Nokia Navigator. Please Help!

Have a Nokia navigator GPS, pretty good but with too old R66 soft and maps.
Nokia doesn't really have any support for it. Even my computer doesn't recognise it. All I can see is the sd card.

I wanted to use one of the Igo softs on it. I saw the post about the 2din, think it is the same installation, but have one little problem, I can't access the .exe files or any kind of sys folder. Tried to use the totalcommadCE, but Microsoft Mobile device doesn't connect with my device. How can I get things moving?

Ps: It has Win CE 5.0.

To get to the desktop of winCe, just tap about 20 times on top of the written word "about" , in the menu, setup of your Nokia device. On WinCe desktop you can find the sdcard on windows explorer and run another .exe file. Complicated but works...
