I have the thermally/acoustically insulated glass option. I just finished a 1400 mile trip and I have a few observations that folks might be interested in...
1. Toll Transponders: I mounted an IPASS transponder (EZPass compatible) in one of the designated areas on my windshield (the little "checkered" areas near the rear view mirror). Initial testing indicated it should work. I tested 2 gated toll booth and 2 "over-the road" tolling stations with no problem. However, on my trip, I had some issues with some toll booths NOT finding the transponder. I paid a few tolls by hand but then took down the windshield mounted transponder and replaced it with a front plate transponder. (I had the plate transponder in the car with me - wrapped in tinfoil - just in case I had issues). The front plate transponder worked every time. Folks might want to keep this in mind. It appears that mounting a transponder on the windshield might not be as reliable as you might think. (Even if mounted in the designated area).
2. Radar Detector: I also noted that my radar detector (Valentine 1 Gen 2) was not getting warnings from the front. I would side and rear warnings but never front warnings. I also mounted it as close as possible to the designated area to the right of the mirror. However, I couldn't get it close enough to the roof line or the mirror to get a perfect view straight through the hatched area. I'm currently in the process of designing a 3D printed mount for the V1 which should allow me to position the unit higher and closer to the mirror to resolve this issue. However, if you are mounting an internal radar detector on your windshield, and you have the insulated glass option, you may want to be aware of the challenge...
