check out what I found, I was looking for a GPS unit called: "Nextar" and found this:
NOTICE TO STATE OF CALIFORNIA DRIVERS:
California Vehicle Code section 26708(a)
(1) provides that "No person shall drive any motor vehicle with
any object or material placed, displayed, installed, affixed, or
applied upon the windshield or side or rear windows." Drivers
in California should not use the suction mount on
their windshield or side or rear windows.
If this is true, should we not be getting tickets for our detectors?
