Siri Eyes Free (for IPhone) – this will be available on select GM products in the 2015 model year. The app itself looks like an old-time broadcaster’s microphone.
o allows you to complete an array of hands-free tasks like composing text and e-mail messages, and storing contacts on your IPhone through voice commands, using your iPhone® 4S or iPhone 5 (and newer). This feature is only available to Apple IPhone users. (Siri Eyes Free is a feature of iPhone devices running iOS 7.1, so customers must be running this minimum operating system to use the service.)

Issues with texting on IPhones?:
1) Go into the IPhone settings screen
2) After the phone is paired with the vehicle, (Settings -> Bluetooth), click the blue info icon “(i)” next to the vehicle device name, and then click the tab to ENABLE “Show Notifications”
3) After doing step #2, remove the key from the ignition, open and close the driver’s door, and restart the vehicle
4) The text messaging icon on the home display should now be selectable, and it should prompt when receiving a text, with a variation of the options “Listen/View”, “Call”, or “Dismiss”

Most IPhone’s are able to use the in vehicle text function. However, with IPhones, the app will often only let you know that you have a new text message (received while you were in the vehicle), but, it will not let you respond through the auto text back/reply feature.
To respond using an IPhone, press and hold the “Phone answer” button on the steering wheel for about 3 seconds, which will engage your IPhone’s “Siri” voice command software. You then command Siri to read or reply to text messages. At this time, Siri can read and write text messages, emails (requires an active data plan on the cell phone, and phone may need to be unlocked for use, if a security code was set up by the phone’s owner), book appointments in your IPhone calendar, and also make notes in your IPhones “Notes” app.

If issues arise, always check to ensure the most recent software updates are installed on your device.

Wind Noise / Buffeting

At various speeds, as a window is lowered, passengers could experience a feeling of dizziness or disorientation associated with a “pulsing” sensation of the air inside the vehicle.

This issue, known as buffeting, can occur during both high and low speeds, and is often associated with a change in air pressure inside the vehicles cabin.

There are multiple causes associated with this effect, but it is mainly attributed to the precision streamlining of modern vehicle designs. Many vehicles are designed in conjunction with air flow tests performed under laboratory conditions, inside of a “wind tunnel”, which tests the effects of physical vehicle-body design, against airflow and aerodynamics, as it travels at different speeds.

The “buffeting” effect is caused by a sudden change in the aerodynamics of the vehicle, caused by the lowering of a window, which changes how the air is flowing over the surface of the vehicle. The effect can be corrected by raising or closing the offending window to correct the airflow. This effect can also be attributed, to a lesser degree, to the rapid exchange of hotter air inside the vehicle cabin, with the colder outside air, creating a vacuum effect.
