Well, here is an accurate representation of my sister's car stereo features:
I'm assuming anything on the market today would be an upgrade.
The features she wants is iPod connectivity and an AUX input. I could just go and buy a walmart unit with those features, but I want it to be high quality.
In your experience, what is the highest quality car stereo manufacturer?
EDIT: I'm also not upgrading my sisters car speakers, so it's going to sound roughly the same anyways. I'm just giving her more features.
