Heat-insulating glass and Radar Detector performance issues?


Recommended Posts

I overhead someone mentioning that the heat insulating glass option (14GY) impacts the performance of one's radar detector especailly if the unit is mounted on the visor. I just the had factory upgrade my Valentine Unit with the latest firmware and was going to install it in my new Cayenne as the unit has saved me on many occasions when I had it in my M6.

Has anyone had any expireience with degradation of performance as I don't want to find out the hard way on the NJ turnpike?

Thanks in advance - Steve

Steve,

I'm not sure if there is any comparison, but I use a Beltronics unit mounted on the windshield just below the rearview mirror. My Cayenne has the I4GF option, which is "Windscreen of Tinted Glass". I suspect this is not the same thing. I'll be curious to hear if anybody has any experience with your issue.

FWIW, I have never had any problems with mine.

Good luck.

Not sure about this exact option but the heat insulating windscreen on the M5 cut the infrared reception of my motorway toll e-pass (so I had to manually hold it out the window!!)

If the radar detector uses any of the same frequencies then it will very likely be affected. Surely you can ask the manufacturers, no?

I had an '01 Dinan modified 740i Sport with what they called the "IR" windscreen. The radar detector DIDN'T work behind the glass and there were cutouts at the center in the bottom and on either side of the rearview mirror where you could mount a detector or a toll transponder (presumably put there for that purpose). Not sure about the Cayenne's option - but if there's any metallic material embedded in the glass - you will get degraded performance.

On a related note, that windshield was awesome - really seemed to reduce road glare and keep the dash MUCH cooler in the Miami sun.
