i got an alpine am/fm/cd/satellite radio installed in my aveo over the weekend. my friend steve had the same year 04 sedan as i do and his car was broadsided by a cadillac. he gave me the whole set up prewired for his car. all i had to do was take out my radio, and plug his in and now i got awesome tunes!! i called sirius and gave them the esm number and got sirius. the swap took 30 minutes. i ran the wire for the sat antenna and i was done. i know he paid like $400.00 for radio and install. the reason he gave it to me for free was that he felt the insurance company paid him for it in the wrecked aveo. he bought a mazdaspeed 3.
