QuietFSD opens a silent, call-style audio channel to your car over Bluetooth, so the car treats your phone as being on a call while you drive. Your music keeps playing, and nothing is ever recorded.
Getting started
- Open QuietFSD and tap Start once. The first time, iOS asks for microphone access — grant it. (It is needed only to open the call-style channel; the microphone is never recorded.)
- Connect your iPhone to your car over Bluetooth.
- Tap Start when you get in, and Stop when you’re done. The status screen shows whether the channel is active, how long it has been running, and which audio output is in use.
Hands-free ways to start
- Siri: “Hey Siri, Start QuietFSD.” You can also say “Stop QuietFSD.”
- Action button: Settings → Action Button → Shortcut, and choose the QuietFSD Start (or Toggle) shortcut.
- Automation: In the Shortcuts app, create a personal automation — “When my iPhone connects to [your car]” → run Start QuietFSD → turn off “Ask Before Running.”
Good to know
Does it record me?
No. The microphone input is never read. The audio session only renders silence to keep the call-style channel open.
Why is the orange microphone dot showing?
iOS shows that indicator whenever an app has an active call-style audio session. It reflects the session type, not recording — QuietFSD never reads the microphone.
The app shows a “not routed to Bluetooth” warning.
That means audio isn’t currently going to your car. Make sure the iPhone is connected to the car over Bluetooth and that the car is the active audio output, then start again.
It says “interrupted.”
A real phone call (or Siri) interrupts the channel. After the call, start QuietFSD again — by tapping Start or with Siri.
My music paused.
Music coming from the car’s own source keeps playing. Music played from the iPhone may pause while the channel is active, because the channel behaves like a real call.
An automation didn’t start it.
On a locked iPhone, iOS may show “unlock to continue” instead of starting automatically. Glance to unlock as you get in, or keep the phone mounted.
