Modern airplanes, like a Cirrus, don't have DME and use a GPS-derived DME on the PFD. I'm trying to simulate a loss of GPS signal, which works fine on the moving map, but DME information keeps working normally.
I tried failing all GPS, DME units and everything related I could find on the failure page, but the DME information is still present on the PFD when I tune a VOR, making it impossible to practice a full loss of GPS signal.
I know I can hide that by disabling the bearing pointers, but using the bearing pointers is really important and they don't depend on GPS, so they would be working in a GPS loss scenario.
