here is the situation :
i have 2 rd in my car : sensoro hard wired + v-1 version 1.7 built 2002.
The 2 rd are always on one at a time , never together.
Going , NY state , 87 .
The v-1 is on , sensoro is off.
I pick-up an alert from trooper coming in my back ,
he is at least 1/2 mile behind.Full alert .
I shut off the v-1 , turn on my sensoro : no alarm at all , nothing.
Did the same at another time , same scenario .
My v-1 is dashed mounted , lighter plugged.
The Sensoro is hard-wired but mounted at level knee , it always
work well but do not pick-up this kind of radar :
mobile radar that catch speeder from the back , used in NY highways.
Any clue of what is the explanation.
