I have had my OT+ for a year and live in Houston, TX. I purchased WeatherTech front window cover and leave AC in Auto mode. My car does not get too hot and now cools quickly. I also always leave driver seat AC on. My car is very comfortable on the 98 degree humid days now. Lexus GX SunShade...
Very good fit from WeatherTech and rolls up when not in use. Makes a huge difference in our summer heat when parking outside and also adds a level of privacy and security for outsiders trying to look in. Reflective silver finish.
I highly recommend new WeatherTech front windshield sun screen for GX 550 if you live in a hot climate. I have used for 3 weeks and it fits and works well.
