If unlocking your maps to this computer for the first time:
Connect your GPS device to your computer's USB port and click the 'Find Devices' button below. When your device is detected, enter the serial number found on your GPS device and the 8-characters product key found on the back of the disc's case (for TOPO maps the product key can be found either on the manual or pasted inside the case on the left side). Then click the 'Unlock Map' button below.
If you have already unlocked your maps and would like to retrieve your existing unlock code(s):
Connect your GPS device to your computer's USB port and click the 'Find Devices' button below. When your device is detected, enter the serial number found on your GPS device and click the 'Retrieve Unlocks' button below.
