My installer was worried the tint installed on the inside might interfere with the circuit in the panoramic roof, so we installed Windshield Protection Film on the outside, which also reflects 98% UVA/UVB
XPEL Window Protection Film also block 98% UVA UVB and is clear as glass. Went on the outside. They also gave me a free EXPEL Prime+ 70% on the inside for free. But DO NOT do it through the dealer. Much cheaper 3rd party
