I think it will depend a lot upon where you live.  Here in Arizona it
filled in a lot of blanks in freeways, etc. that we had in an earlier
version.  I don't know what your version does, but I liked the change
where it would navigate in areas that were not digitized.  My earlier
version just drew a dotted blue line from the last digitized road to
the target.  It was worth it to me.
