Give your wheel a hand with the Motorola Sonic Rider Bluetooth in-car speakerphone. A simple solution for driving responsibly, Sonic Rider lets you give voice commands to make and take calls and send text messages hands-free. Hear more of your call and less of the road through the powerful 2-watt speaker with echo and noise reduction. Voice prompts tell you when you're connected, muted, or low on battery. And with 45 hours of talk time and five months on standby, you battery will last on even the longest road trips.
