When I give it a vocal command, "home", the navigation responds that it cannot do it and I should delete the "poi's"
I never entered any poi. What am I supposed to do to get it to navigate to my home? (Home is programmed)

if your home is programmed then in the lower left hand corner of the screen will be a small icon like a flag symbol, if you push that it will program a way to home.

Of the many times I have tried to say "Home" to the RX400h Nav, it has only worked perhaps 1 out of 10 times. I have also tried varying the pronuciation of home to Homeee and Homma with some limited success. What has worked is to program in a Quick Access point for the home address and say to the Nav "Quick Access 1" instead of "Home" The quick access points seem to be understood by the Nav in better than 9 out of 10 tries.

After several attempts at saying "Home" my nav system finally gave me a list of chinese resteraunts. I picked one and had a great meal. Had to find my own way home.

Instead of using "Quick Access 1", can you have something like "My Home" or "Home Sweet Home". If this is possible, it might work better when there are more syllables in the voice-print to distinguish from other entries in the database.
 
Just a thought-- since I'm very familiar w/ Voice Recognition technology but not yet an owner.

I tried your other phrases for Home, but it only recognizes "Home" or "Go Home". It reliably recognizes these two phrases if the climate control system is turned off and there is no other interfering noise. Under noisy conditions it just does not work reliably.

The touch screen on my navigation system is not responding to touch. Other functions in the system continue to work, including through voice, but no functions on the screen respond to touch commands.
 
Any thoughts or will this require a service call.

The screen is not blank, although I can turn it off with the voice command. It will show any of the screens that correspond to the buttons below, but will not respond to touch. I brought it to the dealer and they are trying to figure out what to do. Sounds like a major fix is required.
 
Very disappointing for a vehicle with just 3,500 miles.

If you look into the Navigation Quick Guide you will find some of the Voice Commands that the system will recognize. In regards to HOME try using "GO HOME" for a higher success rate. Lastly, I always recommend rolling up the windows and quieting the interior before making a command.
