I recently bought a LCD 2 Din radio on ebay but the software for the GPS wasn't included. I need to know where can I get it and what do I need to get my gps running. My radio has a GPS SD card slot.

Here is the link for the radio:
T767G Car DVD Player with GPS, Bluetooth, Ipod, SWC,800x480pi HD for SUZUKI SX4 - Tradesolution HK Ltd.

Any help will be appreciated.
