I found out what I´m was doing when the guiding works for me. I was going to the route magnet menu and press the button for set I get guiding in non guiding area. That menu with route magnet are only available when you have put in an address an push the button för guiding. When you put in the selektor knob you get a menu and if you scroll down you find route magnet. It only guide me with voice now the arrows dont work but the first time I got guiding the arrows worked.
