I have just purchased a Focus Titanium with the Sony Sat Nav as an extra. This is my first Sat Nav so finding out what it does. In the top lright hand corner of the screen there is a small circle with an arrow head inside. This changes direction when you are driving. What is this telling me?. I thought perhaps it related to direction of travel but this does not alway apply. Nothing in the manula I can see

Perhaps North or Perhaps final destination relative to your position.

Id go with Compass

Yep Compass pointing north
