The Garmin 010-12523-00 fist microphone extension cable is an original 12-pin microphone extension cable for compatible Garmin VHF marine radios. It increases the distance between the fixed VHF radio and the fist microphone, allowing the microphone to be placed in a more practical position at the helm, chart table or another control position onboard.
This 3 metre version is suitable for installations where the standard microphone cable is not long enough. The cable is designed for Garmin VHF systems with a compatible 12-pin fist microphone connection and is not a universal Ethernet, NMEA 2000 or power cable.
Always check the exact VHF radio model, connector and required cable length before ordering. A 10 metre version is also available under a different part number for longer installations.
