2019 Trail Boss Phone/microphone issues

[Gcrew]

It’s been 3 month since I took delivery of my new 2019 Chevy Trail Boss and really hate that when I use the phone to call out the person on the other end can’t hear me.  This is the same whether the Apple iPhone is connected to car play or via Bluetooth. Also same problem when I initially called on star to set up service. They couldn’t hear me. First thought it was cell phone reception but was not the case. First time the dealer replaced the mic over the  drivers side but this didn’t fix the problem. Updated latest software updates and this too didn’t fix the problem. Took it back to Chevy dealer Monday they called today and said they can’t replicat the problem. So drove up from work in the loaner and replicated the problem. 

 

Same problem on iPhone or Android. 

 

Has as anyone else had this issue or has any tips to resolving the issue?

 

thanks

I have a 2019 Silverado LTZ and I've experienced the same situation with the phone where the person on the other end can't hear me. I brought it to the dealer and they determined it was the microphone and replaced it......they said it was fixed but it's not and still has the same issue.

Has anyone found a fix to this issue?

This is currently happening to me, no resolution so far unfortunately.

I had someone call me and I couldn't hear them.

They could hear me, but there was no incoming call sound.

Turns out I needed to turn up the radio volume when it was first used. Then I could hear them.

Apparently when the phone connects a call the phone volume is independent of the music volume. 

Now it works as it should.

I just bought a used 2019 Silverado Custom and am having the same issues. When I make a call I can hear them and they can't hear me. If I use the mic button on android auto it's not picking up any sound either. Have you figured out how to fix this?

Check the fuse for Onstar.  I did this to myself accidentally on my 2019 LT trying to disconnect Onstar.  After I pulled the fuse, the microphone didn't work for calls but I could hear the other person.  When I put the fuse back in, it started working again.

 

I pulled the F42 fuse in the passenger side (right) fuse panel.  It is listed as TCP which is for Telematics Connectivity Platform.  

 

Hope this helps.
