can someone please point me in the right direction? I have a tomtom xl 340 s and I am trying to update the maps on it using this guide TUTORIAL: Clean Install - How to install the latest map and navcore from scratch! but I don't know how to check the navcore and compatibility for the newest US maps and also, when I try to download the maps it takes me to ilivid? Help will be greatly appreciated... I come from the cell phone world and this GPS stuff is all new to me.
