Condition / Concern
A customer or dealer may have questions or concerns about the Text Messaging feature
available on some newer GM infotainment systems. Systems with Apple Carplay or Android
Auto Have texting available when in use through the app.

Recommendations / Instructions
Text Message Alerts are available on all 2015 models equipped with MyLink, IntelliLink or
Cadillac CUE (excluding Sonic, Spark, Spark EV and Trax; Texting for 2015 Escalade/ESV,
Sierra 2500HD/3500HD, Silverado Heavy Duty, Suburban, Tahoe and Yukon/Yukon XL models
is dependent on having RPO AVF).
NOTE: Text Message Alerts are also available on select 14MY vehicles: Chevrolet Camaro,
Cruze, Cruze Diesel, Equinox, Malibu, SS, Traverse and Volt; Buick Encore, Enclave and
Verano; GMC Acadia and Terrain.
Text Message Alerts are offered when the system is paired with a Bluetooth device that
supports text messaging. Commands can be initiated using the text message icon (varies by
vehicle) on the touch-screen display. When a text message is received on a paired,
compatible phone, this system allows the customer to:
Display the incoming text message on screen when the vehicle is stationary or a
passenger is detected (if equipped with Passenger Lockout).
Listen to the message read aloud over the audio system.
Choose from a list of pre-defined responses when the vehicle is stationary or in motion
(with select vehicle and phones).
Note: This feature is not designed to replicate the text messaging functionality found on
your phone. Functionality varies by vehicle, phone make, and model.
In order to use Text Message Alerts, your compatible phone must be paired with the
infotainment system. For most devices, you must take an additional step during the pairing
process to enable Text Message Alert functionality in the vehicle. This step varies by phone
make and model, but generally, you can follow the process below.

IPhone devices
Pair your iPhone with the system
On your phone, select settings>notifications>messages. Make sure that "Allow
Notifications" and "Show On Lock Screen" are both selected on.
On your phone, within the Bluetooth SETTINGS menu, select the “i” icon next to your
vehicle name in the device list and enable SHOW NOTIFICATIONS
The feature will be enabled on your next ignition cycle (wait at least 3 minutes after
engine shut off)
Note: Your device should remember your notification preferences when it reconnects in the
future.
Text Message Alert functionality varies by phone. The following functionality is specific to
some IPhone devices:
Text messages CANNOT be responded to using the radio system for iPhone devices;
they can only be received
Only text messages received during the current drive cycle are accessible using the
radio system
If the user’s phone is currently showing an open text message screen/app, the user may
not receive an alert for new messages in the active conversation through the radio
system

iPhone's have to have iOS6 or later version so that incoming messages can be displayed
on the car's dashboard and/or read aloud by the car's computerized voice.

Android Devices
Pair your Android device with the system
During the pairing process, your phone may ask you to allow the vehicle to access your
device’s contacts and M.A.P. (message access profile). You must agree to both in order
to use Text Message Alerts
Note: Select “ALWAYS ALLOW” on your device to remember your notification preferences in
the future. Some Android devices require the user to drag down the notification page (swipe
down from the top of the screen) in order to complete these steps.
