I recently received an update on the Nav system which I am discovering included the items displayed on my HUD system. Previously when I approached a stop sign, the sign would show on my HUD. Since the update, no road signs display on my HUD. I do see a change in speed limit but that seems to be related to my GPS, not what the camera is viewing. I called the dealer and they stated that the camera has never displayed stop signs or any other signage. Really? I swear I used to see stop signs displayed when the camera detected the sign. Anyway, not a show stopper but it's crazy to lose features.
