My Monitor ( 7 months old) Voyger starts to fade out and jump around a little sometimes during our outings. It fades out to where sometimes I can barely see my toad. Then I can sometimes loose the picture. I turn it off for awhile and when I turn it back on it works for a undetermend time. I just had the monitor and camera tested and they could not get them to act up. I get a little interference when I turn on the AC. DC voltage is 14.7 ac off and 14.3 ac on. Could it be a problem with the ground wire? I need some ideas leaving in 10 days for 3 month trip out West. Sure would like it to work correctly.
