I can understand why they might be expensive (at least compared to the current option), but I don't understand why they might interfere with the other things listed. For example, this cited website about Electrical and Magnetic Fields says that power lines don't have enough power to significantly affect GPS units, and a single electrical resistance line isn't carrying nearly the same amount of electricity as power lines. This pdf also backs up that claim. I don't know a ton about the subject, but it seems that at least for GPS, that interference would be so marginal that it can be discounted.IMBoring25 wrote:Heated windshield is not a new idea. It was offered as an option on my sedan that's about to turn 26. Mine is not so equipped. It was expensive and it plays havoc with GPS units, anything pertaining to radar, and turnpike pass readers.
It might not be an EMF issue, it might be a conductance issue. Perhaps the glass doesn't allow the signal to pass because of a layer that doesn't transmit it well. GPS is as much about line-of-sight to the satellites as it is about traditional EMF noise interference...sure, the signals can pass through metal or concrete sometimes, but sometimes not so much and sometimes something that passes visible light may not pass GPS signal so well.Squint wrote:I can understand why they might be expensive (at least compared to the current option), but I don't understand why they might interfere with the other things listed.

But those signals all pass through our current windshields. I was just talking about a border line near the outside (perhaps an inch or so from the edge of the glass - that would probably be close enough to work for wipers on most cars, too) of the front windshield - not a whole windshield with electrical resistance heating lines.theholycow wrote:It might not be an EMF issue, it might be a conductance issue.

For whoever understand this stuff better than me, here's the info about the frequencies used:

Plus there are enough hail damaged cars up here I'm sure.
