Yeah the new update fixes the dreaded black map tiles waiting for the internet to load (previously not a problem with no internet, or fast internet). Now should work really well on bad internet too (the kind that times out but takes 10 seconds before it gives up and moves onto the next tile).
Probably dropping a user waypoint using the little teardrop button at the top is what you are after to log positions (it spits one out under your present position. Also useful for SAR's or a variety of applications).
