Rolling Circle you're OTT on this one. You are implying that, if you do not have any VOR equipment fitted, you can fly in IMC but, if you have a non-immune VOR (even if you don't switch it on) you can't. This is obviously absurd. The ANO is the legal document, not the AIC.
With regard to comms immunity, GA have a waiver on FM immunity for comms equipment.
