I need to learn about Sirius sat. radio. for NASCAR?

If the dump truck has an FM radio it will play through it without hooking anything up (to the radio or truck). Throw the antenna on the dash, plug into the cig. lighter, tune the radio and you're rockin'. If not they sell a boombox that the radio docks onto to make it portable. You can also get the stiletto which is like a mp3 player with earpieces.
