Alexa works fine in my '15 LS handling basic things like playing Amazon Music, weather, etc. But I am not having any luck with navigation. Alexa will find what I ask for, say a nearly coffee shop. She will display a list on screen of her findings. I can either ask her to "take me to the first/second/third on the list' or choose it via the touchpad, Either way, I hear a ding and the map comes up. But then everything stops! Navigation does not start...I don't see any kind of "continue" button and no audio instructions on how to proceed. My choice is not shown in my "Saved Destinations" so I don't know what is going on. I was hoping with the future death of 3G Telematics that Alexa might be a suitable (albeit limited) alternative for a full-on CarPlay integration. Any help getting the nav working is greatly appreciated!
