Some flavors of these selective films may add visible tint, too, but they are available with 70% visible transmission and 60% solar heat rejection, which in theory can also be used on the windshield, where darker tints are typically not allowed. Of course, the spectrally selective films are more expensive and harder to find, but it is good technology and worth the extra effort (really it should be built into the windows at the factory). Two example products are V-KOOL and 3M Crystalline, If you are concerned about GPS/cell transmission through the glass, the 3M film is not metal based like V-KOOL, so it will have less attenuation.
