radio code for 91 sl500

Hey, my radio went to "code" after the battery went dead this winter, does anyone know if there is a procedure to retrieve the id # so i can get the radio code (other than removing the radio)? thanks

Try asking your dealer; with your VIN and proof of ownership, most dealers will give you the code free (if they can get it). If you're already shown in the dealer's records as the owner (most of us are), all they need is the VIN.

Alternatively, if your unit is a Becker, try this form: http://www.beckerautosound.com/Code_...est%20Form.htm

If the radio is original to the car, all the dealer usually needs is the VIN. If it has been replaced, the serial number of the radio is needed.
