Oh wow, you're quick! I managed to work it out by using "O" to drop a pin, and then "U" to route to it from current location.

Only issue is the blue line of the route seems to disappear momentarily every few seconds. Normal?

And scrolling across the map slowly can be a bit difficult to control. Is there a way to customise this?

Edit: also press 'n' hold menu (for routing) doesn't seem to work in portrait mode.
