SoundLeaf supports CarPlay, letting you browse your library and control playback directly from your car’s display.

Getting Started

1. Connect your iPhone to your CarPlay-compatible vehicle
2. SoundLeaf will appear on your CarPlay home screen
3. Tap to open and start browsing

No additional setup required - if you’re logged into SoundLeaf on your iPhone, CarPlay uses the same connection.

What You Can Do

Continue Listening

Jump right back into the book you were listening to. Your current book appears at the top for quick access.

Recently Added

See the newest additions to your library. Great for finding that audiobook you just added to your server.

Playback Controls

• Play / Pause
• Skip forward (30 seconds)
• Skip back (15 seconds)
• Scrub through the progress bar

Now Playing

The Now Playing screen shows:

• Cover art
• Book title and author
• Current chapter
• Progress through the book

Tips for Better Experience

Download Books First

Streaming over cellular works, but downloaded books:

• Start instantly (no buffering)
• Don’t use mobile data
• Work in areas with poor signal (tunnels, rural roads)

Download your current listens before a trip for the best experience.

Use Voice Commands

While SoundLeaf doesn’t have direct Siri integration yet, you can use Siri to:

• “Play” / “Pause”
• “Skip” / “Go back”

These system-level commands work with the active audio app.

Current Limitations

No Library Switching

CarPlay shows your currently selected library. To switch libraries, you’ll need to do it from the iPhone app first.

No Search

Browse by sections (Continue Listening, Recently Added) but no search functionality in CarPlay yet.

No Speed Controls

Playback speed adjustments need to be made from the iPhone app. The speed you set there carries over to CarPlay playback.

Troubleshooting

SoundLeaf Not Appearing in CarPlay

1. Check that CarPlay is enabled for SoundLeaf: Settings → General → CarPlay → Your Car → Customize
2. Make sure SoundLeaf is installed (not just in TestFlight on some iOS versions)
3. Disconnect and reconnect your phone

Audio Not Playing

1. Check your car’s audio source is set to CarPlay
2. Verify the book isn’t at the end (100% progress)
3. Try force-quitting SoundLeaf on your iPhone and reopening

Slow to Load

CarPlay fetches cover art and metadata from your server. On slow connections:

• Downloaded books load faster
• Consider downloading your “Continue Listening” books
