Keep in mind that "clear view of the sky" doesn't literally mean line of sight to the sky. The main thing is to make sure it is not directly blocked by metal. I have two (one Autometer unit, one Classic Dash branded) of them mounted under the dash pads on different cars, and both work great. One is in the opening where the factory AM radio speaker would go, right under the perforations in the pad. The other is in a spot where there was a factory void in the metal top of the dash, just under the pad and right above the glove box.
