I was driving and my nav screen changed to indicate I had a text message! I hit a button and a voice read the message. Awesome. I then discovered there are a bunch of automated replies already in place, or you can make your own. I selected one of the replies and hit send, and got an error message that only said it was an error. My phone was hooked up to the navi v ia bluetooth. The message came in fine. I tried to reply with the vehicle stopped and moving. What am I doing wrong? I think I have looked at all of the settings.
