How do I switch the NAV radio frequency from standby to active?! I can neither find a toggle switch to do it nor from within the FMS. What am I doing wrong? Thanks.
@Eddy the answer is annoyingly simple... Surprisingly, all one has to do is to left click on the NAV radio on/off switch (the left of the two switches). I must have clicked everything in the cockpit before making my discovery. I ought to have known having bought loads of Carenado stuff.
