Platform: PS4 (base console). Issue: When LZB is enabled but not active, the 'B' light does not illuminate, the distance indicator shows '00' and the speed restriction display shows '000' When LZB takes effect, both the 'B' and 'U' do not illuminate. The distance and speed restriction displays still both show a 0 value. The current speed does not display on the speedometer. When adjusting dial or indicator brightness, the distance and speed displays both become blank. In short, LZB does not display at all on the desk on a base PS4. LZB itself functions no problem and displays correctly on the HUD.
PS5 Same happening for me. However, the 8 cam trick does fix it so that B is lit up when not in use. I haven't tested LZB control after the 8 cam trick, though.
