Navigraph Charts and the GTN750?

[Howiefly13 30]

I just saw that a new version of the Navigraph Charts has been released.  I use the 750 in all of my aircraft and have never used the Navigraph Charts, because I use the 750 for all my navigation needs.  Is there any need or advantage to having the Navigraph Charts along with the 750?

Thanks a lot,

I fly exclusively GA, North America, and the Caribbean. For advance flight planning I use Skyvector, FltPlan.com. and FltPlan's FltPlanGo app for the iPad.  Those sites and the app have all the charts I need and then some.  The FltPlan Go app provides a live moving map on the iPad (Android version also available), including overlays of procedures (departure, arrival, approaches).  Those also without cost or subscription.  So I have not found the need for Navigraph charts.  FltPlan.com and its FltPlan Go app are limited to USA, Canada. and the Caribbean.
