Change Google Maps Voice Units & Navigation Settings

This guide shows you how to switch Google Maps between miles and kilometers for voice guidance and on-screen directions, plus how to adjust related navigation settings like voice volume, speed limits, and map display. You can do this entirely from the Google Maps app on your phone or tablet—no special tools or accounts are needed. The steps apply to both Android and iOS versions of the app, though a few menu names vary slightly between them.

What You’ll Need

  • A smartphone or tablet with the Google Maps app installed (Android or iOS).
  • An active internet connection (Wi-Fi or mobile data) to load map data and settings.
  • Your Google account signed in (not strictly required for unit changes, but recommended for syncing settings across devices).

Step-by-Step

Changing Distance Units (Miles vs. Kilometers)

  1. Open the Google Maps app on your device.
  2. Tap your profile picture or initial in the top-right corner of the search bar. This opens the main menu.
  3. In the menu, tap Settings (usually near the bottom of the list).
  4. Scroll down and tap Distance units (on some versions, it may be under “Navigation settings” or “Units”).
  5. Choose Automatic (lets Google decide based on your region), Kilometers, or Miles. Tap your preference—it saves immediately.
  6. Go back to the map. The change applies to all voice prompts, turn-by-turn arrows, and the distance readouts on the screen.

Adjusting Voice Guidance Volume and Language

  1. In the Google Maps app, start a navigation session to any destination (you can cancel after testing).
  2. During navigation, tap the speaker icon in the top-right corner (next to the mute button). A pop-up appears with volume options: Louder, Normal, Softer, or Mute. Select one.
  3. To change the voice language, go back to the main menu (tap your profile picture) → Settings → Navigation settings → Voice language. Pick your preferred language—this also changes the spoken street names and instructions.
  4. If you want to hear voice guidance only when the phone is connected to a car’s Bluetooth, enable Play voice over Bluetooth in the same Navigation settings menu.

Managing Speed Limits and Speedometer

  1. Go to Settings → Navigation settings.
  2. Toggle Speedometer on or off. When on, a small speed indicator appears in the bottom-left corner of the navigation screen.
  3. To see speed limits on the map, toggle Speed limits on. This shows a small sign with the current speed limit on the road you’re driving on.
  4. Note: Speed limit data may not be available in all regions. The speedometer uses your GPS, so it may not be accurate in tunnels or areas with poor satellite reception.

Changing Map Display (Dark Mode, Zoom, and Details)

  1. Open the main menu (profile icon) → Settings → Navigation settings.
  2. Under Map display, you can toggle Automatic zoom (which adjusts the map scale as you approach turns) and Show traffic (overlays real-time traffic conditions).
  3. To enable dark mode, go to Settings → Theme and choose Dark, Light, or System default. Dark mode reduces glare at night.
  4. Back in the map view, you can pinch to zoom manually. The zoom level resets on each new route unless you enable automatic zoom.

Setting Up Voice Commands and Alerts

  1. In Navigation settings, find Voice commands (or “Hands-free”). Toggle on Voice commands to use “Hey Google, navigate to…” while driving.
  2. Toggle Traffic alerts to hear notifications about accidents, slowdowns, or construction along your route.
  3. For lane guidance, make sure Lane guidance is on. This shows which lane to be in for upcoming turns.

Resetting to Default Settings

  1. If you want to revert all navigation settings to their original values, go to Settings → Navigation settings.
  2. Tap the three-dot menu (or “More”) in the top-right corner of the screen.
  3. Select Reset and confirm. This restores all toggles to their default state, but does not delete your saved places or history.

Common Mistakes

  • Changing units in the wrong app: Some users mistakenly change units in the Google search app or another navigation app. Make sure you’re in Google Maps.
  • Expecting voice units to change immediately during an active navigation: The unit change applies to the next route you start, not the current one. You may need to stop and restart navigation.
  • Assuming “Automatic” uses your phone’s language: Automatic units are based on the country your device is set to, not the language. A phone set to US English will use miles even if the app language is French.
  • Toggling speedometer but not seeing it: The speedometer only appears during active navigation, not on the regular map view. Also, it may not show in some countries due to local laws.
  • Muting voice but still expecting alerts: If you mute voice guidance, you also mute traffic alerts and other spoken notifications. Use the “Softer” option instead if you want quiet but audible alerts.

Tips

  • If you travel between countries that use different units, set units to Automatic—Google Maps will switch to miles in the US and kilometers in Europe, for example, without manual changes.
  • Use the Softer voice volume for a less intrusive experience—it’s often loud enough to hear over music but not distracting.
  • For long trips, enable Automatic zoom to keep the map at a useful scale without fiddling with pinch gestures.
  • Check your speedometer against your car’s speedometer occasionally—if they differ, your GPS may be inaccurate or your car’s speedometer may be off.
  • On Android, you can quickly toggle voice guidance mute from the notification shade during navigation—no need to open the app.

Troubleshooting

  • Unit change doesn’t stick: Force-close the app (swipe it away from recent apps) and reopen. If it still reverts, restart your phone. Also, check that your device’s region settings (Settings → General → Language & Region on iOS, or Settings → System → Language & Region on Android) are set correctly.
  • Voice guidance is too quiet or silent: Check that your phone’s media volume is turned up (not just the ringer volume). On Android, press the volume button while navigating and adjust the media slider. On iOS, use the volume buttons on the side. Also, make sure the speaker icon in the app isn’t set to Mute.
  • Speedometer not showing: Ensure you’re in navigation mode (not just browsing the map). Also, verify that the speedometer toggle is on in Navigation settings. If it’s still missing, your region may not support it—try changing your device’s region to the US temporarily as a test.
  • Settings menu is missing options: Some older versions of Google Maps may not have all the options described. Update the app to the latest version from the App Store or Google Play Store.
  • Voice commands don’t work: On Android, ensure Google Assistant is enabled. On iOS, you may need to enable “Hey Siri” or use the in-app microphone button. Also, check that the app has permission to use the microphone (Settings → App permissions).
  • Units change but voice still says “feet” or “meters”: This can happen if the app is using a cached voice pack. Clear the app cache (Android: Settings → Apps → Google Maps → Storage → Clear Cache; iOS: offload and reinstall the app).

Frequently Asked Questions

Does changing units affect voice guidance or just the on-screen display?

It affects both. The voice prompts (e.g., “In 500 feet, turn left” vs. “In 150 meters, turn left”) and the on-screen distance readouts will use the unit you select.

Can I set different units for walking and driving?

No. The unit setting is global for all modes—driving, walking, cycling, and public transit. You cannot have miles for driving and kilometers for walking simultaneously.

Why does Google Maps use miles when I selected kilometers?

This usually happens if your device’s region is set to a country that uses miles (like the US). The app may override your manual selection if “Automatic” is chosen. Try selecting “Kilometers” explicitly, and ensure your device region is not overriding it.

How do I change the voice language without changing the app language?

Go to Settings → Navigation settings → Voice language. You can pick a different language for voice guidance while keeping the app interface in your preferred language.

Is the speedometer accurate enough to rely on?

The speedometer uses GPS data and is generally accurate to within a few mph/km/h, but it can lag or be inaccurate in tunnels, heavy rain, or areas with poor satellite visibility. It’s best used as a reference, not a substitute for your car’s speedometer.

Can I change the units from the navigation screen without going into settings?

No, there’s no quick toggle on the navigation screen. You must go through the Settings menu. However, you can quickly mute voice from the speaker icon during navigation.
