I have adv nav as well. But this feature works only when you have navigation on, right? If the navigation is not on you don't get the augmented camera and therefore traffic lights won't be zoomed in? Also u get the camera on screen only if you are 500 yards within the next turn... in other cases traffic light zoom in won't appear.Yeah he's definitely right, I've got this feature which i assume is part of the advanced nav pack.
May be the new feature in FU3 will show the traffic light in the instrument panel just like it shows the speed limits.
