Navigation system the installed navigation system on Toyota Sienna models does not indicate the destination side of the road. In other words, there is an audio indication "you have reached your designation" but it does not indicate which side of the road it is. This is a real serious safety risk -- suddenly the driver has to try to change lanes, slowing down, to try and find the destination, thereby risking being rear-ended while trying to maneuver out of the current lane. All navigation systems should be required to state this information. Even hand-held gps systems give this vital information. Toyota hq said there is no plan on fixing this problem.
