Tony, What you are referring to is what we call "flight following" if flying VFR here in the US. Our sectionals don't show center frequencies for a given area, but do show approach frequencies for sectors surrounding class C or higher airspace in metropolitan areas. I fly on avg. 200 hours a year (1400TT) don't use flight following (unless I have to, or to take a shortcut through some controlled airspace) because I suscribe to the theory that your two eyeballs are the best collision avoidance system you can have. There are plenty of airplanes in the sky without transponders or are below radar coverage that atc cannot advise you of. I use sectionals primarily for flight planning and keep them current in the airplane to be legal, and find the two Garmin GPS's on board provide more data and redundancy than do the maps. Both the III and the 196 will show center/approach frequencies for a given location, so I wouldn't find these useful to have on a map, because at the touch of a bu! tton I can get approach/center frequencies without fumbling with a map, if/when I need them. Think about it, when was the last time you saw an airline captain fumbling around with maps on their laps? Granted, its a different story since they're flying IFR and getting handed off appropriately. One of my pet peeves is pilots who call in to uncontrolled airport frequencies that clutter the airwaves with "cessna blah blah blah, 5 mi. south of whatever landing, any traffic in the area please advise". A few times I've keyed the mic and said quit using your mouth and use your eyeballs! So my point here is that we don't have these frequencies printed on our maps, IMHO if they were all they would do is add to atc workload and make pilots more complacent. I know a few pilots who hardly look out for traffic while flying. Be vigilant while flying, enjoy the view while you are, and you can easily prevent a close call, even when the viz is not so good, without talking to atc.
