This isn't true. iPhones can pass text messages through to Sync / My Ford Touch. Mine works fine on a 2015 with My Ford Touch. I have an iPhone 6S and I don't have Apple Car Play.

Couple things to check:
1. On your phone, go into Settings / Bluetooth and click the (i) information circle next to SYNC in your Bluetooth device list. Make sure "Show Notifications" is toggled on.
2. On your iPhone, In Settings / Notifications / Messages, make sure "Show on Lock Screen" is turned on.
3. Your phone has to be locked in order for messages to get passed thru to SYNC. So, if you are using your phone for music, navigation, calls, or anything else that would have it unlocked, SYNC will not get a new incoming message. Personally I find this odd but that's how it is. Apple is using the "lock screen notification" as the trigger to pass notifications over Bluetooth. That's just how iPhones work.

If any one of these settings are not configured correctly on your iPhone, the phone will not pass incoming messages to SYNC.

Hope this helps!

This is incorrect. My 2017 will read text messages received on my iPhone 7 over Bluetooth.

 

Well you most have some thing different in settings. Mine will not although I typically plug it in and everything I have seen online shows it does not allow it. Also for anyone who ever watched videos on you screen via apple CarPlay and YouTube that feature will disappear with the ios11 update being released soon.

 

Check my post #11 above for the proper configuration. You should be able to get this to work in 3 easy steps.

If you're referring to iOS 11's "Do Not Disturb While Driving" mode, then you are correct. Enabling that will prevent messages from being passed over bluetooth. However, that is an optional setting and by all accounts iOS 11 should still be able to pass messages to SYNC over bluetooth with the right configuration.

 

I don't want to speak for others, but if what I am reading is correct (which sounds similar to my issues), the devices were working just fine and as designed up until recently. No settings have been changed or altered.
The instructions above are great for those trying to get it working initially.

 

This...It just quit working.

 

Sorry guys, I should have clarified. Mine quit working a few months ago too. And I also could not figure out why. After some research I realized it was because I disabled lock screen notifications. I didn't expect that to have any impact on the SYNC messaging feature but it did.

My advice, even if you didn't manually change any settings on your phone, is to double check the settings anyway, especially #1 and #2. I would assume that message notifications continue to come up on your iPhone lock screen even after your SYNC messaging quit working. If that is not the case, then that is probably the first place I would look. Lock-screen notifications are the trigger that sends messaging through the iPhone's bluetooth signal, and the Bluetooth connection has to be configured to allow Show Notifications to pass through.

If none of that helps, next thing I would try would be to delete the paired device from both the truck and the iphone, then shut down and re-start both and repeat the pairing process.

 

Not true, I get texts when not using CarPlay. Sync will read the texts, no issue.

For the OP, delete the phone from sync and add it back in.

 

That's not true.

Under Bluetooth settings, tap the I next to the device name and pick "show notifications".

 

Not ture. For 4.5 months mine gave a text notification, and would read text to me and I have not connected to apple car play.

Show notification is on. First thing I checked.
Show on locked screen is also turned on

Worked fine until a week ago or so.

Yep mine did work fine until a week a go or so.

The above is how my phone is set.

I cant figure out what changed or why it changed. Phone has not changed.

Did truck do an automatic update?
