I have the same problem, but I found the unlock code on my Smartphone. In the Inventory of the cartridge you can find it. You have to type this under option 2.

Copy the zip file to folder on your PDA and run PlayerInstall on your PDA. Than you have the program available, but I was not able to get it running. It does not get a proper GPS connection.
