Having said that, how often is a light aircraft going to still have nav radios

Assuming by "nav radios" you're willing to count anything I can navigate
with, this can easily happen since I always have a handheld GPS with me.
I do also carry a handheld comm, but do not have a link to an external
antenna so I'm not convinced I could always reach someone with it.
