03 seville sts navigation problem
 

I have a 2003 seville STS with bose/navi, and the navigation seams to be lacking in complete dirctions when I put in a destination....I cann see the destination on the map, but the navi only gets me so far and says"you need to get the rest of the way by looking at the navi map", instead of giving me directions all the way to my destination...is this normal?
