I have an Avmap in my -7.
It performs very well and I am glad I purchased it over the Garmin, but as others have testified, if you know the Garmin menus, a Garmin would be easier initially........... but you soon find your way around the AvMap.
My decision was based on screen size and that is where it shines.
However, if I was doing it again, I would probably blow some more dollars on a third GRT as the NAV function and menu are simply the best.
