As far as I was aware of the Duo RMI only worked only with Nav2 and ADF1 frequencies. This is the most common found in the default aircraft of FSX. As well in many other aircraft.
There are duo ADF RMI gauges with the aid of a toggle between ADF1 and ADF2 I have seen in other aircraft. The clue to be had there is the installation of a second ADF receiver in the radio stack. Then in some cases on the RMI gauge itself would only display the ADF only on one needle, and you would toggle between both frequencies, as the other needle was used for Nav2 always.
You will have to keep your eye out for a aircraft that has a ADF 2 direction finder gauge in it, along with the gauge file that operates it.
VOR1 works only on VOR1 gauges, and so on. VOR1 will not work on a VOR2 gauge( RMI in this case ). The toggeling between VOR1 and VOR2 is done through the PFD VOR1 needle on the default aircraft for FSX. So when toggeling to VOR2 your PFD displays VOR2 as well as the Duo RMI gauge now.
Or just perhaps you have it in GPS mode and not Nav Mode.
