With an optional XM satellite receiver and subscriptions, the Garmin GTN series can display NEXRAD radar, lightning data and other aviations weather information. It can also play satellite radio stations.
For pilots who want a fully integrated solution in a small, 2.64-in.-tall package, the GTN 650 is the perfect choice. The system combines GPS, COMM and NAV functions with powerful multifunction display capabilities like high-resolution terrain mapping, graphical flight planning, satellite weather, traffic display and much more.
If you personally own a Garmin GTN 650/750 or have experience with either of them I want to invite you to leave a commit below. Also if you have any question about either feel free to ask that as well.
