Hey all,
Just wondering what everyone uses for a map system on there astros. Currently im using Maptech but its not highly detailed and not really up to date. I was watching a Youtube video the other day and noticed that one guy had aerial on his astro 220, is that possible or was i seeing things? thanks guys! mike

Not sure about the Garmin Astro 220, but the Garmin Astro 320 is supposed to have this feature, I believe you have to subscribe though.
