Nokia :: 5800XM Lack Of A Built In Compass?

When in 'My Position' mode, the map moves to follow you as you move, however, it does not rotate. Is this due to the 5800's lack of a built in compass? If not, how can I enable this? Pressing the compass icon achieves nothing. Is there a way to manually rotate the map? Again, messing about with the compass icon has no yieled results.In navigation mode, when a route has been set, your current speed is shown, along with warnings when you go too fast, along with speed camera information. Is there anyway to activate these features without setting a route? I'd like these features when I'm out on a random drive, and have not decided a destination. E.g. having them in 'My Position' mode.Also, I do not have a data package, and so have A-GPS disabled, in Locations -> Positioning settings under applications, and have only integrated GPS activated. I've been wondering whether there is a charge for Network Positioning though? It seems as if all it does it find the mast you're connected to.
