Using the MyChevrolet app I can precondition the Cabin only if plugged in. If not plugged in I get an error message: Encountered a vehicle error. Please ensure the keys are not in vehicle and try again. There are no keys in the Bolt and I can Precondition the Cabin with the remote key not plugged in. Works just fine. Only mode that does not work is using the MyChevrolet app not plugged in.
