Is there any way to train the voice command? When I use voice command to enter an address, it isn't even in the ball park. If I use the buttons to go to Navigate To then use voice it works well but from the VC button it adds extra digits to the house number then has the wrong street and wrong city. It doesn't matter what address I use it is just useless. I even tried something simple "Clear Route" I got "Command not recognized" then I said "Cancel" and got the response "do you want to clear the route?" It's lucky I couldn't reach my gun.
