How to edit/update POI entries in iGo primo WinCE

Hello,

Is there a way that I can update and/or edit my POI databases in iGo primo 9.6.5.221194 on a WinCE based head unit (S-100)?
I dont want to sit in the car and waste gas or eat up by battery. Is there a way I can do this off-line (on my computer)?

Thanks for any help.
