I don't use a Garmin so I use MapMyRidedotcom. I map the ride then press elevation, it will show the grades with %'s.
I've heard you have to use at least a 1/2 mile section or it is too far from accurate. Many argue about accuracy but this way I get an idea of what I'm dealing with.
This is an image taken from the site with my snipping tool. (similar to google maps)
