ara178, you need wayfinder subscription for that feature on the map app that comes with the device. You can bring up the menu for it by clicking the right hand side of the map. I tried to use the trial but I got some weird error.

The home city thing is anyoing. I live close to Albany NY, and that wasn't even on the list. It seems only certain select major cities are on the list. But at least they cover all the time zones, which I think is the base idea of that thing.
