How to install system, navio 4301

Can some1 tell me what I must download to get the newst maps to work in my navio 4301. I Have downloaded the new igo and i dont get it work. can some1 show me how can I do this

I do not know the navio 4301.
However, I found some pictures on the internet, showing the device having an sd slot and a screen showing iGO.
When that is correct and your device has an igo installed, can you tell what igo build? Also when connected to the PC, can you explore the device and more important the iGO directory (can be called differently).

I have downloaded the new 8.3.2.138649_Apr_19_2010_PDA nad then the latest update added new voice, map, and language. I deleted the old folder (V7) from my sdd and made a new folder igo8 and when I start my gps and then my navigation dosent start at all :/. This is how my sd originali will look like
