I know the Fastrak issue has come up time and time again, but I can't seem to find any consistent information about mounting a CA Fastrak transponder in a 2017-18 Model S with All Glass roof. I have held up my transponder while driving under the sensors in all the suggested areas (right of rear view mirror or in the back on the parcel shelf) in various orientations (upside down, 90 degrees). No success.
Here's my situation: I drive I-680 between Walnut Creek and San Jose everyday. The new Walnut Creek sensors never make my transponder beep. But the Sunol sensors through Fremont seem to make my transponder beep just fine. I even went as far as getting a new transponder (candy bar shaped one) with the same results.
When I've called Fastrak customer service, I get the runaround...the last person I talked to told me that "some sensors make the transponder beep and some don't" which obviously in my case is a load of crap because I keep getting charged for the Walnut Creek 680 lanes and not the Sunol lanes.
If any Bay Area people can chime in with your experiences, I sure would appreciate it. Thank you!
