On my recent road trip, I noticed a handy feature on the map. The lightning bolt in the upper right hand corner lists the Superchargers.
This pulldown menu also shows you any visited chargers, which likely includes your home. A little red symbol will appear on your map. Unlike other locations, you can touch on the red charger point and navigate to it.
I found this feature quite useful as it is a quick way to navigate to these locations. Both the superchargers and the public chargers are not obvious to spot. Although they are signed, they are quite small and the navigation can be helpful finding them the first few times.
From the map, I can see my car was charged at two locations at the Fremont factory. For the record, there is no public charging available at Fremont. Perhaps in a pinch, the service department can help you charge up your car.
