Actually, You are picking up signals from cellular-like repeater towers. And those towers are picking up the satellite signals.

Still very cool.

XM and Sirius are very nice products, I wish there was a way to select what songs you wanted to hear, though.

I think I might opt to get a hard drive player for my VX at some point in the future (the list keeps growing, and faster than the funds)

Yes, usually the modulator plugs in to the antenna jack on the radio itself, and the FM antenna cable plugs into the other end of the modulator. So you will have to get behind the dash.

Good luck with your installation!

Enjoy!
