CarPlay arbitrarily mutes microphone during call.

New software upgrade is available that addresses this issue. I can confirm this.

Had it done last week. Owner of a 2024 WRX.

Check the link below - make an appointment at your local dealership to get the upgrade for free.

Applicable cars:

• 23-25MY Outback/Legacy Models (including Wilderness models)
• 23-24MY Ascent Models
• 24MY Impreza
• 24MY Crosstrek (including Wilderness models)
• 24MY WRX
• 25MY Forester

New software version numbers:

• FM1WMM073-980 (Mid model software)
• FM1WBM073-980 (Base model software)

ISSUE RESOLVED!

• Wireless connection drops while using wireless CarPlay due to external signal interference from surrounding facilities etc. (only applicable to HIGH and MID trim)
• During CarPlay handsfree call receiving party is not able to hear the caller as the microphone data is muted

I received the following email from my car Subaru car dealer:

Subaru has released an update to correct your Subaru’s microphone from being muted while using Apple Carplay. If you have experienced the other party not being able to hear you while on a phone call using your Apple phone, this update will likely fix this issue from happening again.

This audio update will be performed at no charge to you.

Go to the dealership and request the upgraded software. This fixed my 2024 WRX CarPlay Issues completely.

It’s not an Apple issue. It was a software issue on the Subarus. Just had my software updated today and it got rid of this annoying issue. The update has to be done at the dealership so make an appointment.

I have this same issue. From what I have found out, there is no real “fix” for it yet. To get “around” it, you can switch to speaker on your phone, then go back to CarPlay and they can hear you. I have yet to have the other party say they cannot hear me AFTER switching back to CarPlay from selecting speaker the first time the mic drops. I have made some noise about this to Apple support, SOA/dealership, and on Reddit. Kind of a safety issue in a sense too.

Also, deleting car from CarPlay and from Bluetooth on phone, then Hard resetting of phone, followed by factory reset of head unit, turning car off, opening door to kill electronics, then starting the process over from scratch…DOES NOT FIX THE ISSUE.

they fixed this - it's a problem with the radio. go to the dealership and request the update for the radio.

I have the change log and link in this thread somewhere. It fixed my issue.

Same issue here. 2024 outback wilderness. Have tried restoring my phone and set up as new even the issue still persists. There are several other forums out there of hundreds of people having the same problem. It is not limited to iPhone Subaru acknowledges the problem, but does not provide a fix.

The only workaround is as someone above side, go to your call screen on your phone, switch to speaker or phone and then switch back to CarPlay.

I would encourage everyone here to please reach out to a Subaru. Customer advocate and share your complaints. They have offered to credit me $1000 service or parts credit.

Sucks because it still does not fix the issue.

Same thing happens with our new 2024 Subaru Outback. My voice drops out on their end after a minute or two. I can always hear them over the car’s infotainment speakers. If I grab my iPhone 13 and switch to hearing it on the iPhone speaker or connect the call to my Bluetooth hearing aids, they can hear me if they haven’t already hung up by then. If I switch back to CarPlay in the Subaru, they can hear me again. For a while. But it happens often. And is annoying.

YES!

Go to the dealership and request the new firmware!

This is also happening with my 2024 Subaru Outback Touring XT. So frustrating!!!! I have iPhone 13Pro and I have to switch call to “speaker” then back to CarPlay for it to work again. Total safety hazard if I’m the driver and not a passenger.

I’m having the same issue with my brand new 2024 outback. Nothing seems to fix it, but switching to phone audio and back like others have mentioned.

2024 Outback Limited XT, and the exact same issue. Nothing fixes it so far but I have found that if turn to speaker phone they can hear me again. Really annoying that this is happening and neither Subaru or Apple seem to care.
