There is another thread, but, many of the older phones running Android 2.3, that support the MAP Bluetooth profile, will be full function with sync on the 10-12 model year SHO's. I'm not sure about Apple devices, but, if you haven't updated the OS in 4 or 5 years, they should work.
I'm not sure about 13+ as they continue to get sync updates and might be compatible with the changes Google put in versions 4+ of Android.
More details for those of you interested... I went around and around with Motorola, Google Android developers and Ford, only to find that Google changed the 'handshake' and AT commands for the Bluetooth protocol regarding MAP. That protocol within the Bluetooth stack is what's used for the texting.
Ford says that sync worked on devices at that time, and they cannot change the connection protocol due to hardware constraints.
Google and Motorola say tough luck.
Hopefully, Google in all their infinite wisdom, doesn't make more changes to break other, currently working functions.
