What the OP is trying to say is that the Road Trip works "in motion". The problem is sitting still the mechanism will not "sleep" on the signal. He has to immediately power down when it finds a signal otherwise it winds up and does a restart over and over.
I recognized these symptoms. I know it seems backwards but I can enjoy satellite when parked only when I switch off the 12 VDC supply as soon as it gets a signal. Driving down the road my wife can enjoy Criminal Minds with only the normal interruptions.
