Ford Sync 3 USB connection broken with IOS 11.2.5

After updating IOS to 11.2.5 usb connection to Ford Sync 3 no longer works with native Sync 3 OS running.


With the Ford Sync 3 system audio and maps can be either Apple Carplay or the Ford Navigation and Music program. If one is to run the native Ford Music and Navigation program Apple Carplay must be disabled.


The problem is after updating IOS, the USB connection for the Ford Sync 3 music app no longer functions and even blocks the ability to use the Bluetooth connection to the iPhone on the same app. Siri is down at this point also. One must disconnect the USB connector to allow the use of bluetooth to connect to the iPhone for the Sync 3 music app. After the bluetooth connection is established, the USB connector can be reattached to charge the iPhone and use Siri. Also, the button to select USB for a music sources reappears on the Sync 3 Music Source page, but if you select it, it locks out the iphone again in both USB and bluetooth. Then you have to disconnect the USB connector again so you can select Bluetooth again.


This problem was replicated in two different Ford vehicles with the Sync 3 system.


If Apple carplay is enabled that system works fine.


Prior to IOS update to 11.2.5 everything worked fine.

iPhone X, iOS 11.2.5, Ford Sync 3

16 Fiesta ST. I have same issue and can confirm developer ios 11.3 will fix the issue. I had to remove 11.3 from my phone. I need to use my phone (6S) camera for work and copy pictures from the phone to a Windows PC. 11.3 Fixed Sync connection and broke the connection to download photos out of my phone into my PC. Just FYI. Going back to 11.2.5 fixed pc connectivity and re-broke ford Sync. Frustrating.

Okay, I take back what I said about it not happening on Sync 3 v2.2. I hadn't been in that car in a while, but I just tried it, and sure enough, it shows the same incorrect behavior as v2.3. But I did try the iOS reboot on this car, and it too started working perfectly until I unplugged and replugged.

I have a C-Max Energi, which in California, means I can use the HOV (carpool) lanes even when there's just me in the car. The Sync navigation takes this into account and will adjust the route for using these lanes. None of the apps I've tried (Google Maps, Apple Maps etc.) have this feature.


FYI, the 11.3 beta did get my phone working again. The only thing was I had to delete and re-add the phone in the bluetooth configuration in Sync.

@pupk What you describe with AppLink also persists in 11.3 Beta 2. I have had this same issue with mobile application support being spotty at best on three different Fords and Lincolns over the past few years, so it seems to be pervasive going all the way back to the horrible Microsoft-engineered Sync 1.


Other users may also be able to verify that when an app icon disappears, which usually means that cover art will also do your fault to the Ford generic images, or disappear completely, or show the incorrect art for something completely unrelated. And when that happens It’s generally not long after that the connections which is to Bluetooth and the button for USB becomes unresponsive until you unplug and re-plug the device.


Based on my personal experience with every version of Sync, it seems that Apple doesn’t vette Ford connectivity problems properly before releasing a new iOS update, and over the years I have found Ford to be completely uninterested in fixing These pervasive issues. I love the cars, but I think this is inexcusable. Any other car brand I have owned, and the cars belonging to friends I have connected to universally work perfectly with my iPhone.


Make no mistake that this is a problem that originates with Ford’s implementation. Apple bent over backwards for many months working with me one on one to try to solve these problems, but Ford corporate would not return messages to me, and my dealer basically told me I was crazy And that there was nothing they could do and no one has ever complained about any of these problems before besides me. I think everyone in this forum knows that is not true.

I have this exact problem as well after updating to 11.2.5. My Lincoln dealer is no help at all. When I bought my iPhone X it worked great in the car up until the update. I also had exactly the same problems with an iPhone 7 Plus in this same car. Worked directly with Apple Support for several months and they determined my phone and software were fine and that it was s Ford issue, which of course Ford denied. This phone works perfectly in my Range Rover and in other car brands belonging to my friends.

I have exactly the same issue with the Sync3 fitted on my Ford Kuga (EU version) manufactured in 2017. Apple must resolve this issue as soon as possible!
Hope that Apple will fix it prior to 11.3 being released (planned for next spring..)

Ok for immediately upgrade to iOS 11.3 public Beta.. but I think that it would be better to have an official final release to solve this bug.. (prior to 11.3)

Same issue on a 2017 Focus RS. USB and Bluetooth worked perfectly before updating the iPhone 7 to iOS 11.2.5

After updating, USB won’t work (“Unable to Connect to Media Device) and app link is broken, Bluetooth only works if the usb cable is not connected. Nice update, Apple. Let’s not bother to test the most basic of connectivity functions on the second largest car company in the US.

I Spent 3.5 hours on the phone with Apple support, heard numerous ******** excuses and blaming everyone under the sun for the problem, including me. Thankfully I found this thread and pointed it out to the senior Apple care advisor, who opened a case with engineering.

I’m so pleased with all the cute new emojis, almost makes up for the loss a useful function. Apple is becoming Microsoft.

I had same issue. Was able to update to IOS 11.3 beta. Everything was working fine for about 2 days and now both of my USB ports cannot even detect my USB for even a second. iPhone indicates that it’s charging for a couple seconds and then stops. Then starts and then stops (similar to when you have a broken USB cord) but I have tried with 3 separate cords. SMH fix this Apple.
