Just got the 2019.40.50.7 update, and it seems to have “lost” all the nav cameras. No lane markers or nearby cars now show up at all on the touch screen, and therefore the blind spot warning, etc from previous updates are no longer working. Still have radar proximity “arcs” but that is all, while driving (b/u camera still works in reverse). I do not have any autopilot upgrades, etc., just the standard LR M3, delivered August 2018. I have rebooted the screen twice and no change. This seems like a significant safety issue. Anyone else experience this, or know of a fix? If no fix, can Service set me back to the previous software version? Thanks for any help!
