Going a stage further than the speaking keyboard found on all S-Series models (itself a convenient feature when inputting road names, towns and postcodes), the S90i is equipped with text-to-speech (TTS).
Simple in concept but a huge leap forward in convenience and safety, TTS enhances audible directions by speaking the actual road names. In doing this it’s easier and more intuitive to follow, allowing you to concentrate more on the road ahead while being guided quickly and easily to your destination.
