Typing into the search bar may not be necessary, if your device supports voice input and has this option enabled in the device and/or keyboard settings. On iOS, you need to give Sygic permissions to access both the Microphone and Speech Recognition. The app will show a notification when you tap the microphone and once you provide the permission, the feature will work.
To use the feature, just tap on the search icon and then instead of typing via the on-screen keyboard, tap the microphone icon on the right side of the search bar (if it’s not there, this feature is not available or not setup in your device). Wait for the prompt telling you when you can start speaking, and then you can enter the street or place name into the search field by speaking it instead of typing.
