I'd go for a Parrot Bluetooth kit. Charges your Ipod/Iphone, gives you a display of what's playing or phoning. You can also use a USB stick and it gives you a line in.
The kit uses its own amp but your car's existing speakers. Very easy and neat to fit. I have fixed the display on the top of the steering column.
You don't need an 'aux stereo'.
