Answer
Hi Dave,

This sounds nuts, but you must turn your key to the on position and leave the driver door open for 30 minutes. This will reset the radio to accept a code. To get the code you must remove the radio and get the serial number off the back. Call Nissan and they will give you an 800 number to call and they will give you the code.
