Hi there, hoping someone might be able help. Just bought a nad D 3020 v2 and got it set up. Works fine with my turntable but when I try to pair it with my iPhone it’s just not showing as an available device. Tried it with my son’s android phone and the same thing. The user manual doesn’t say you have to do anything to make the amp discoverable so I am at a loss. Any suggestions gratefully received!
