Hi, Sorry for the intrusion but i am at a loss where to begin, I have been through countless threads and cannot find what i am looking for, I currently have a TomTom Go 520 and I am in need of updated Map, If you could point me in the right direction i would be extremely grateful, I am new to this so if you have instructions on how to download and install maps i would be very grateful.thank you in advance.

You'll find the latest map here [color="red"]All new maps 875[/color].
Follow the instruction in the thread and if you are new to all this try a map with automatic installer.
Official Navcore for your TT is the 8.351 which supports all important map features.
If the Navcore is still genuine you will have to patch it using FastActivate, link is in the map thread, instructions on the download site.
