Alright, I finally finished my XM Radio installation. The reason I went with XM was that it cost me $35 for all the up-front parts. I installed it on my dodge neon such that the cord ran straight out to the driver side, then down the black rubber groove in the roof.
Antenna attached to roof, cord secured with electrical tape and some krazy glue:

Antenna cord secured to black groove in roof by tape and glue:

Cord running alongside windshield insulation. Attached with krazy glue:

Cord going into door hinge, bundled up in a nook:

SkyFi2 Attached to the top of the dashboard. The antenna cord is pushed into a groove, and I am workng on hiding the other wires:

My cutom mount using bent-back 32-cent L-Brackets from hardware store. They are secured to the radio and the dash by some heavy-duty mounting foam:

If anyone is wondering, the receiver doesn't block my view at all. It is just slightly below what I see of the windshield from where I sit. It turned out to be much better than either of the provided mounting options with the car kit. My favorite channel is Squizz!
