Has anyone had trouble w/ their cd players? I just got the regular one but every once and a while it'll say error and will only play the radio. Then I can't get my cd out. I read in the owners manual that it would have the tendency to malfunction in the heat, but at night time here in Houston its bouncing back and forth from 65 to 40 degrees. And even in the day time it mostly only reaches about 75! I was just gonna get a after market h/u but I don't know if the same thing will happen. It happens about once a month and is more a annoyance than anything else. But does anyone know if its a defect w/ just the radio, or is it something else.
