There is guidance! It will route to your destination, with necessary turnoffs and time to each turnoff. In fact,as long as you set it up online and leave it setup, It works fine offline. I'm wondering if I made a mistake in picking up the selected route further along,because Maps sent me in the wrong direction to start with. Once I did pick it up it was fine, except instead of voice at changes of direction, I get a bonging sound. It's true to say you must stick to selected route once offline. Thanks anyway.
