okay I have to use a cassette adapter to listen to my ipod, sounds okay for my 80's music, definitely some static when pavarotti or mozart is cranked up, but at least its acceptable for a car with no ipod dock or mp3 capability. I know I can put a DICE unit into my prius, but I can at least make due with my current situation. but my poor sisters 2004 corolla has no aux input, no mp3 capability, and not even a cassette player (she's SOL), the DICE units for the corolla are the kind that hooks up to the FM antenna, not the direct connect like the DICE units for the prius, so has anyone put a different brand IPOD docking unit into a 2004 corolla??? how difficult was the install?? has it been reliable??
