I have traffic guard enabled on my V1, which I purchased late in December. Living in NE Ohio, it's a must. Lately, I've noticed that it alerts to the traffic drones even though the guard/filter is turned on. It only does this in a couple of areas on Interstate 71. I'm starting to wonder if the drones have fallen out of tune and now the V1 doesn't recognize them as falling under the traffic guard/filter? Is that possible? If not, I am concerned there may be something wrong with the unit itself.
