I don't know what those things are called, but those signs that show your your speed. My V1 is about 6 or 7 years old, has never been upgraded. I stopped using it for about 3 years.
I plugged her in again and i went through almost a dozen different radar signs on a road trip and it only picked up 2 of them.
s there some sort of new radar tech out that's preventing me from picking up the signs? or is there a problem with my V1?
