Radio Problem With 2000

DOE S ANYBODY HAVE THIS PROBLEM? MY RADIO CUTS OFF AND GOES INTO THE CD MODE WITHOUT ANY WARNING. IF I PUSH THE EJECT BUTTON IT GOES BACK TO THE RADIO MODE. THIS IS A REAL PAIN WITH THE XM SET-UP. IS THERE SOMETHING I CAN SPRAY INTO THE CD OPENING OR IS IT A SOLDERING PROBLEM.
IT IS A FACTORY STOCK AM/FM CD.:shakehead :uhoh:
THANKS FOR ANY HELP.
