Urgh... Aftermarket car stereos are an abomination. My car doesn't have an AUX in and I wanted to hook up my iPhone so I thought about replacing the standard Ford stereo for an aftermarket one. I must have looked at a hundred different stereos and every single one of them was uglier than sin. It's almost like they are being deliberately designed to put as many flashing lights, buttons and knobs on as physically possible.
My Ford stereo is a double height one - it has a simple LCD display, an ON/OFF knob which doubles as a volume control, 6 Radio Presets, a Forward/Back rocker switch and a menu button. That's ALL a car stereo needs.
