Windshield mounted gate pass issues

suspect a “film” or material within glass inhibiting signal transmissions. Has any one found a work around or soloution?
I am trying various positions on windshield as suggested by info available.. but still baffled. THANKS




Good luck.

success in the location high and right of rear view mirror assembly!....yeah... gate pass now operational..
Still aesthetically acceptable, and mostly out of vision...
Small but important detail in auto daily use....information seemed somewhat obscure in manuals etc...
Thanks for the guidance to Soloution.....Otherwise GLE450 appears a great choice for us!
