if you already have igo8.3 then you only need the primo software and use your existing maps and POI from igo8.3 or amigo maps which are all the same format as primo. Yes you will need the correct Data.zip for your res as the original is only for 480x272 but there are modified ones out there for others etc. I'm running it well on 480x272 nav and 800x480 on windows mobile. Works great.
