I was poking around the NAV system this morning, and found that you can edit the icon displayed for the "My Places" list of locations. This is good as I sometimes get tired of seeing all those flags when I'm trying to find some place on the map that is not one of my saved locations. It's also nice because the 5 or 6 "quick access" destinations can each have separate icons, giving me a chance at rememerbing which is which from the destination screen. The part that really gave me a chuckle, though, is the last page of icon choices "with sound". I wondered what the heck that would mean, but gave it a try, by setting one for the office. So sure enough, when I was almost at work, a little music box jingle began to play. I can't think of a practical use for this at the moment, but probably someone could make use of this? You, in effect, can have a sound play every time you approach a certain location. (One is "with direction" which I didn't test, but I assume it would only play if you approach in the selected direction?) Though the NAV system could use a lot of improvements, it is not only useful but endlessly amusing to me. Anyone else discover functions that they particularly like, or are entertained by?
