What is vg2 on a radar detector?

VG2 (Vehicle Generated 2) is a technology used in some radar detectors that allows law enforcement to detect the presence of the radar detector itself. When a radar detector equipped with VG2 is turned on, it emits a signal that can be picked up by VG2 detectors used by police officers.

In some states and countries, it is illegal to use radar detectors equipped with VG2 technology, as they can be detected by law enforcement, leading to potential fines or penalties. As a result, many radar detector manufacturers have stopped including VG2 technology in their devices.

It is important for users to be aware of the laws and regulations regarding the use of radar detectors in their area, as well as the presence of VG2 technology in their device.
