Google Maps Voice Navigation Not Working on LG G5? Fix

If Google Maps voice navigation is silent on your LG G5, the problem is almost always a settings conflict—either the app’s voice is muted, the phone’s media volume is too low, or the app lacks the permissions it needs. You can usually restore spoken turn-by-turn directions in under five minutes by checking a few specific settings, and this guide walks through each fix in order.

Why Voice Navigation Goes Silent

The LG G5 runs Android, and Google Maps relies on two separate audio channels: the media stream (for music, videos, and navigation prompts) and the notification stream (for alerts). When navigation voice fails, it’s rarely a hardware issue. The most common causes are:

Muted navigation voice inside the app – Google Maps has its own voice volume slider that can be turned all the way down.
Media volume set to zero – If you last used headphones or a Bluetooth speaker, the media volume may have been left at 0.
Do Not Disturb mode – This can block navigation prompts if set to silence all media.
App permissions – On Android 6.0 and later, Maps needs microphone and notification permissions to play voice guidance.
Outdated app or OS – A bug in an old version of Google Maps or the G5’s firmware can break audio.

Quick Fixes to Try First

Start with these three checks, which resolve most cases:

Check the in-app voice volume. Open Google Maps, start navigation to any destination, then tap the speaker icon on the bottom-right of the map. Select the Unmuted option (not “Mute� or “Alert Only�). If you don’t see the speaker icon, tap the map once to bring up controls.
Raise media volume. While navigation is active, press the volume-up button on the side of the G5. The on-screen slider that appears controls media volume, not ringer volume. Make sure it’s at least halfway.
Turn off Do Not Disturb. Swipe down from the top of the screen with two fingers to open Quick Settings, and tap the Do Not Disturb icon (a circle with a minus sign) to disable it.

Check App Permissions and Battery Settings

Android 6.0 (Marshmallow) introduced runtime permissions, and the LG G5 shipped with that version. If you denied Google Maps permission to access notifications or the microphone during setup, voice guidance won’t work. To fix:

Go to Settings > Apps > Google Maps.
Tap Permissions and ensure Microphone and Notifications are toggled on.
Also tap Battery and select Unrestricted (or “Not optimized�). LG’s aggressive battery saver can kill background processes that deliver voice prompts.

If you recently updated the app, permissions may have reset. Re-enabling them is harmless and often fixes the issue.

Clear Cache and Update the App

A corrupted cache file is a frequent culprit. To clear it without losing your saved places:

Go to Settings > Apps > Google Maps > Storage.
Tap Clear Cache (not “Clear Data� – that would delete offline maps and history).
Restart the phone and test navigation.

If that doesn’t help, check the Play Store for a Google Maps update. Google regularly fixes audio bugs, and an outdated version on the G5 may have a known issue. Also ensure your LG G5 is running the latest Android version it supports (Android 7.0 Nougat). Go to Settings > About phone > Update Center to check.

Bluetooth and Audio Routing Issues

If you use a Bluetooth speaker, car stereo, or headphones, the G5 might route navigation audio to a device that’s not connected or is muted. Try this:

Turn off Bluetooth entirely and test navigation through the phone speaker. If it works, the problem is the Bluetooth device’s volume or its audio profile.
On some car stereos, the “media� audio channel is separate from “call� audio. Ensure the car’s media volume is turned up, not just the call volume.
If you have a smartwatch or other paired device, unpair it temporarily to rule out interference.

When All Else Fails: Reset App Preferences

Resetting app preferences restores default permissions and background restrictions for all apps, but does not delete any personal data. This is a more aggressive step, so try it last:

Go to Settings > Apps.
Tap the three-dot menu (top-right) and select Reset app preferences.
Confirm, then restart the phone.

After this, you’ll need to re-grant permissions to apps you use, but it often clears deep-seated conflicts that individual app settings don’t.

Frequently Asked Questions

Why does Google Maps work but only speak through the earpiece?

That happens when the phone thinks a call is active. Check if the G5 is stuck in “call mode� – toggle Bluetooth off and on, or restart the phone. Also check if the speaker icon in Maps is set to “Alert Only,� which plays prompts through the smaller earpiece speaker instead of the loudspeaker.

Will clearing Google Maps data delete my saved places?

Clearing cache does not delete saved places. Clearing data (or “Storage�) will remove offline maps, search history, and some preferences, but your saved places are tied to your Google account and will return when you sign in. Avoid clearing data unless you’re comfortable re-downloading offline maps.

Does the LG G5 have a known hardware issue with navigation voice?

No widespread hardware defect specifically affects navigation audio on the G5. The phone’s speaker and audio jack are reliable. If you hear music and notifications but not navigation, it’s a software setting, not a hardware failure.

Can I make Google Maps speak through the Bluetooth while music plays?

Yes. In Google Maps settings, go to Navigation settings and select Play voice over Bluetooth. This ensures prompts interrupt music rather than playing on the phone speaker. If that option is missing, update the app – older versions didn’t have it.

Why is the navigation voice volume separate from media volume?

Google Maps intentionally uses the media stream so you can adjust music and navigation independently. However, if you set media volume to 0 while listening to music, navigation goes silent too. Keep media volume above 0, and use the in-app speaker icon to fine-tune navigation volume.
