With less background noise, your conversations will be even clearer. * Sound Boost - A built-in 2 watt speaker brings quality audio to your car. Hear hands-free calls and navigation instructions loud and clear with Sound Boost. * Easy-reach answer and reject buttons - The easy-reach answer and reject buttons work even when your phone is not docked.

The spoken instructions take you through step-by-step and give feedback such as "phone connected".
