Using HDG Mode Question

[GAJ1952]

Can somebody please try this and see if they get a CTD with the GTNXi

Load a default aeroplane in MSFS such as the C172 (non glass cockpit)
Start the engine and turn on the avionics
Start the GTNXi, go to GTN750Xi settings
Where it says Connect GPS to Autopilot, select 'Heading'
In the GTNXi go to Map and ensure VLOC is selected via the CDI switch
Load a very simple flight plan
Select the Map display
Press the CDI to change the mode to GPS

Do you get a GTNXi CTD within about 5 seconds ?
