How much money ya got?
As yet I haven't used my GPS III which I use for sailing in an aircraft yet but unless you are desperate for a shiny new toy that makes the tea as well, I'd keep it simple so that you can use it for other activities.
Mine is fairly simple, you put in the waypoints and use it conventionally with features such as MOB (Man Overboard, crap on an aircraft but useful on a boat
) etc but I also use it for long walks with the dogs in an area I'm unsure of.
Raging debates on the merits of GPS on this board will show you where people stand but my only reservation with using a GPS with a moving map in an aircraft, is that it's possible to pay it too much attention and not enough of your map, aviating etc.
A wonderful tool but personally I'd keep it simple as it could become too distracting. At the end of the day all you want a GPS to do is tell you where you are and how to get to your next point - so keep it simple!
