Simple and works well.
Crutchfield Customer Review (What's this?)
Bravo to Alpine for building in some extra functionality to their systems. It's great that I can just switch source to "AUX" and anything I choose to play through the RCA adapters will come through loud and clear. <BR><BR>Setup was very easy and works as advertised. Basically you just set the unit to switch to "AUX" mode (it becomes another choice as you toggle between tuner and CD modes) and plug in the adapter. Sound quality is as good or better than anything because it's just a direct line-in. I like it a lot better than the FM modulator in my other vehicle, but that's another review...
