Not sure whether this is in the manual or not, but after 3000 miles I finally figured out why there were sometimes weird symbols on the map.
Turns out that if you ever use the "find points of interest near the current location" (I can't remember what its called exactly) - and pick a category, a symbol for that category will show up on the map everywhere there is a known place of that category. For example, if you choose "restaurants", you will then start seeing a crossed knife and fork symbol (I thought they were X's until I figured this out) all over the map.
The symbols for each category are different, but they do NOT go away with a power-down/restart. I think all you can do to "clean up" the map is to pick something there aren't too many of.
Now you know.
