SOURCE: Hi, I bought a 2007 Honda Ridgeline The radio

you can call honda if it is the factory radio.. if you give them the vin number they should be able to help you... once you receive it you should keep it saved somewhere because every time you disconnect the battery it will reset again... sometimes you can find the code in the owners manual or sometimes you get a little card with the code on it... good luck
