I updated to Mapsource Version 6.5 some time ago, and noticed that Waypoints can now be subdivided into 16 different categories, as per the attached image. As I dont know what to do with these categories, so far I have just been saving waypoints without allocating them, but feel that there's probably a good feature here that I'm not using to its full potential.
I assume that you can change the Category names eg from "Category 1" to say "Hotels" but I don't know how. What do the rest of you do with yours ?
These categories only seem to exist on the computer ie if I search for a Wapoint in the unit, it doesn't ask me which category I want to search for. Does the unit just lump them all together? Someone here is bound to have all the answers.

You guessed right, I do use a SP3 and I have upgraded to the latest software, but it doesn't ask which category I want to look in when looking for a waypoint, unless I'm missing something there as well.
