This is the last thing I can think of. You say that your Opn1 has had the hearing aid Firmware update to v5 using a Hi-Pro and cables because Oticon Opn Firmware updates cannot be done wirelessly. However, we have not seen evidence that your Opn1 has Firmware v5 and you can’t show us that evidence because you can’t Detect the hearing aid.
So how are you sure that the Opn1 Firmware is v5? Did your Audi show you this (Firmware: 5.0) from the Detect screen?
