2023 Tacoma Buzzing Sound on Phone Calls

Just picked up my 2023 Tacoma V6 Dbl Cab 4x4 about 2 weeks ago. So far, I love it and glad to be back into a Toyota (last Toyota was a 1998 4Runner I loved). I didn't notice it at first and don't think it was doing it, but I noticed this week, when I or my wife are connected either bluetooth or Carplay, the person on the other end hears a "buzzing" almost like old car door open alarms. This is with either of our phones, both iPhone 13 Pros and either plugged in or not. The only thing I have done is set up our camera for our rear-facing toddler, but I have tried it both with it plugged in or unplugged and same issue. I saw some posts regarding it on here and Reddit, but no solutions. Any recommendations? I haven't tried looking for any head-unit updates, but will later today.

 

Wild guess. Perhaps you have a bad ground on the microphone in the head unit.

 

Could be. Like I said, I didn't notice anything the first week. Could have bounced something loose but just been normal driving so far.

I looked on the Toyota website for a head unit update and there was one. I updated through the USB port, just haven’t verified if it was fixed yet. One of the release notes was calls through Apple CarPlay and android auto so maybe!

 

Welcome to the club!? Unfortunately not a new thing, and you will find a few threads if you search around. So far I have not seen anyone find a fix.

Update with a fix!

I lowered the volume and it helped but it didn’t completely silence the humming. Can’t believe Toyota accepts this in their trucks.

 

Post in thread 'Apple CarPlay/Bluetooth Issue???' This fixed it for me!
