I have the same issue. It's annoying and last for 10 minutes before it shuts off, but if you plug the car to charge it leaves it on indefinately. I am hoping there is a way to turn it off also, but I've found no way.

 

It’s driving me crazy because it means I miss calls and texts if I’m charging my car at home. As much as I love wireless CarPlay, this might make me return the adaptor.

 

It's not what you guys what to hear, but the simple solution is just to added a maual switch, 10-15 minutes and you're done. You could do this at the fuse box (not sure what other devices could be impacted) or at the usb port (two ouside wires are your power wires).

Better yet, connect the power wires of the usb port to another accessory that powers on when the car is on and off when off. As long as you don't touch the middle wires (data) the function of the usb port should be the same

 

There is no fuse dedicated to the front USB port. But the idea of adding a relay in that power wire, controlled by ACC (Fuse F33 for example), might do the trick. If you can get access to the back side of the front USB port, the red wire should be +5v USB power.

Disclaimer - Any info I share regarding the Ioniq 5 wiring comes with absolutely no guaranty of correctness. The documentation consist of hundreds of pages of convoluted diagrams. Misinterpretations are possible, and there may be regional and trim level differences. Touch your car's wiring at your own risk, and proceed with caution. By that I mean it would be a good idea to poke around with a meter to confirm what I have shared. You may also want to access the full service documentation at Hyundai Global Service Way. VPN and a bit of money will be required.

 

I use a USB switch for when I don't want the Android box/CarPlay active.

 

You could probably use an automation app like Tasker on android where you can disconnect when at home based on geolocation or something else.

 

That's a great idea. You could also use the home wifi as a trigger to turn off bluetooth when in range of the WiFi.

 

Mine NEVER turns off, no matter what state the car is in the Carplay is on, permanently - so I can't use any of my Apple devices in my house because it constantly connects to the car. Every day I have to delete the car play connection and then set it up again when I want to drive the car. It's the most insanely crap design I've ever come across and I would strongly recommend that anyone with Apple devices doesn't buy an Ioniq as it will drive you nuts. Thank god I don't park below my office.

 

Just buy a usb lead with a switch…….

 

I know it's an old thread, but I just unplug the USB when I park the car at home. easiest solution and not a pain in the ass at all

 

Old, but interesting. I’ve Carlinkit 3.0 Apple wireless always connected and it definitely shuts down when I lock my car.

 

Someone found a fix using a splitter cable and a power blocker...

Found a trick to get the wireless AA / Carplay adapter...

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...

This hack works very well for me. No need to unplug the dongle when the car is turned off.
Prior to hooking it up, whenever my I5 recharged the 12v battery, the wireless dongle would wake up and grab my phone’s WiFi connection. This would mess with an in progress call, disconnecting if it was over WiFi(?) and hang anything that had an internet connection (e.g. browser sessions.)

(I have very poor cell service at home and WiFi calling is much more reliable and it’s automatically selected by the phone app because of the weak cellular connection.)

 

In case anyone comes here looking for ideas, I just bought one of these and it works perfectly to supply power to the CarPlay dongle from a different USB port that turns off with the car: https://www.amazon.com/dp/B0CZDFGJY5?ref=ppx_yo2ov_dt_b_fed_asin_title

The problem I have is that the CarPlay port stays on whenever the car is charging, which means if it's plugged in in my driveway, the carplay adapter constantly steals my phone's wifi and audio. Super annoying.

I do think it's possible to do better: the stock port doesn't power off for 10min after you turn off the car, so if you leave briefly the dongle doesn't have to reboot. That's quite nice. I do wish there was some device that would power off the port only 10min after the external power got cut. But that's a tall ask and this is a good off-the-shelf solution.

 

I used the cable from Magicable.ca to supply power from the cigarette lighter. Works like a charm.

Here is the video from Niro, but it should be the same for other cars
