I just finished installing my Tuner and it works great. The only thing I would like to see is some type of tab with a hole in it to make it easier to secure with zip ties. The signal strength meter works great and helped me trouble shoot a loose attenna ground. I also get a faint blue line when I hold down the menu button. I figured this was just to indicate that the player is in "enter preset" mode. I'm very happy with it.
