🐜 Apple CarPlay Bug 📞




It doesn't matter if I initiated the call or if it was an incoming call, the remote person can barely hear me.
In the rare event that everything does work, it will only work once. Any subsequent phone conversations revert back to the original issue.
Also, disconnecting the cable (which disables CarPlay) temporarily resolves the issue, but that defeats the whole purpose of CarPlay.
My iPhone 11 Pro Max is up-to-date with the latest iOS (v13.3).
As per other internet website suggestions, I have tried all of the following—but none have worked:
- Toggle the “Audio” icon when the phone is in the process of calling. (this did not fix the issue)
- Tried different cables, including the Apple OEM cable. (this did not fix the issue)
- Turned Bluetooth off—although Lexus Enform will disconnect BT when CarPlay is connected via cable. (this did not fix the issue)
Who else is experiencing this?

My LS and the lady's IS, have had zero issues, but then again, there was no Apple Carplay in either. I've yet to see if I connect via just Bluetooth if the sound quality will be any better or any worse compared to connected to Apple Carplay.

The issue is with the microphone when connected to Apple CarPlay via the USB cable. Using a cable is the only way to connect to CarPlay in the UX—at least for now. By design, BT is disconnected when CarPlay connects (Enform disconnects it).

Edit: apparently this is a common issue amount CarPlay users:

I saw a possible work around from a Rav 4 forum. Apparent for some people if you switch to speaker and then back to normal on the phone during the call the audio issue is resolved, at least for that call. You have to do this for every call though.
I haven’t had a chance to test it yet but I will report back if it works.

Yesterday I plugged in the phone midway through my drive and audio quality was bad.

However, many times the phone conversation works flawlessly the first time but—on subsequent conversations—the microphone stops working (thus, the remote person can barely here you).
Were you able to test this in that fashion?

This was fixed in Beta 2 back on 14-Jan.
Anyway, I'm finally happy with my Lexus UX and CarPlay integration!
