Please update software, it’s been without an update now for 5 years or more! ### 5/5 — Works great *2024-04-03, version 2.9* You can have multiple devices able to control the volume and music stream at the same time, very useful. The access to almost all radio stations in the world is AMAZING! ### 1/5 — IPhone XR running IOS 15 doesn't work *2022-11-23, version 2.3* My IPhone XR running IOS 15, X-66 app doesn't detect my wifi address but my LTE address. Thus cannot find X-66 amp during scanning because the app thinks they are not in the same network. ## Frequently asked questions about Factor Electronics X ### What devices is Factor Electronics X-66 compatible with?
