No way of telling for sure but a notification pops up only when im in my car saying potential trip detected I woiuld assume it is seeing the device before showing ready for a journey.
I guess I would be wanting to know if the “device” actually has the capacity to “forget” the old phone and actually pair with the new phone. I might ask this of the support team if I could not confirm that I see the “device” connected in the bluetooth settings.
