asking for help from Greece!having mapfactor application with bought tomtom maps : some questions :

i am Anastasios Mimikakos (or my nickname "tassos photography")  , 

i have since some months "mapfactor " application and at the same time bought  the tomtom maps .. 

I Have some questions : 

1. i have bought my country's map (Greece) if i buy "Europe's" map does it improve sth inside my country or its only for those who travel abroad ? 

2. the application mapfactor , has lots of settings and advanced settings , is there any ebook explaining each setting even if it isnt for begginers in Greek  !! ? , if not .. at least in English 

3. is there any PAID version of the application ? ie to upgrade it to even better ? , or its remains same .. free application and paid maps ? 

4. if i find mistakes in maps , in which site or email should i attend ? to mapfactor's or tomtom's ? 

thanx for your space !! 

waiting your answer(s) here or in my email tassos.photography@gmail.com
