Before starting any drive where you're using Google Maps for directions, it's vital to make sure the app is functioning correctly, specifically, navigation prompts. After initiating turn-by-turn directions on your Android or iPhone, the last thing you want to worry about is Google Maps not audibly telling you where or when to turn, especially in an unfamiliar area.
When it comes to traveling from one location to another with the aide of your iPhone, ensuring your navigation app works as it should keeps you one step ahead of potential hassles. One feature often overlooked is audio settings, and while having no voice prompts is easy enough to ignore while walking or commuting, having no sound to guide you while driving can spell disaster.
