Nissan 350z Radio Locked
 

Hello everyone! I'm new to this forum and I'm facing a problem. I changed the battery in my 350z and now the radio is asking me for a 4 digit unlock code. I called the dealership and they asked for 220 RON for the unlock (about 44$). I did a google search and this site came up : nissan What do you recommend me to do? Has anyone else experienced this? Thanks in advance!
