Thanks to the support from OpenRoad Lexus Richmond. We installed another LukasDashcam LK-9390 DUO on the Lexus ES 350. If you did not get the Lane Departure Alert and Pre-Collision Alert on your car, LK-9390 is your best choice. Because it comes with those two functions and also it is the dash cam with the best picture quality in the market. More importantly, it is much cheaper than the car's option.
