Yeah, there’s no telling the guys on busy channels to switch up two or down one or whatever. It automatically finds an open channel and switches you when you accept the call. Plus there’s no need to try to raise the other guy, it dials them and hails them so if they pick up you know it without worrying if they can hear you or not. You’ll know. Heck my ring is so loud I can hear it at 40 mph.
A piece of advice though, learn to use it first because, um, I felt stupid fumbling around it. On my radio its really simple though, very intuitive… and cool to use, too.
