Does the Audi need additional training from Phonak for upgrading the software to Ultra?
Probably no? I have just done it myself, simply I launched the Target software, updated it, and then when I went to the list of my fittings, I was notified about a possible update. Then there was a few mouse clicks. That’s all.
Is it worth going to another Audi and pay for the upgrade since I wouldn’t have a service agreement with her, unlike in the case with my current Audi?
It’s free upgrade. You should not paying for it. The improvements are mainly in the Spheric program, although in my case I have more headroom for maximum P receiver output - from ~3200 Hz (slightly) to 9600 Hz (even 11 “” more than before firmware upgrade).
