Entune messaging with iphone

I have all of this turned on and I am able to get the messages and they are read to me, I am just not able to send any quick replies. I have a Iphone 6+ and new 2015 Sienna?? Any help would be awesome! Thanks in advance.

Just bought ours and the pairing work fine on 2 different iPhones. Be sure Bluetooth is on on the iPhone

It only works with IPhone 5C and 5S. I was hoping when I got IPhone 6, that it would be compatible with messaging. Nope. Just tried. I can't find anywhere that Toyota intends to update Entune

By adding the next to last (red) step to Toyota’s instructions, I finally got my Iphone6’s audio, phone, & messaging to work with Entune Audio Plus.

Radio: Press the Home button. Select the Setup icon. Select Bluetooth Select Add

Iphone Bluetooth settings: Select your Vehicle If necessary, enter the PIN, the passkey on the vehicle display, “OK’, or ‘Pair.’ On your iPhone select the "i” symbol to the right of the connected system and turn on "Show Notifications" In "Settings>Notifications>Messages," make sure that “Allow Notifications” and “Show on Lock Screen” are on. Disconnect/reconnect the phone using the vehicle’s multimedia system's control.

I have the same problem. I can get messages but can not send a verbal message through entune. I've set my phone to all the settings recommended. Any other ideas
