I have the rear climate control option on my X. I felt the tint was not enough for Bahrain in which is 90% hot all year around.
So I install the Pre-cut out Solar Gard window film clear on front wind screen at 84% heat resistance and 35% tint on the front driver and passenger side to match the rear climate option installed. To make it even better I installed the Rear Sun Shades for BMW X5 show on the X5.world >articles > X5>interior.
Also I installed 100% silver mirror tint with 95% resistance on both of the Panoramic roof as well. I’ll post picture this weekend. We are currently under sand storm condition for the next few days.
