Hi I just saw this and I am thinking I might be the other forum member you mentioned? I had the whistling noise and did tape my windshield to try and isolate it. Long story short, the dealer ended up trimming the gasket around the windshield and after that I’m happy to say the whistling was gone and has not returned. I hope this helps.I have the whistle noise coming from my hard top (only generates at 45mph or higher) and after reading this thread for months I've tried every adjustment recommended. Based on its central location (essentially the gap where the freedom panels meet) I was convinced it had to be the position of the panels - I tried to make sure they were perfectly aligned assuming turbulence may be causing the noise. I experimented with clamping them down more, then less... all to no avail. Was ready to write it off as cross wind and nothing more I could do. Then today after a wash I decided to tape the entire rubber gasket around the windshield went for a drive and bingo no more noise! On the way back I removed the tape and whistle returned. I recall another forum member taping his windshield but can't remember the outcome. Off to the dealership this week to see if I can get it resolved.
