Does anyone use a Phonak FM receiver with their ComPilot? It saves having to buy 2 as using it with the ComPilot, it goes to both aids. It also means that my Naidas stay as water resistant. If I upgrade HAs, I won't have Naida receivers that I am unable to use as my new aids may have changed shape etc. Does anyone else use the ComPilot and one FM receiver because of my reasons above? Or do people upgrade their FM systems as regularly as their aids? I'm thinking about this idea for the future but wondering what other people think? By the way, I do have Naida receivers which were funded but I'm thinking about the future.
