Yes, the radio needes to be removed and the bottom plate removed. Then, use a contact cleaner from radio shack to clean the knob pot. The knob pot is a hole in the piece that the knob shaft connects into. You may have to look around the piece to find the hole into which the cleaner goes. Don't be afraid to use lots of the stuff, it works. Do, however, be careful to limit the exposure to the rest of the radio. If the radio won't reset after installion, leave the key on for at least 24 hours and the code will then be accepted.

Good Luck,
