2019 FORD FLEX USB port

AppLink Issues
Possible solution(s)
Possible cause(s)
Issue
Make sure you have a compatible smart-
phone; an Android with OS 2.3 or higher or
an iPhone 3GS or newer with iOS 5.0 or
higher. Additionally, make sure you pair and
connect your phone to SYNC 3 in order to
find AppLink-capable apps on your device.
iPhone users must also connect to a USB
port with an Apple USB cable.
You did not connect an
Applink Compatible
phone to SYNC 3.
AppLink Mobile
Applications:
When I select
"Find Mobile
Apps," SYNC 3
does not find
any applica-
tions.
Make sure you have downloaded and
installed the latest version of the app from
your phone's app store. Make sure the app
is running on your phone. Some apps
require you to register or login to the app
on the phone before using them with
AppLink. Also, some may have a "Ford
SYNC" setting, so check the app's settings
menu on the phone.
AppLink-enabled apps
are not installed and
running on your mobile
device.
My phone is
connected, but I
still cannot find
any apps.
Closing and restarting apps may help SYNC
3 find the application if you cannot discover
it inside the vehicle. On an Android device,
if apps have an 'Exit' or 'Quit' option, then
select it and restart the app. If the app does
not have that option, select the phone's
settings menu and select 'Apps', then find
the particular app and choose 'Force stop.'
Do not forget to restart the app afterward,
then select "Find Mobile Apps" on SYNC 3.
Sometimes apps do not
properly close and re-
open their connection to
SYNC 3, over ignition
cycles, for example.
My phone is
connected, my
app(s) are
running, but I
still cannot find
any apps.
On an iPhone with iOS7+, to force close an
app, double tap the home button then
swipe up on the app to close it. Tap the
home button again, then select the app
again to restart it. After a few seconds, the
app should then appear in SYNC 3's Mobile
App's Menu.

AppLink Issues
Possible solution(s)
Possible cause(s)
Issue
Switch Bluetooth off and then on to reset
it on your phone. If you are in your vehicle,
SYNC 3 should be able to automatically re-
connect to your phone if you press the
"Phone" button.
There is a Bluetooth issue
on some older versions
of the Android operating
system that may cause
apps that were found on
your previous vehicle
drive to not be found
again if you did not
switch Bluetooth off.
My Android
phone is
connected, my
app(s) are
running, I
restarted them,
but I still cannot
find any apps.
Unplug the USB cable from the phone, wait
a moment, and plug the USB cable back in
to the phone. After a few seconds, the app
should appear in SYNC 3's Mobile Apps
Menu. If not, "Force Close" the application
and restart it.
You may need to reset
the USB connection to
SYNC 3.
My iPhone is
connected, my
app is running, I
restarted the
app but I still
cannot find it on
SYNC 3.
Increase the Bluetooth volume of the
device by using the device's volume control
buttons which are most often found on the
side of the device.
The Bluetooth volume on
the phone may be low.
I have an
Android phone.
I found and
started my
media app on
SYNC 3, but
there is no
sound or the
sound is very
low.
Force close or uninstall the apps you do not
want SYNC 3 to find. If the app has a "Ford
SYNC" setting, disable that setting in the
app's settings menu on the phone.
Some Android devices
have a limited number of
Bluetooth ports that
apps can use to connect.
If you have more AppLink
apps on your phone than
the number of available
Bluetooth ports, you will
not see all of your apps
listed in the SYNC 3
mobile apps menu.
I can only see
some of the
AppLink apps
running on my
phone listed in
the SYNC 3
Mobile Apps
Menu.

General
Possible solution
Possible cause
Issue
SYNC 3 only supports four languages in a
single module for text display, voice control
and voice prompts. The country where you
bought your vehicle dictates the four
languages based on the most popular
languages spoken. If the selected language
is not available, SYNC 3 remains in the
current active language.
SYNC 3 does not support
the currently selected
language for the instru-
ment cluster and inform-
ation and entertainment
display.
The language

SYNC 3
SYNC 3 offers several new voice control
features for a wide range of languages.
Dialing a contact name directly from the
phonebook without pre-recording (for
example,
“call John Smith ”) or selecting a
track, artist, album, genre or playlist directly
from your media player (for example, "play

(phone, USB,

audio, voice
control and
voice prompts). SYNC 3 System Reset
The system has a System Reset feature that can be performed if the function of a SYNC
3 feature is lost. This reset is intended to restore functionality and will not erase any
information previously stored in the system (such as paired devices, phonebook, call
history, text messages, or user settings). To perform a System Reset, press and hold
the Seek Up (>>|) button while pressing and holding the Radio Power button. After
approximately 5 seconds the screen will go black. Allow 1-2 minutes for the system
reset to complete. You may then resume using the SYNC 3 system.
For additional assistance with SYNC 3
troubleshooting, refer to the regional Ford
or Lincoln website.
