I'm also guessing some OTA updates are working. I also have some pretty high tech bicycle gear and note that hardware updates work OTA as well. Ie, I've done updates where the ROM is flashed. It's always a slow process, but it's been working on several devices by different companies for years. 'Not sure why you'd need that direct connection through a cable. But I'm a structural engineer, not a software engineer, so my understanding is quite limited.It would be my guess OTA updates do work fine one or some of the computers on board, however there are some computers on board that need a physical connection to be updated.
