That is common on most Chinese headunits. Just go to settings, gps path and point to Primo.exe, iGO8 .exe, Navigator.exe etc etc.
If it doesnt work just go back to the original path but it should be ok .

Use this as the path if you want and add your navi programs to it. (Menu.exe)

GPS Menu.
[Only registered and activated users can see links. ]

I dont remember where I got it but it is a good add on.
Open Config/gps.ini to set up the programs to point to.
Check what it loks like in SystemInformation32.exe.
