can you set "preconditioning" from the Polestar app 5-10 mins before you leave?
can a User set up BT or only an Admin? Not quite clear in the vids.
I assume I can choose whether to leave contacts to the phone or not for a User?
You can start climate preconditioning from the app, but if it's only a minute or two there probably won't be time for the car to be completely warmed/cooled to 72F.
A non-admin user can configure bluetooth for a phone as far as I know - I only have an admin profile as no one else really ever drives my car. I have set up other profiles in the past, but long ago I did a factory reset just to see if the early PAK would work better.
As someone else suggested, I would just set up a new profile and add your phone/sync contacts (or not!) and then just delete the profile completely before you return the car. That will delete all the data associated with that profile.
Above are just my suggestions, hopefully they help a bit.
