I have a 2015 Ultra Limited with 6.5 radio and NAV. I can use voice commands to "show map" or enter an address for a destination, etc. No problem. I can manually select "where to" and select "home", which is an address I entered and saved and it calculates the route and displays it. What I cannot do is to use voice commands and speak "home" and have it recognized. The book says I should be able to use the "home" command" and have it recognized and plotted once I have entered and saved the address under the home button. I have done the software upgrade to 19.1 or whatever the latest is now. Anyone have an idea what I'm doing wrong?
