I had a screen freeze today whilst reversing and had to reboot on the move which was slightly unnerving. I was trying to work out if there were any controls on the screen that would be essential to driving and headlights were all I could think of. I have them on auto, so do they stay on when you do a reboot (it was still light when it happened)? Also, I have to say the emergency lane departure seems very over sensitive. It was activated when I was miles away from a parked car. Hopefully this will improve.
