I puchased a 2004 honda civic and needed to replace the battery. I do not have the book for the car and I need a code for the radio and need to know how to reset the raidio after I get the code.

Sometimes the dealership can research the code needed by the VIN. Other times the dealer will need the serial number that is on the back of the radio. It is a stock radio... right?

It should be in the owners manual
