It's easy for most Chevrolet, Buick, GMC and Cadillac customers to use hands-free technology. Bluetooth allows users to connect their mobile device to their vehicle and place and receive calls using steering wheel controls and voice recognition. The vehicle audio system allows users to hear the call through the speakers and respond using the built-in microphone. Once a phone is paired with Bluetooth, a customer's mobile device will automatically connect to the vehicle when the ignition is turned on.
OnStar Hands-Free Calling allows OnStar subscribers to make calls from their vehicle using voice-activated dialing. Subscribers simply press the white phone icon button to dial a number by saying the number aloud or to answer an incoming call. Hands-Free Calling, with its externally mounted antennae, is specially designed for better reception and fewer dropped calls in remote areas and pockets of limited cellular reception.
