I was told from more than one knowledgeable source (which I know
@JVBulman qualifies as) that the new Nyon does need to be brought in to the shop so that the bike can be attached to Bosch diagnostic system and the Nyon needs to be registered to the bike using the Bosch software which is only available in a certified Bosch facility. That was definitely not true of the earlier Nyon version which I installed entirely on my own and worked right away without any motor firmware handshake needed to establish communication between them.
Was the information given me about the new Nyon requiring an office visit not accurate?
