Nope...
Got V+, n-Vi & 112x.... the V+ remote won't control either naim 2ch 0r n-Vi/AV2 volume.
Spent hours going through different codes... no joy!
However, I do have all my kit operated by one remote.....
Had to be programmed by my dealer, and wasn't cheap.... but factored in with some X10 wiring control it'll even adjust the lighting when I hit Play DVD
I find it more useful in my system as I have 5 sources.... one or two buttons is the most it takes to power up/down the kit I don't want to listen to and put the n-Vi and 112x on the correct inputs.
If your n-Vi only deals with itself and the v+ as sources then your best bet is to carry on as you are....
I tried a logitech Harmony but it doesn't get on too well with an n-Vi... as the n-Vi behaves like an AV2 & DVD5 together it's a single box that acts like 2 devices, which is where the Harmony gets out of step.
