Here are the new things I have found thus far (without spending any time looking) in V4 that were not present in the previous iteration:
- Can turn the Environment (AC) on the home screen - since this is the #1 thing I do with the app, this is a great improvement to me.
- Set charging level on home screen
- Shopping for accessories
I will add to the list of I find more
I have not yet found anything that you can't do in the updated app that you could do previously (other than than have my white car look as good
)
