I want to update the maps, but I don't know how.
It has a memory card in that carries the maps, so I don't know how I could update that on my home computer.
Also, ho can I tell if the respective maps I use have been updated. I live in a new estate and I want to know that that estate's maps are visible before I would purchase an update.

unlock the iCN520 and install other GPS software on it. The iCN520 can run virtually all the major GPS software available today; from Tomtom to Miomap and beyond.
Instructions on
how to unlock the iCN520 can be found at:

jkirley I have an iCN and I live in a brand new suburb on the outskirts of town. I cannot get any recognisable GPS until I travel to the neighbouring suburb. I would like to upgrade my maps, so I no longer have this problem

edjo1932 I have a ICN 520 Navman since 2005 and I wanted to upgrade the program of the memory to have the new roads installed.
