How to copy the new Map and make it active

Hi,
I've got iGo on my car android dashboard. I check the map installed and it seems to be very old, I search the fourms and I found a new version, ad it has the following files:
Egypt_HERE_2015.Q4_160219.fbl
Egypt_HERE_2015.Q4_160219_(AP).fpa
Egypt_HERE_2015.Q4_160219_(JV).fjv
Egypt_HERE_2015.Q4_160219_(JW).fjw
Egypt_HERE_2015.Q4_160219_(SP).fsp
Egypt_HERE_2015.Q4_160324.poi

So what is next? do I just need to copy the new files to "iGO/content/xxx" directories?
How the device/iGO will know to use the new files instead of the old one?
Do I have to reset or set any options?

Thanks in Advance
Mr. H
