Thanks, Wojpen.
For the prompt reply.
1. I copied gfx and ui_android folder into root of iGO.
2. Theme was installed and I selected defualt NextGen Day and Night theme.

After this, I noticed following 2 issues:
1. My car cursor is not being displayed.
2. Sometimes, problem with GPS signal, it is unable to catch signal. It was not happening earlier.

Any suggestion please?
Do I need to delete "save" folder and restart again?

Thanks in advance.
