Corolla S 2014 - hands free calls are hard to hear, but other Audio (music, etc) work fine

#1
Hi, recently in my Corolla S 2014, my hands free incoming phone calls seem to be very low. Instead of the sound coming in on the door speakers, it appears to be coming out of the center of my console and is very hard to hear. People can hear my outgoing calls.
When I play music or play audiobooks from Audible/Overdrive apps on the phone, the sound is perfectly fine.
I have removed the phone's Bluetooth profile from the car, and removed the car's Bluetooth profile from the phone and paired them again. But it doesn't seem to help.
My phone is a BlackBerry Leap (OS 10.3.3.1463) but I tried my husband's iPhone as well. Same result.
The dealership says I have to buy a new speaker system ($400) to fix the issue. I hope there is another fix, like a firmware upgrade, that will remedy this. Any suggestions appreciated. Thanks!

Have you check if the "in-call" volume is at an appropriate level ? (Setup/Phone menu on the touchscreen) ?
I doubt the speakers are in cause, since you say they work fine otherwise.
I also doubt the sound come from the center of the console, since there are no speakers there... Unless it's from the phone itself ?
Maybe there are some settings to check on the phone ?

Any update on your issue? I use 2014 Corolla S plus. From last few weeks i'm facing similar issue on my car. Has problem only with phone calls, rest of the music/radio/youtube video sound plays well. Hope your reply may help. Please let me know. Thanks in advance.

Make sure your phone volume is set adequately since it may be set too low and even though car volume is set high it'll still be to low. You would think that it should reflect phone's settings but I've had weird situations similar to what you're describing by adjusting phone's conversation volume.

I checked all volume settings in phone and car, but nothing worked. In addition, i also verified with friends iPhones and Android phones, the result is the same. Music/maps apps like Spotify/Waze/Google Maps/All other apps work with perfect sound quality over bluetooth. Only issue with phone calls, low volume/cracking sound/only 1 side front speaker works with low sound. People on the other side of the call can hear my voice without any issues.

Not sure how to fix it.

2014 Corolla S plus, Bluetooth version is BU.70.27.

Went to the dealer today, he is asking to pay for the upgrade for BU.70.31. But not giving any guarantees that the upgrade will fix the issue. This makes me to rethink about upgrade the version to BU.70.31.

You probably know this already but the phone volume has to be set while you are talking on the phone to some one. It is completely separate from the music volume.

I checked it too, no difference. The call volume, phone volume and ringer volume all are full. Still the speaker are not working for only phone calls. Planning to visit the dealer again. Will see if they can fix it without changing the entire set.

Same problem here. I’m on BU.70.27 and was on 20.x ish when I got the vehicle but worked fine on BU 70 for months. I did notice a couple times before this issue happened that my phone call got merged with my Bluetooth music, so I could hear both coming from the Center dash or whatever. I have a feeling calls come from a separate speaker and that speaker is blown. I’m speaking with my dealership about it.

Having exactly the same issue here. Tried several other phones, they all work fine in other vehicles for both calls and regular bluetooth, but calls in my 2016 Corolla S are very low as described by others, and seem to only be coming from either the dashboard or the driver's side door speaker. Can barely hear even at max volume. The people I call can hear me fine.

No the one in the front doors, the conectors where totaly disolved by corosion of some kind, and the phone system is using only those two.
