Does having it mounted on the sunroof work on the non-express lanes where you still have to wait for the gate to open. Those cameras/readers are not above the car in this case and not sure how it would pick it up with the transponder being on the sunroof.
Yes it works.
Probably because this is a radio frequency ID, so it doesn't require line of sight, just lack of interference.
Something about the windshield interferes, but the sunroof and surrounding roof does not.
At least we've not had a single problem in the months since we moved it there.
We have the transponder on the drivers side where there appears to be a clear opening, but still dose t work most of the time for tolls with the gates that need to be activated. (We have tried the passenger side as well)
I drive with my head out the sunroof now so I don't have to look though all the wires and filmy mess stuck on the windshield.
In the more than 14 months I've owned my Defender and the nearly two years we've had the iPace, it only recently got cold enough to automatically engage the heated windshield, or maybe I've only just noticed how it creates a shimmer effect when it is on. I find frosted-over windshields less distracting! No wonder these things cost so much to replace!
Mount EZ Pass Flex in your windshield dotted area (if you model has it), the dots highlight the non-heated portion of the windshield. I had problems with mine that finally found the sweet spt.
I've mounted my ez-pass just like John Natsis did and have had mixed results. There are several tolls in the Richmond VA area that simply cannot register my pass. When passing through those tolls, I've taken to holding the pass outside the window. Note, if trying this, you need to get the pass out there before entering the lane. Once up next to the gate, you've passed the reader. I've spoken to the ez-pass folks and they insist that though a set of gates consistently fail to read while other gates consistently work is no indication that there's anything wrong with those Richmond tolls. Their solution is to get a license plate mounted transponder. When pointed out that would prevent me from getting free access to the HOV toll lanes, they basically said it was a personal problem, not theirs. Oh well - I just end up paying toll-by-plate wherever the transponder can't be read.
