switch panel for what? does it have an antenna on it, or is it supposed to? alot of devices that have internal antennas are using patch antennas, which are basically just laid out on a circuit board - and most suck. could be that you have something interfering with it, like an fm modulator for an external sound source (disc changer, satellite radio, etc.) - or worse yet a cell phone jammer, which is really just a wideband transmitter putting out noise across a wide spectrum. i've heard of some jagoffs using those on the road, although i don't know anyone personally that interferes with wireless networks regulated by the federal government. one reason it may work better when put up against the headliner is the reflection from the steel roof back to whatever device it's supposed to connect to. that, or a lesser possibility, its being rebroadcast by the xm antenna. where's the receiver for the switch mounted? if it's behind a bunch of wires or steel then they could be acting as a shield and not letting the signal through. without some more details, i'm pretty much just pi$$in in the wind - but y'all know how much i love that . . . . .
