The Lexus sat nav seems unbelievably complex to operate. Can anyone tell me whether the Lexus Standard Navigation system will automatically offer re-routing options around traffic delays? The Tomtom in our previous Mazda Mx5 did although there was an annual subscription to pay for Live Traffic Services and our portable Garmin dynamically re-routes, however, I cannot for the life of me figure out whether the Lexus Navigation offers this? The local dealer cannot answer this query either !
