I've found Navigon on my iPhone an extremely useful pedestrian navigation tool with one exception. When I start a pedestrian navigation, the app either gives me no information on which way initially to head or the screen rotates around unhelpfully. I've occasionally gone quite a long way in the wrong direction before suspecting my error. I'm sure that I must be missing something obvious. Once I've got the initial direction right then I usually get where I intended. Any happy Navigon pedestrian users who can assist, please?
