Google Maps on the Samsung Galaxy S5 is great to navigate by car in traffic. Real time route calculation and information on congestion and other traffic conditions make this useful app to a daily companion. If you make use of Google Maps on your Samsung Galaxy S5 and in conjunction with a Bluetooth hands-free car, then it may happen that you cannot hear sound announcements from Google Maps navigation.
If this is also the case with your Samsung Galaxy S5, in conjunction with Google Maps and a Bluetooth hands-free car, then we want to give you two important notes here that perhaps are the reason for the lack of sound:
1. Voice guidance is activated?
Have you started on your Samsung Galaxy S5 the Google Maps navigation, please check whether the voice guidance is active. For this purpose, after starting the navigation in Google Maps tap at the bottom right on the vertical three-point symbol. There are now opening up four tiles. One of them must be set at "Mute voice guidance". If this is not the case and you can see there "Unmute voice guidance", please tap on that tile.
2. Is the voice guidance transmitted on the radio of the car?
It may be that the voice announcement from Google Maps is streamed from your Samsung Galaxy S5 directly on the car radio. Usually the radio is off so of course no sound is heard then. So please check your vehicle radio, whether "Bluetooth" is selected as a media. Only in this way the voice guidance of Google Maps can be heard over the vehicle's speakers.
These are usually the most common reasons why you do not hear any sound when navigating with Google Maps, the Samsung Galaxy S5 and a Bluetooth hands-free kit.
