Bumbleberry + Crumble = Yum!
I have both located the problem and found the solution for the intermittent audio problem heard when running the Garmin GPS through an Autocom amplifier: the power lead/audio lead (pigtail) sold by Garmin for the Autocom has a faulty wire connection to the audio pigtail. This results in low volume or no audio output at all. The solution is to remove the female end of the Garmin product (pigtail) and the male end of the Autocom isolated audio cable (jack), then solder the wires together.
