I was having quite a few issues with wireless CarPlay. I did some digging on other Hyundai forums (Tucson/Venue) and found that it was quite common unfortunately. Here is a summary of what I gathered:
a) there were less issues with the newer iPhones however I did see many people with iPhone 12s with issues
b) most issues came after a certain time so the group consensus was it was caused by an Apple update.
c) going to the dealership didn’t seem to help, some people on the Venue forum said they had the dealer update the infotainment firmware and it helped however we SHOULD have the most current one
d) some people had CarPlay cut out always the same location so they came so the conclusion it was sensitive to other signals.
e) the new IOS update to 15 didn’t fix anything
I looked up some recommendations and was able to get a solid connection by experimenting with a couple things. I will say I do have a few hiccups here and there. Here is what I recommend:
- Press the reset button on the bottom left. It is a very small button on the panel itself and you need something similar to a fine tip pen. I believe I saw someone disconnected the phone projection (CarPlay), pressed it and waited a hour and connected with no problems after.
I did this, and while there was some improvement, there were still some issues. I read on a forum that the Audio for CarPlay used Bluetooth while the other apps and projection itself used Wifi. Without forum guidance I starting tinkering with settings myself and found great improvement. Keep in mind my words “improvement”.
- Go to settings (not on CarPlay or the phone - the Hyundai screen). Press the wifi option and the only option should be to reset the wifi connection or something along those lines. I found resetting the wifi creates a new link between the phone and vehicle.
- I looked at my wifi connection on my phone and turned off “low data mode” in the phone wifi settings. Not sure if this really does anything for the connection I was having.
After I did this my connection now seems to be much stronger. Can’t guarantee it will work however it helped me not pull my hair out when using my CarPlay.
