Phone: person I call cannot hear me

[Debbie]

I am having problems with my phone. Connectivity is not a problem, when I make a call the person cannot hear me but I hear them just fine. I took it to Menlo Park service, thought they fixed it but it only worked for one call. I waited for 4.2 but that did not help. Any help would be appreciated. I am using iPhone 3GS.

If you have the 4.1 software or later, try using the voice commands for Slacker or navigation. I suspect the same microphone is used for these and the hands free phone mode. If the voice commands don't work then there might be a problem with the microphone or its wiring. This could help Tesla service pinpoint the problem. If the voice commands work, then maybe the Bluetooth module had a bad audio circuit or there is a separate microphone and circuit for voice commands.

I have similar issues intermittently. My microphone seems to work fine otherwise.

I've only had the same problem once. On another thread I read that pressing the left thumbwheel will mute (or unmute) an active phone call. I've only ever used it to mute music playback, so I wonder if I didn't press it out of habit when receiving a call and accidentally mute the call? I'll have to try it deliberately now and see how that state is displayed so I know what to look for.

If it's a guy on the other end, Debbie, he can hear you just fine.

This is most likely an issue with your phone, and not the car. My wife's iPhone began exhibiting the same behavior, regardless of whether she was bluetoothing in her car or mine. Happily, it was under warranty, and Verizon promptly sent us a replacement.

And sometimes it's the cellular connection itself. Two channels are required (so we can talk and hear at the same time) and sometimes one channel doesn't connect.

Try to test in another car with Bluetooth to narrow it down to the car vs. the phone.

With old LS 460, there was a hidden diagnostics screen that I used to adjust the microphone volume settings. Doing that improved the quality of my voice on the calls.

Tesla could add this as an option for the phone settings screen for each phone - like the microphone settings in Windows, where you could do a test - get a volume level bar to see what the car is hearing - and then adjust the volume accordingly.

I had several cell phones while I had my LS - and had to adjust the settings for each one to improve voice quality.
