Com 2 not working

[jacobcrabb7]

Hey guys! Trying to figure out what’s wrong with my setup, why I can’t get any audio to come through on com 2 of the 345.

GMA 345
Garmin SL30
530w

When I put in a frequency (tried different ones) into the SL30 and turn on com 2 on the 345 I’m not getting anything. I’ve tried volume and made sure it’s on com not nav. Any suggestions?

Thanks!

squelch switch?
lose wire?

When I pull the squelch knob there’s no sound change.
Will check for loose wire.
