Garmin Streetpilot 2820
I have a Garmin 2820 with the XM add on. This is attached through a Baehr Comm. system for K1200LT. When using the volume control on the touch screen, the increase/decrease steps are in 10% increments. This sometimes makes the output either too high or low. Does the Navigator III have this XM attachment and therefore the same issue.
