I have my phone connected and I get the txt messages on the screen but when I ask voice command to reply for me she says that my phone is not a compatible phone....
I have an Iphone 8 plus with lasted IOS....
Notifications are on on the Bluetooth settings...

 

try just activating SIRI to send a reply txt

 

Thank you!, yes, through siri it's no a problem, but for siri I need to reach out for my phone and press the home bottom...
I wanted to use the voice I have in the wheel... I am going to the dealer this week to find out if they can do something...

 

you didn't say whether or not you can send a normal text, only said reply.
My iphone 8 allows lexus to send text message, as long as sendee is on contact list.

Does reply work for others? I will test it later.

 

Hold the "off hook" (button for answering the phone on the steering wheel) to connect to siri

 

yup, took me over a year to realize that...

 

^lol, that sucks bro
