the car. I tried it tonight and it worked great, powers on with the car and connects to wireless AA then turns back off with the car.




The right angle adapters are optional, I did it to keep the cable out of the way. Or you could also pull apart a USB Y cable and cut the power wire
, leave the data wires.
