I was actually thinking the same thing few days ago. I suppose
it would cut the vario sound off when radio is receiving, and also
during transmit. Could be useful?

My new vario (LXNAV V7) requires an external speaker. My
radio Dittel

happens to have an input Audio signal. According to the
manual, that

input is processed and sent to the speaker of the radio. It
looks that I
c=

speaker [Obvious
t=

and radio

sound volume

the vario will still be adjusted from the Vario.=20

The main benefit is to eliminate the need to lodge a speaker
behind my
pane=
l and use the existing Radio speaker behind me. In addition, I
assume that
=
during transmission, the Radio will shut off the speaker, thus
eliminating

the Bip Bip of the vario from my communications.

Does anyone have experience with this approach? What are
the pros and cons?

Thanks,
