Setting the radio (the code)

If you the battery was disconnected then you need to get the code of the radio usually found in your car manual when you bought it. If you cant find the code. go to a Honda dealer to get the serial no# at the back of the radio and they should give you code to turn on the radio. Or do you mean how to set the stations? If thats the case just tune in the station you want and hold the number you want the station to be on for about 4 secs.
