when i use my navigation system it seems like i have too many routes. for example. im leaving my house and the navi says to go on the freeway 78W...i go 78 E. now i know how to get there so i go 78 E. now driving down 78E, at every single exit, the navi is telling me to take and turn around..all the way down to the destination. whats is going on? i thought it adjusts and makes me a new route instead of the one it insist i use.
