IS MY WINDSHIELD BAD FOR DETECTOR RANGE?
|
| |
 |
I have a 2000 Lexus LS400. Do I have one of those
windshields that impair radar or laser warning?

Sorry, but we haven’t been able to test the windshields
of every car for every model year. Here’s what to watch
out for; any glass with a metallic film, usually put
there either as a heating element for defrosting, or as
a solar barrier to reduce interior heat from the sun.
You can usually tell by looking carefully which
windshields have the film—if you see an unusual bronze
or reddish tint, check with your dealer.
Be especially watchful of GM front-drive minivans
(1989 to present), older Ford Taurus, Mercury Sable
and Lincoln models with the optional InstaClear
windshield, and the "insulated glass" option on Audi
A8 models. This insulated glass is more common in
Europe; BMW-3-Series models sold in Europe have it,
for example.
One other point; if the tint band at the top of your
windshield looks a lot darker than others you see in
the parking lot, I suggest you avoid placing V1 behind
it if you’re driving in laser territory. Most
windshield tint bands are okay but why take a chance.
For more information.

My rear window has lines through it for defrosting. Does
that hurt V1’s rear reception?

When V1 is mounted on or near the windshield, don’t worry
about defroster lines, or the fine antenna wires you see
on the rear window of some cars. Radar and laser zip right
past these distant obstructions.
Be careful of wires in the windshield though, because they’re
close to V1. Usually the horizontal wires are no problem,
but I recommend that you stay a few inches away from vertical
wires.
The plastic rear windows on convertibles are transparent
for radar, even when the plastic gets old and foggy. But
the harder it is for you to see behind, the harder it will
also be for rear laser to get through. Because rear laser
warnings are rarely helpful however, I wouldn’t lose much
sleep over the loss.
