I want to unlock my sony dvd recorder model number, RDR GXD 360. Can you help?

Unfortunately there is no unlock code for your particular unit yet. Someone has to hack into the BIOS of the machine and then figure out the Service Unlock code. To date no one has taken the time to do so. You can try a search on the web to see if there are any retailers selling hacked versions. There are sites that will actually replace the BIOS chip with a special one of their own. Of course this will entail your buying a machine that you already have. You can keep checking back with us to find out if a code becomes available.
