My 2013 Model S is one without Navigation. The few times I've taken trips where supercharging was required, I always planned ahead and knew exactly where to go. Recently, I started a new job that will require some driving, and some of those distances will require stops at superchargers. I wanted to know the general consensus for the most accurate trip planners that can either be used from a mobile browser, or as an app for the iPhone. My biggest concern is that the trip planner accurately account for things like elevation changes, and maybe even weather if possible.
