It may also be 'buyer beware'
Colleagues at GPS Warehouse tell me ....
The SPIII when first introduced had a 32Mb datacard plus one unlock code for the software, so you paid out more for full unlock to get additional countries.
Later, it became SPIII deluxe with a 128MB datacard and full unlock access to European maps with 'City Navigator' V5.
I suggest you also check as to which version of 'City Navigator' software it has also.
