It's not Sync's fault altogether, it was the last Android OS rollout to 4.4.2 or 4.4.3 (Kit Kat) depends on the phone that disabled the text feature to Sync.
Well at least for me! It worked great for 3 1/2 years until this past spring.
Now I understand that when an OS rolls out, it's up to companies (Ford) to check their software to see if they need to update their data base.
And make the appropriate updates and distribute them in a timely fashion!!!!!!
I started with calling Verizon, of course I'm getting the blame game!!!
Called Motorola Tech support. Blame game!!!
Called Ford Sync, Blame game to!!!! (it's phone depended).
Probably won't get anywhere because it cost money to update data bases (Candidate List). LOL
So if you want text working it's up to you to spend the money to buy a new phone that Ford says is tested and working. Yeah Right. LOL
Here's the Link to the candidate list:

Note: the Samsug S5 it not listed, probably too new.
All in all, I do blame Google for ******** this up on my phone!!!
