    Was adjusting the sidetone up a little the other day and fixed that problem, but I was wondering what the mic setting is and running it up or down, does what?

    I didn’t see it mentioned in the Garmin Install document.

    You can only adjust the GNS 430 side tone on the frequencies of: 118.000, 127.000, and 136.975 MHz.

    I would imagine it's the mic gain.

    Correct, I adjusted it on the right frequencies. I was just curious on the Mic.
