I just posted a solution for this problem. It comes straight from the radio manual. The dealer should have told you this. If you want him to do it he'll charge money for his time. IF YOU LOST YOUR CODE. THE DEALER CAN HELP YOU OR IF YOU HAVE YOUR 4 DIGIT CODE:

Owners manual says leave it turned on for an hour and you'll be able to try entering the code 3 more times. get the SN off of the radio and call honda with your name, your VIN, and the radio sn.

try another dealer. maybe try to get ahold of one of the techs at lunch time. this info should be free to the car owner, just be ready to supply the title to the car for some proof. maybe try buying the parts guys lunch or coffee and donuts....this usually works for this type of problem. unfortunaley this info really is dealer only..

Not all fords need radio codes
Codes where used from 1998 on,so I was told last week,when I called a dealer, to ask that question,in order to help someone.
If your vehicle needs a code ,you have to pay, to put the scanner on it,to retrieve the code
You can go to a non dealer repair shop.
