Hi thank you for your question hope this helps.
There two places the factory may have put the radio code.
The first is in the owners manual on a little card. you are looking for a 4 digit number
Next place on top or of the fuse box under the hood (next to the battery). if its not on top, check inside the box. its a 4-digit code.
If you find nothing in either place the dealer will need to pull the code using the radios serial number.
The bad part about this is the serial number is XXXXX the radio.
The dealer will charge you 25 to 50 bucks to get the serial#.
Or you can get the serial # XXXXX and tack it to a dealer and ask for your radios code
this should be free.
Hear is an easy way to get the serial#
All you do is, slide your hands into the space right below the player and pull out. Do it carefully though. The panel will slide right out and you will see the serial# XXXXX top of the player.
Tack this number and the registration to your local dealer and tell them you need the radio code.
They will also give you the instructions to input the code this should be free
Hope this helps
