I tested today and my 2010 with LEX6, the low speed/stop cameras will not trigger if I'm in Vline mode. If I'm set to auto and I'm in some other screen other than Vline, then they trigger as they normally would. You also have to already be in some mode outside of the Vline before the switch would have happened otherwise it's lost. I will say though that i thought after I initially installed it that the slow speed cameras still worked. So, it's entirely possible that this is a feature that can be affected depending on which firmware and which model Vline you are running. I run an older firmware on mine because it's the only one that doesn't have consistent screen blackouts that i have to click a button to recover from. I haven't tried the last one or two new firmwares, but i tried about 4-5 of them after finding the one that works best for me and had to revert each time.
