Use the Autocom 4036 to connect a monaural bike-powered audio device like an older GPS or most radar detectors, to a bike-powered Autocom system.
Commonly referred to as a ground loop isolation adapter, the 4036 eliminates hum and alternator whine between two bike powered devices.
It's not necessary to use an isolation adapter if either the audio device or the Autocom hub - like the Logic hub, is powered with internal batteries, rather than bike power.
The 4036 is suitable for an audio device that has one-way audio OUTPUT.
