Hi. I have a 2005 Hyundai Coupe SE. It has a simple radio, and supposedly a 6 CD changer. However, no matter what I have tried, I cant input more than one cd. The changer is not in the boot, and tried various combos of buttons and cd selection. The radio also seems to have set to certain volume etc when I start it up. And for EQs, it was allowing me to adjust all the settings, but now it will only let me into Fader and Balance. Please help!! Im so lost!!
