I have XM, but I think this thread is more about installation.
I did mine by myself, which means it's the non-technical audiophite way!
I have mine plugged in through the AUX input, and the sound is great. Not perfect, but not all chopped up like the FM modulation way.
As for location, I simply took a clip that came with the kit, hooked it on the back and clipped the unit onto the vent just above the 4X4 switch.
For power, I plugged it into the pass. side outlet, so that it shuts off when the truck does.
I stuck the antenna up in the corner of the dash, and ran the wires down under the glove box-can hardly tell. Reception wise-it does terrific, unless I get within 5 feet or so of a building.
All wires are tucked an hidden as well as can be expected. As for access, it's right in front of me, literally, so it's easy to change stations. Maybe at some point when I'm confortable putting holes in the truck, I'll make it more permanent looking, who know's.
