In Motion Domed Sat. Ant.

We have out since 06. It is not high def. It works well but noisy when searching. I turn the switch off once it locates sat, when we are parked. Otherwise it tends to hunt a bit in each direction for some reason. Doesn't lose the signal however.
It is worthless going down the road. There is an ignition interlock that cuts it out so you can't watch tv going down the road. Probably could in the bedroom. We haven't tried.
