Possible solution
Replying to text messages using SYNC 3 is
not supported by iPhone.
Text messages from WhatsApp and Face-
book Messenger are not supported.
Your cell phone must support downloading
text messages through Bluetooth to receive
incoming text messages.
Because each cell phone is different, refer
to your device's manual for the specific cell
phone you are pairing. In fact, there can be
differences between cell phones due to
brand, model, service provider and software
version.
Possible solution
Disconnect the device from SYNC 3. Try
switching your device off, resetting it or
removing the battery, then reconnect it to
SYNC 3.
Make sure you are using the manufacturer's
cable.
Make sure to correctly insert the USB cable
into the device and your vehicle's USB port.
Make sure that the device does not have
an auto-install program or active security
settings.
Make sure your device is unlocked before
connecting it to SYNC 3.
Make sure you are not leaving the device in
your vehicle during very hot or cold
temperatures.
