There is a train of thought that pulling CB as switches can

My experience with Garmin stuff is limited to the 530. I would never pull
the CB for it without first turning the unit off.


Why Sam? I'm just starting to play with one, and I'm curious.

It is a complex piece of electronics. When you turn it off with the
power switch it might shut down in stages. That is stuff only Garmin
and a savvy avionics tech knows. When you pull the circuit breaker there
is no opportunity for the device to power down.
