I think I got it fatboy, i dont need tts so apart from that i think i placed everything else on the latest 2013 nz maps I found in this forum. seems to be running smooth now, although part of me prefers the lite igo8 on my icn 520. but not bad. larger screen, and newer map and software should do enough for me. thanks a lot for the help.
ps: are there any additional softwares you would reccomend me to have in the navman, I got a picture viewer, media player, office, notepad, igo + smart st software, I dont know. Plenty of room left.
