I had all windows tinted except the front windshield..but now that it is getting hot (we had 3 days this week with 95-100F), I think I must have the front windscreen tinted! It is unbearable!

I did the front windows at 35%, all other windows with 20%. Even though I have the privacy glass option, I still tinted all the windows, since the dark BMW glass does not offer any real heat prevention.

I had 3M Ceramic film installed. Paid $220, 5 months ago. NO radio problems. Looks and performs great. I would not own a car without tinted windows, especially where I live.
