Wiring for XM radio in a Century

Hi all,
I drive for the pumpkin and Im trying to figure out a better way to wire up the XM. I went today to try to figure things out a bit and Now the wires are just on the floor in a heap, lol.
What Im trying to do is just hide the wiring and work it around so its not visible...or less visible than it is now.
I have the Century for a tractor.
Right now, the set up I have is the xm is velcroed (well it will be as soon as I get some 'aint gonna get this sucker off' strength velcro) to the dash above the various switches. Was thinking about putting it low on the windshield but I've heard some states have laws against that. I'd just like to get it closer to my driving field of vision.
From there, I have three wires sort of going all over, The power going down to the cigarette adapter by my knee, the cassette adapater (the FM method doesnt work at all with this radio...not sure why), and then the antenna cable.
The antenna cable then goes up to the overhead CB radio mount cubby where it then joins the other antenna cable (not sure why there is two). They hook up and form a jumbled mess of 24343 feet of cable. I then have it looped over on the inside as its open, to the overhead junk compartment which is in front of, and above my head. There it then comes out of that compartment, slides through the air horn pull, out the triangle mirror and is wrapped around a couple of times onto the left mirror mount by the CB antenna.
I tried having the antenna in the truck but I couldnt get any decent reception, and with the set up I have now...I only lose signal for a few seconds a day....once going west and three times going east.

Now, I know lots of other drivers have theirs set up very cleanly which is what Im looking for.
Any ideas, suggestions?
Thanks,
Ryan

 

I was thinking about getting a different radio for the truck but I wasn't sure how the current one is wired up and can be taken out. I figure its just a simple plug. The one I have works OK, outside of the fact that the sleeper speakers fade in and out with the bumps on the road and if I play with the volume knob, they come back on for a moment or so.

Now how did you guys get the antenna wire to the outside without the wire being in the way? Right now, mine goes through that triangle window, but its in the way of the front curtains if I want to close them and I havent figurered out a good way to hide them (or at least minimize them visually) and still get them outside.
