1) Have you verified the software
update (simple I know, but you never know!)
2) You have to navigate to a way-point, once you do the laylines show up.
I am not sure about racing
mode, as mine are always there when I go to a waypoint. I use the built in polar for my boat
EDIT: I am on 3.09 with just laylines. It seems the July 3.10.xx has a race
mode. I guess another update is in order.
