i have the 6disc changer with nav sat and ves radio system. when i got in to listen to the cds its saying i dont have any in the unit and when i try to load or unload it it wont do nothing. i no it is full i think it might be in between say disk 1 and2. is there any way to reset it or something. when i push the load button it tells me to select one of the six presets but when i do it wont do nothing. the 1-6 preset buttons work when im in radio mode so i dont think its the buttons. and to top it all off everything worked last night. the wife took it today and said it worked
