unlock codes are specific to a device ID. And you can have different unlock codes for any specific device ID. If you have a garmin system. You can run mapsource and it will tell you the device code. This device ID is stored in the SW.UNL text file on the card if you are using a card. But the device ID isn't stored as an 8 digit code. Not sure where it is stored if in a stand alone device. I can check tonight when I get home as I have a stand alone device. Also if you have a stand alone device you might have your unlock code already stored on the device. You can use mapsourse to tell you this also. Your problem might be just how you are trying to unlock your map. If you have a standalone device, it is prob stored on the device. And if so, when you unlock, you just tell mapsourse to get the code from the device. I hope this all makes sense.
