As it stands I just multiply the percent charge remaining by 3 to get an estimate of range. Glad to see they've revised the nav estimate and look forward to this being rolled into the main display.
Once 2.0.52 is pushed to my car, also looking forward to the mobile key improvements whatever they may be. After initially being wary, I switched to mobile key on iPhone from the key fob and have been pleasantly surprised how well it works. I really don't mind occasionally pressing the handle to unlock - after all, I need to touch the handle no matter what to open the door - and have not yet had to resort to the valet card.
