Re:Wrong type of "compatibility" (Score 1)

Newer versions of cars add satellite radio, GPS, and MP3 capability, but I don't see any car companies provided these features on older models. The car companies aren't, but the aftermarket provides an abundance of options for most cars. To extend the analogy...a Sony car CD player will plug into most cars, and it operates the same way regardless of which car it is installed in. Sounds kinda like what Firefox (or Mozilla, Opera, etc.) is for web browsers....
