I agree with Jimmy303, the picture quality is pretty good. When moving you get "picture flicker". Some channels come in real good, others are "snowy". The antenna is attached to the back window of my Silverado. Is there a better antenna out there than one from Pioneer? One that doesn't advertise you have TV in the truck.
Also, what is the DirectTV Option? I'm considering Sat TV for my 5th Wheel, but I haven't heard of anything for the truck.
