Thanks for the tip(s) about the maps -- at this point in time, I'll probably stick with using my cell phone for most navigational purposes. What effect, if any, does charging a cell phone have on range? With a limited range in the ~40 mile area, I'm hesitant to do even little things like charge my cell phone while driving!
You do not need the 3G modem upgrade for SiriusXM Traffic since it just uses the satellite system. You do need the modem upgrade to get updated public charger information on the navigation system and to use the remote climate control activation and other EV Connect (CarWings) features. Cellular phone charging has absolutely no impact to range so don't worry about it.
To answer some of your other questions: The maximum cold inflation pressure of the OEM Bridgestone Ecopias is 44 psi and I highly recommend that you run them at that for best handling, wet/dry traction, tire wear, and range. The A/C is very efficient and has minimal impact on range unless the heating elements in the little hot water tank are activated (this is another reason to implement the heater cutoff modification).
