LOL, my front patch died. When I got it back under warranty, I never put it up. I have the R3 running radar from the front and the rear patch (x,k band off). I do need to get it up so I can compare the 2. That's another thing with these high end systems. Several years from now, this stuff is sitting out in cold/hot/weather, it's going to quit working. Out of warranty, I'm not dropping $1500 on a replacement patch or $400 on a screen. It's just not happening.
