Back programming for the GMA 345 Audio Panel

[Tanille DeLair]

Does anyone have the back programming for the Garmin GMA 345 Audio Panel? Installed and everything works beautifully except for the volume on incoming communication/radio transmissions. Volume cranked, sounds perfect on radio 1 and 2 with engine off, able to hear at 1k RPMs, faint at 1800 RPMs, and unable to understand at 2400 RPMs on both radios.

Volume on incoming communication/radio transmissions is regulated by VHF radio‘s knobs.
