The dealer in Jacksonville, FL. Explained for FREE, that the code is on the back of the unit. Pull unit out with DIN plug puller ( get it at Parts store or hanger can be used ) 4 digit code entered it works!!! If code entered is accidently entered wrong, you must clear code by pressing and holding BAND until 'CODE IN' appears in display. That was my problem. The ex-owner put in wrong code and even when i put in correct code, it did nothing. You have to clear the mistake and wait until it tells you to enter the code. Finally MUSIC !! Hope this helps someone!!!!
