Product Questions

What are the dimensions of the unit please?

The dome measures 92mm in diameter and 46mm in height.


Rate the answer?
Does this receiver produce Nema 2000 via its connection cable or is there another interface required before it joins the network ?


This does not output NMEA 2000 data and instead must connect directly to a Garmin device with a BNC input. You can view a list of compatible devices on the Garmin website here


Rate the answer?
will a ga38 fit a garmin 178c

We are informed that the GA38 is a direct replacement for the original GA29 supplied as an option with the unit so it should be compatible.


Rate the answer?
Could you please advise if this unit will connect via a nmea 0183 cable?

The antenna has a BNC connector and will not connect via NMEA.
