After setting the time in my sisters Jeep Cherokee I decided I should also connect her iPhone to the Uconnect system via Bluetooth. The Uconnect system will allow you to receive calls, dial calls, etc. verbally in your car so you don’t have to look a t your cell phone while dialing. The Uconnect system i activated by pressing the button below the rear view mirror in your Jeep Grand Cherokee and I assume that in most cases the button location is similar for other vehicles. Below are two images including a close up of the Uconnect button located to the far left of the buttons below the rear view mirror and a picture of the entire rear view mirror so you get an idea of the buttons location.
