Garmin GBT 10 Bennett Trim Tab NMEA 2000 Analog Adapter
The new NMEA 2000 analog adapters are the perfect accessories to bring any helm into the digital age. Simple to install and easy to set up, the NMEA 2000 adapters take signals generated by traditional analog gauges and sensors and convert that data into NMEA 2000 format. The data can then be broadcast over NMEA 2000 protocol to the Garmin GMI 10 multifunction instrument display. The combination of these adapters with a Garmin GMI 10 will transform even the most out-of-date dashboard into a glass, digital helm.
