Hi, sorry but we do not have any solution for this device because it is running WinCE.NET OS. You shouldcontact theseller and return the product for a refund.
Most of our GPS software only work on Windows Mobile 2003 / WM5 or WM6 PDA / Smartphone.
FYI: These PNA devices are called OEM (Original Equipment Manufacturer) devices, because these devices are sold with embedded software.
Due to industry practices, the support for OEM devices is provided by the manufacturer of the product.
As you bought an OEM device please get in touch with the distributor regarding the maps/updates/support.
