I just made a trip from Wisconsin to Portland,OR (and back) in a 6.3 a few weeks ago using a V-1 on the open road for the first time. It works! It's nice to know which direction the radar signal is comming from. One encounter with a radar jammer took me a while to figure out...
These things are worth every cent they get for them. Get the remote display, I'm glad I did. Otherwise you'd attract "sheep" because of the large display on the unit.
