software compatability

[Big_Jessie]

Hi, I have just bought a Medion MDPNA from Halfords and it seems to be ok. However, I have no confidence in what i can download for it and what i cant. for example i want to dl the speed camera database, in fact i think i have, unfortunately now i have no idea how to install it, or what is compatable with the navigator gps 4.4. Also i am in Northern Ireland, so I seem to end up driving in "grey" areas some of the time. so 2 questions. 1 Are there rules or similarities between gps systems?
2 Are ther better maps i can dl for my system?
Any pointers will be greatly appreciated
