Hi I am in the process of updating an old Go750 live. So I copied everything onto my pc. Used downunders auto nav core installer (thanks brilliant just a shame I have to un pack it each time I want to use it. unless i am doing something wrong). Anyway I just thought as my map is downloading (glad i just got a filefactory premium account:)), what files are needed from my backup for live services?

easiest way is to overwrite your existing setup, the live services are bound to your account but a few files on device contain additional infos.
I don't have a live TT so I never had a chance to compare between the systems.
But it should be enough to simply patch your current Navcore and add the maps you need.
