Hands-Free Calling is an OnStar feature developed to make in-vehicle phone calls without a cell phone.
All OnStar-equipped GM vehicles have a built-in wireless calling service enabling drivers to stay connected without using their cell phone. The feature works by assigning a vehicle a phone number.
One of the selling points of OnStar Hands-Free calling is that OnStar-equipped vehicles often have service coverage when a cell phone is not available.
Making A Call
To make a call, press the vehicle’s voice command button and follow the prompts.
