See, that's why you need the smartphone so she can put the correct store in the navigation system and let the phone nag at you to turn here and there until you get where you're going.
I have a built-in navigation system in my head. Plus, I don't want to hear her voice when I am driving. I get wound up as it is with slow drivers etc. I don't need to listen to her on top. (And in the UK, you are not allowed to use a mobile whilst driving.)
Her indoors bought me a sav-nav about 3 years ago. It is still in its box. I only drive to places where I know the route, so there's no need for a sat-nav etc.
