i work in a chandelery and in my opinion the globalmap 7200 is the best value for money plotter i have seen. the sreen resolution is the best i have ever seen and the brightness of the screen is great. we had one on disply and it was a great unit. plus lowrance are good with all their repairs and warranties, usually they just replace
as for the navplanner softwarewhen u buy the it they give you a second blank card to put waypints routes etc on. Plug it into the second slot and load the data through the system menu.
