I got very frustrated with my iFinderGO at first but after putting it into "advanced mode" I found that by pressing ENT once it produced an understandable "create waypoint" menu. I entered a couple of waypoints by typing in the Lat Long and found that pressing FIND allows you to select and look at them. The tab at the bottom of each waypoint page scrolls horizontallyallowing you to choose "Go To", "Edit", "Delete" etc. Once you are in goto mode you can change page to a normal GPS screen showing course, distance, XTE etc.
The trip function (MENU, MENU, UTILITIES, Trip Calculator), is where you switch on /off and re-set average speed and distances etc. Switching the backlight on by pressing the PWR button for 2 secs improves screen visibility but you have to be careful as pressing it for 4 secs turns the unit off.
BTW the term Lowrance use for VMG is "closing speed" which seems reasonable.
With the (extra cost) connection lead plus USB/Serial coverter dongle mine transmits NMEA data into Maptech and Seapro Lite with no problems.
The amazing battery life of at least 48 hours came in very useful recenltly when our Raymarine on board plotter kept switching itself off due to low voltage.
In conclusion I would give this unit maximum points for value (you can get them for £50) and fantastic battery life with 2 x AA batteries - probably the best for any handheld, but it is let down by all the USA hiking stuff cluttering up the menus and the screen is very small and not very bright. However it is probably ideal for the grab bag (with the AA Batteries in a separate sealed package).
