Honda CRV 2000 Radio?
 

I have the 5 digit code. Radio says code...I try to punch in the code and nothing happens. Do I need to do something PRIOR to punching in the numbers (i.e., holding another button down?). Yes, the radio is turned on :)...and no, I have no manual...Any help would be appreciated.

Just bring it to a Honda dealership. They should be able to either do it for you or give you the 2000 CRV manual so that you can figure it out yourself.
