If you can find a spot like that, you can at least try it before exposing on the dash or hassling with running it outside. The satellite radio is another matter though. It really needs to be outside ideally on the roof. Mine is on the roof right above the third brake light. The wire goes into the third brake light housing, above the headliner, down the pillar ... well, you get the idea. If you have the fabled combination antenna (GPS and radio combined), it goes on the roof for sure.

Phil,
With the GPS antenna under the dash like that, won't the dash block out some signal thus lower strength than as if you were to mount it on the front dash?
