Did about five cycles of Update Availabe>Getting Ready>Update Available. Did it both from app and inside car, countdown to update starts, then once over it resets back to Update Available.
Contacted my local SC, this is the reply:
I would recommend trying to perform a scroll wheel reset, then trying to download the most recent firmware that shows is on your vehicle. If that does not work, let us know and we can try to cancel the firmware and re-send it a different way.
Will try in the evening tonight. I suspect they might have to push the update, hope the limited resources on my 1st gen MCU will not result in bricking.
